Online Professional Development Sessions

Tonight!

Catalysing a Culture of Curiosity in Mathematics

Presented by John Rowe

Doing mathematics is an amazing way to truly harness the curiosity we naturally bring to things that capture our attention. We play with ideas to explore our intuition and attempt to reason the way the world works. We create models that tell stories of patterns and relationships between what we can see and what we cannot, between what we understand and what we do not.

Teachers can be a catalyst for creating a culture of curiosity in mathematics, serving as a model for working mathematically conducive to learning experiences where students are captivated by the beauty of mathematics.

This webinar will provide participants with examples of how we might foster a classroom culture where students ask more questions than their teacher and where learning is a process of reflection, sharing the insights made and resolutions reached.

Building Visual Patterns Into Your Warmup Routine

Presented by Fawn Nguyen

Calling all teachers (grades 1 through 12+) who are new to visual patterns! I’d love to share with you how I use visual patterns as one of my warmup routines. I’ll share key questions to ask students, helpful structures to build algebraic reasoning, and ways to kick it up a few notches once your students are familiar with working with patterns. With faithful implementation, using visual patterns provides a powerful tool to build confidence and flexibility in writing equations.

Readings for Pleasure

One of the symptoms of beginning the school year is that I sometimes find myself with less time or energy to read or study mathematics purely for pleasure. It’s a shame, really, because one of the sources from which I draw strength and joy in teaching mathematics is the joy I feel when I do mathematics for its own sake either at home or in community with others.

Instead of sharing resources dealing directly with the classroom this week, I’ll shout out a few longer-form resources and recent articles about STEM, which can be read with students or read simply for fun. Maybe you will find some of these articles enticing or, at least, a respite from the demands and excitement of the new school year.

Quanta Magazine

If you haven’t already, spend some time seeing if you enjoy the articles in Quanta Magazine. The publication dives into current science and math research in an accessible way through what they describe as “public service journalism.” Just as many math educators strive to spread the message that everyone is a math person, Quanta approaches math and science journalism with a similar lens: that all readers are STEM people capable of accessing the forefronts of the field in meaningful ways.

Dr. Chanda Prescod-Weinstein (@IBJIYONGI) teaches us about Ann Nelson, a theoretical particle physicist who passed away last month and who fought against misogyny and racism in the scientific profession.

Kevin Hartnett (@KSHartnett), in A Mathematical Model Unlocks the Secrets of Vision, helps us understand how mathematics can be used to explain how our brains create images of the world despite receiving very little actual information from our visual system.

Erica Klarreich (@EricaKlarreich), in Decades-Old Computer Science Conjecture Solved in Two Pages, breaks down a proof about the structure of computer circuits using analogies and beautifully crafted diagrams.

Symmetry Magazine

Symmetry Magazine is about particle physics with links to outside resources but also many articles of its own. I only learned about the magazine recently through the article Channeling Shuri as a physicist at Wakandacon, which talks about Wakandacon, a 3-day Afro-Futuristic celebration that took place in Chicago last July.

AMS Blogs

The American Mathematical Society website hosts a diverse body of blogs about mathematics and the mathematics profession. I have recently enjoyed reading entries from inclusion/exclusion, a blog about underrepresented groups in mathematics. In particular, read Decolonize Academia #KūKiaʻiMauna, which takes up the Thirty Meter Telescope (TMT) project planned on Mauna Kea and which challenges readers to think about ones research as also impacting the world outside the explicit inquiry of the researcher.

The passion we feel for the math and science we teach is one way in which we continue to push ourselves as educators, but that passion must be nourished and sustained. Whatever you do to sustain your passion—whether it’s doing math on your own, with adults, or with your students—just make sure that passion drives you to love your students for who they are, regardless of whether they share your same love for the field.

Problems of Practice

As researchers, we spend a lot of time with experienced secondary math teachers thinking about, well, math teaching. In the context of a larger study, we’ve been looking at conversations with small groups of teachers where they reflect on their practice with the help of video and audio from one of their recent lessons. We’ve discovered that these conversations are full of rich problems of practice –– questions and concerns that these experienced teachers grapple with in their everyday work. Across the groups, it became clear that many teachers faced similar problems, despite teaching in different schools and having varied backgrounds. Here are some of the challenges they are facing in their classrooms (out of 33 conversations with 15 different experienced math  teachers):

This chart shows the top six most commonly surfaced problems of practice in the context of these conversations. Across these discussions, there were 1,331 instances where teachers or facilitators problematized the practice of teaching. Of these instances, teachers wondered about setting up effective group work 193 times, making this particular problem of practice the most frequently named. Clearly, facilitating group work is incredibly complex, dynamic, and challenging. The second most frequent issue involved preserving instruction to the intended lesson goals. The prevalence of this challenge indicates how hard it is to make decisions that preserve the intent of instruction in the realities of the classroom. Although it did not make the top five, we found it noteworthy that the question  ‘How do I manage the constraints and demands of being a teacher’, came in sixth place. This suggests that what teachers are able to do does not entirely depend on them: teaching goes far beyond the classroom and into navigating a complicated world.

The entire process of cataloging problems of practice, as well as the sheer number that we found, indicates that even the most experienced of teachers face a multitude of challenges over the course of their days in planning, implementation, and in-the-moment decision making.

As the new school year begins, what problems of practice are you facing? What are you discussing with colleagues as you head back to school?

Back to Work

It’s back to school time for educators in Ontario, Canada and this long weekend I am looking ahead and accepting what promises to be an adventurous school year. Teacher contracts expired yesterday, and provincial leaders continue to undermine public education; yet I know many educators who are preparing to return to classrooms and supporting roles not with trepidation but a renewed commitment to better serve students and their communities.

In her closing keynote for the Virtual Conference on Humanizing Mathematics (#VConHM) hosted by Sameer Shah (@SamJShah2) and myself, Dr. Rochelle Gutiérrez offers her insightful thoughts on rehumanizing mathematics and invites us to take stock of our praxis with the following reflexive questions:

  1. In mathematics, what feels dehumanizing to my students?
  2. In mathematics, what feels dehumanizing to me, other teachers, or families/communities?
  3. What might feel more rehumanizing?
  4. Who can help me rehumanize this space?

Let it be known this is not entry-level Equity 101 Work. This Work requires continual reading, processing, collaborating and most importantly dialogue with critical thought partners to push through cognitive dissonance.

Upcoming this week is a new chat #GhostsInTheSchoolyard led by @DingleTeach@MochaMomma, and @TeachNext_TMB to prepare #MTBoS for the Centennial Annual Exposition and Meeting of NCTM in Chicago in April of 2020. Please check out Marian’s latest blog post, Mathematical Ghosts.

By the time you read these words, Ontario educators will be almost halfway through the first day of the 2019-2020 scholastic year and in Dr. Gutiérrez’s words,

“I am hopeful about where we are as a field in being willing to acknowledge the violence that is regularly perpetuated (knowingly and unknowingly) against students, teachers, faculty, and members of society through mathematical practices, policies, and structures.” 

Wishing you a scholastic year of discomfort, unlearning, and relearning.

PART 2: How Might Our Beliefs Impact Our Identity as Mathematics Educators?

Presented by Megan Holmstrom and Ryan Grady

As we engage in professional development with teachers mathematics teaching & learning, we have found that asking three questions is a crucial place to begin the work with any group. As you think about the teaching and learning teams you are a part of, consider these three questions:

  1. Who are we?
  2. Why are we doing this?
  3. Why are we doing this, this way?

Further, NCTM’s Guiding Principles for School Mathematics states that, “Professionalism [exists] in an excellent mathematics program, [when] educators hold themselves and their colleagues accountable for the mathematical success of every student and for their personal and collective professional growth toward effective teaching and learning of mathematics” (Principles to Actions p.5 – NCTM 2014). How are we holding our collective accountability in shared professional growth?

Please note: this is Part 2, consider reviewing our conversation from June 18 as front-loading for this chat.

Observational Feedback that Sticks: Google and Extensions that Create Actionable Feedback

Presenters:  Brandi Simpson & Brooke Lucio

Based on the work of Chip and Dan Heath, authors of Teaching That Sticks, this session will demonstrate how observational feedback can “find the core” to develop a productive coaching relationship. We will share our protocols and system for providing feedback that integrates AutoCrat and the Google Suite. Participants will walk away with the skills to design and customize feedback tools to meet their needs at any level.

Welcome Back!

The Virtual Conference on Humanizing Mathematics

Last summer, Sameer Shah (@SamJShah2) hosted a Virtual Conference on Mathematical Flavors featuring blog posts from educators who shared their everyday practices that shaped students’ understanding of mathematics. This summer, he invited me to collaborate with him and I accepted the incredible opportunity to create a space for critical engagement and reflection on a theme that has been central to my learning this year; belonging. Our initial conversation revealed a mutual interest in the doing of mathematics as a human endeavor, mathematical identity, belonging in mathematics education spaces, and the rehumanizing of mathematics.

We offer to you for the month of August, the Virtual Conference on Humanizing Mathematics featuring keynote bloggers who are addressing the prompt(s):

How do you highlight that the doing of mathematics is a human endeavor?

How do you express your identity as a doer of mathematics to, and share your “why” for doing mathematics with, kids?

#MTBoS contributors from K-16 are also participating by responding to weekly mini-questions and sharing their mathematical experiences, mathematical identities, and reflecting on what scholarly terms (like ‘mathematics for human flourishing’ and ‘re-humanizing mathematics’) have to come mean in their practice.

Click on the image below to introduce our topic for Week 4 of the conference:

Readers of the first edition of this school year’s GMD Newsletter are the first to know that we are honored to host Dr. Rochelle Guttiérez as our closing keynote blogger on Thursday, August 29, 2019.

We whole-heartedly invite you to visit the virtual convention center and learn with us.

Getting Specific About Equity and Humanizing Mathematics

I’d like to highlight what I see as a burgeoning trend in many parts of the math edutwittersphere. Roughly, this trend involves ideas like equity, humanizing mathematics, critical theory, and power and identity. This trend seems to be distinct from other topics in math ed like cognitive science and mindset research but still closely connected, and I’ve noticed at least three general types of activities surrounding this idea of equity, humanizing mathematics, and applying a critical lens:

  1. Spread, Reflect, Critique: Calling out others and ourselves to attend more fully to the work of unlearning, self-reflection, and critique.
  2. Research: Collecting, analyzing, and reporting qualitative data on moves and practices that support this work.
  3. Specification: Being specific about the ways we operationalize ideas about equity and humanizing mathematics.

Item 3 might be the toughest to do well but it’s also vital for us if we want to move forward as a math ed community. Thankfully, the Virtual Conference on Humanizing Mathematics represents one of several ways we as math educators are helping each other put our ideas about equity and humanizing mathematics into practice. The specific blog posts and Twitter threads can be found at the convention center, and instructions for submitting a contribution can be found here.

One Twitter thread caught my eye. It was by Jimmy Pai (@PaiMath), who went through every single contribution from week one and gave thoughtful, reflective comments on each one.

His feedback highlights the kind of conversations and exchange that can occur when we talk at all levels of grain size, from the critical-analogical-macroscopic reflections of Marian (@DingleTeach) and Hema’s (@HKhodai) keynote address to Chris’s (@cluzniak) share of #DebateMath and journals.

Besides the virtual conference, @JessicaTilli1 asked folx: “If you could conduct interviews for a middle school math teaching position, what are some questions you would ask?”. This triggered a host of responses, many in the realm of equity, humanizing math, and critical theory. I’ll end by highlighting just a few:

Great Prompts from Summer

I love when a good prompt catches fire on Twitter. The result is a mile long thread full of ideas, strategies, advice, etc that’s just loaded with goodness. Do these things have a name?  (I feel like they need a name!)  Below I’ve shared a few of these loaded threads.  Click on the image of the tweet to take you to the thread and get scrolling!

As we start the new year it’s always good to have some norms:

Math is beautiful.  Check out this collection of “mathematical mindfulls”:

If you’re new to the profession there’s an embarrassment of riches here. Going into my 15th year next week there’s plenty I need to hear too!

For everyone who finished their reading lists this summer (I’m joking, right?), Ibram X. Kendi’s book “How to Be an Antiracist” comes out today and inspired this:

When you find amazing threads like this #pushsend and chime in, and/or retweet so the rest of us don’t miss all the goodness!  Happy Back to School Everybody!

Another School Year Comes to an End…

Ends and New Beginnings

Since this is our team’s last newsletter of the year, I wanted to share two resources that represent a typical teacher end and a typical teacher beginning.

In the End…

There is usually a test. At least, that’s how it is in NYC public schools. My 7th graders – yes, SEVENTH GRADERS – are currently stressed about an end-of-year math exam called the Regents. It’s not a great way to end an otherwise great year of relationship building, inside jokes, and shared tribulations, but it is what it is.

In the spirit of thinking about math exams, please read @howiehua’s piece in Edutopia on A Strategy for Reducing Math Test Anxiety. In sum, it’s based on giving students a chance to have a brief pre-test conversation with the test in hand. He shares an anecdote where one student talks about having pre-test jitters, and the pre-test conversations help calm their insecurities. He also notes that since he and his co-teacher encourage discussion and collaboration in class, it only makes sense to test the way they teach. I can say from personal experience that if you ever implement this strategy in your class, it will be some of the most intense five minutes of mathematical discussion you’ll see.

In the Beginning…

Teachers do new stuff to their classrooms. This year, I put up many of @MrCoreyMath’s mathematician posters in my room. It’s a thoughtful and extensive selection of mathematicians from diverse backgrounds, which I used this year as a first step in a larger campaign to broaden my students’ conceptions of who does mathematics.

In addition, @jocedage recently tweeted a link to STEM role model posters, which were released for International Women’s Day and which are now available in multiple languages. They look amazing!

In Summary…

Thank you to everyone who read our newsletter this year and, of course, to our amazing editor, @thegozaway. I’ve learned so much participating in the GMD this year and look forward to learning even more!

Melvin Peralta (@melvinmperalta)

#BreakRank

It was September of last year when Marian Dingle (@DingleTeach) first brought the Global Math Department Newsletter to my attention and being the exceptional educator she is, she sparked an idea and waited patiently for it to ignite my passion. It wasn’t until seven months later she highlighted my first blog post on my experience as a first-time attendee at NCTM 2019 in San Diego and I started to contribute to the GMD Newsletter.

This is my last post for the school year and I must thank Matthew Oldridge (@MatthewOldridge) for passing the baton and sharing this opportunity with me. I appreciate Nate Goza (@thegozaway) for connecting with me and inviting my thoughts and reflections into this new virtual space.

This week, I am highlighting the #ClearTheAir and #BreakRank chat that Christie Nold (@ChristieNold) and Scott Bayer (@Lyricalswordz) hosted on Wednesday, June 5, 2019 in which they discussed “Racism, whiteness, and burnout in antiracism movements: How white racial justice activists elevate burnout in racial justice activists of color in the United States” by Paul Gorski (@PGorski) and Noura Erakat (@4Noura).

Specifically, I draw your attention to a few sub-threads within this chat and invite you to review them with a focus on how crucial these conversations are to the intentional design of mathematical learning spaces.

Let us start with a sub-thread featuring JoyAnn Boudreau (@MrsBoudreau) in which participants discuss setting norms in professional learning spaces with fellow mathematics educators as well as co-constructing them in mathematics classes with our students. The prevailing topics are presuming positive intention, tone policing, a right way to do things, and individual personality traits that hinder our work.

Alice Jane Grimm (@Alice_J_Grimm) beautifully articulated a brief sub-thread about mandatory gender pronoun introductions that I have bookmarked so I may return to it again when next I plan professional learning for colleagues or classroom introductions for students.

Alecia Ford (@AleciaHiggFord) shared a brain break game she has used successfully with her students that creates space to talk openly about race and identity while developing fluency with fractions.

Some of us are settling into summer break routines and slowly shedding layers of this school year’s experiences and others of us are preparing to wrap up the school year with a final perseverance. Let our reflections and forward planning include how we intentionally establish psychological safety for students and colleagues to be and learn in mathematical spaces. Let the goal be to thrive not just survive. (Shout out to Bettina Love.)

As Val Brown (@ValeriaBrownEdu) stated at a Teaching Tolerance workshop in February,  “This is your homework. For the rest of your life.”

Thank you for reading and engaging,

Hema Khodai (@HKhodai)

Summer Time!

This can be a time of joy for teachers to take a much needed break, to rejuvenate, and gather new ideas for next year.  For our students, it can be stressful without the routine of seeing friends, having a safe space with caring adults on the daily. Therefore I offer you a nationwide resource to share with students and families (Thank you @edcampOSjr for sharing)

As we reflect on what worked throughout the year, I plan to be more intentional about building and maintaining relationships with and among my students; I was drawn to the thread started by @EmilyAnderle about morning meetings.  This is a strategy often used in my own child’s 1st grade classroom; I am certain with intentional use in a secondary classroom could be a positive change.

Finally, as we set to start the cycle again (not literally an infinite loop) I was pleased to learn some mathematical content knowledge started on this thread:

Hopefully, we all get a chance to relax (for those still in the classroom I wish you the best).  It has been a pleasure sharing my twitter treasure hunts with the Global Math Department audience.  I have met many virtual and IRL friends.  Thanks @thegozaway for inviting me into this space.

Jump-start Number Sense and Reasoning in 10 Minutes
Presented by John SanGiovanni
Do your students struggle with reasoning about numbers? Are they challenged to think about the reasonableness of their solutions? Are you looking for practical, high-quality tasks to engage students and ignite discussion? In this session, participants learn about dynamic, doable activities engage students in reasoning and discussion. A collection of ready-for-use resources will be provided and explored so that pursuit of number sense becomes a daily routine. These resources naturally complement each and every lesson in any K-2, 3-5, or 6-8 mathematics class regardless of the “core” program.

Last week, Ranjani Krishnan presented “Teacher Cloning.” If you missed it, you can catch the recording here.

The #MTBoS Never Sleeps

In Preparation for Next Year

While the end of the school year is a time to reflect, I’m also inspired by the potential of the next school year. In particular, I have been thinking about how I might develop students’ identities as mathematicians and how this relates to their futures.

“I’m preparing you for college” is a phrase Patricia Vandenberg (@VbergMath) confessed she would use to defend some of her class policies. In a tweet, she asked math professors to share what they’d truly like to see in their math students.

Responses varied, but some common themes were (1) teach students how to take ownership of their learning through organization and engagement, (2) encourage students to take risks and embrace ambiguity, and (3) instead of using this phrase, meet students where they are.

Year-end Survey Options

If you are looking for some ideas for a year-end survey, Deidre O’Connor (@historywithmsoc) posted this tweet and has a thread loaded with great suggestions that are general enough for any subject and any grade level.

By Amber Thienel
@amberthienel

Notes from an Inspired Editor
Adding to the suggestions of the authors above, Matt Vaudrey has written quite a bit about Teacher Report Cards. It’s brilliant stuff and a wonderful way to build culture at the beginning, middle, and end of the year. How would your classroom culture changed if you considered doing a Teacher Report Card after the first month of school? Would your students open up more? Would the autonomy and authority shift in the classroom?

Here are onetwo, and three short (less than 5 minute reads) blog posts from Matt’s site. Dive in! And let us know what you think.

Teacher Cloning
Presented by:  Ranjani Krishnan
I am not enough’ is the feeling I used to get everyday after each class and each day’s work. I wish I could clone myself and spread myself around the classroom so I can meet the needs of every student. Luckily, an online program named Gauss Academy Webwork came to my rescue. With this tool students work online on challenging problems, get instant feedback, engage in a risk-free yet productive struggle, while, I, the teacher can interact with students meaningfully by conducting discussions at the white board with these students about these problems. I have also been cutting my class sizes in half, so to speak, by setting different groups of students into different zones of productivity. One group would work on video note-taking, while the other would work on Gauss Academy Webwork. I redefined video instruction for my classes. After completing video note-taking, students would show me their notes, answer the inquiries posed in the videos, summarize notes, and then debrief with a classmate. I wouldn’t call my video note-taking model “flipping” the classroom, however. I am excited to say that with these two “cloning” tools, I am able to bring face-to-face conversation with students back!

The #MTBoS Never Sleeps

#MathPhoto19

The Math Photo Challenge is a series of 10 weekly photo prompts posted to Twitter. Each week, participants take photos inspired by that week’s prompt and then share them on Twitter using the hashtag #MathPhoto19. This challenge is a fun way to interact with other #MTBoS teachers and to practice viewing the world through a mathematical lens. Anyone can check out the collection of photos on Twitter by searching the hashtag #MathPhoto19 or at the website https://mathphoto19.wordpress.com/ organized by Carl Oliver. This year’s photo challenge will start on Thursday, June 13th. Anyone can join in at any time.

This is the fifth year of the Math Photo Challenge. The first year was organized by Malke Rosenfeld with assistance and contributions from numerous members of the #MTBoS. It was initially called the Summer Math Photo Challenge. Following years dropped “Summer” from the name in recognition of all the participants from the Southern Hemisphere for whom Summer is still a long way off.

The first week’s challenge will be the number #five to celebrate the fifth year of this annual challenge. Check it out!

I’m Not A Game of Thrones Guy

I could give a rip about Game of Thrones. I’m one of the few people who has never watched a single episode. I’m not living under a rock. I do know it is popular (or was) and there are some really passionate fans.

One of my favorite feeds is Cool Infographics and they recently posted Visualizing how Fans Rated the Last Season of Game of Thrones.

First, I appreciate how the post included fan ratings of the last season of other shows. Secondly, I love the visual math landscape of all the infographics. Thirdly, a question I have is what does this say about us as consumers of television? Do we rate something poorly when it’s not what we “expected”? I don’t know. Lastly, I appreciate how the author, Randy Krum, expresses his hesitation about one of the axes. Krum says,

My only hesitation with the choices they made when designing these charts is the y-axis. I appreciate that they kept the scale consistent throughout all of the charts in the article, but the non-zero baseline starting at 4.5 is an odd choice. Non-zero baselines are generally a poor design practice, and can mislead viewers that aren’t paying close attention. It looks like using a non-zero baseline was chosen to maximize the visible differences between the ratings, but on a 0-10 scale, it wouldn’t have been much different with a true zero-baseline.

Krum is using a few of the Standards of Mathematical Practice. Can you identify which ones?

Just like I’m not a Game of Thrones guy, I wonder if we asked Krum about his math experience and if he would say, “I’m not a math guy.” I would beg to differ. My challenge to you all is to question anyone who says, “I’m not a math person.” Rubbish. Don’t let them off the hook. Find out why they said that and join the conversation Tisha Jones and I have been having.

Diversity With Intentionality

If you haven’t already seen this tweet from Kristopher Childs, it sparked an interesting conversation this week. And after reading the inaugural blog post from Makeda Brome, I think they both pair well together. Her post, entitled Diversity with Intentionality begins with this line:

“Yes, this is another post about diversity in mathematics.”

She writes about how such goals as diversity and equity can not be achieved haphazardly, but rather with deliberate intent. She uses her recent NCTM experience as an example of how she intentionally sought the conference experience that fulfilled her. I won’t give any more away, but it should be read.

Back to the above discussion, among the pros, there was the power of articulating the importance of diversity and inclusion in math. Among the cons, there was the potential harm of these practices being seen as separate add-ons instead of naturally embedded practices. I keep thinking about intention. How can this type of intentionality be ensured?

The topic of this week’s #ICTM chat was SEL and its relation to mathematical identity hosted by Tyrone Martinez-Black. This was one of the thoughtful questions asked:

The first two statements highlight the importance of identity and agency. It connects to the next image of recent Brandeis mathematics graduate @Algebrandis, as she wears her identity and agency, and intends
to continue to pursue her doctorate.

Math Buddies:  Effective Peer Tutoring

Presented by Kateri Thunder

Peer tutoring has the potential to accelerate student achievement (Hattie effect size = .53). In fact, under three conditions, the effect is has high on the person doing the tutoring as on the person being tutored. How do we orchestrate these meaningful interactions among peers? Come learn how to implement peer tutoring between two different grades for weekly math lessons. Unpack the three conditions that make peer tutoring effective and be inspired with ideas for your own “Math Buddies” lessons.

From the World of Math Ed…

All In

The Ontario Association for Mathematics Education held its annual conference in the nation’s capital this past week. Many thanks to the host chapter, @ComaOttawa, for the incredible planning and organization of this professional learning experience.

Many of us first time presenters, like myself, were comforted by friends, colleagues, and new acquaintances that offered words of wisdom to soothe frayed nerves, a lending hand to troubleshoot technical difficulties, and provide directions to water bottle refilling stations. Of particular note is the way fellow educators showed up to support first-time attendees and first-time presenters alike. This community of mathematics educators was all in.

Ilana Horn (@Ilana_Horn) spoke to members of the Ontario Mathematics Coordinators Association (@OMCAMath) about Designing Motivational Math Classrooms. She posed a question on belongingness, “What gets in the way of belonging in math class?”

The prominent student-centered message is mathematics educators are invited to create learning cultures in which students see themselves as doers of mathematics, to spark joy in their mathematical discoveries, to establish brave spaces where mathematical discourse and rough draft thinking/talking/writing is encouraged.

The emergent themes for educators in the sessions I attended at the OAME annual conference were identity, community, and vulnerability. Featured speakers, Sam Shah (@SamJShah2) and Matt Baker (@Stoodle) had a full lecture hall of educators roaring with laughter and then weeping into shirt sleeves as they shared their stories about the power of #TeacherVoice. Tracy Zager (@TracyZager) modeled a beautiful experience of community by sharing high-yield mathematical interactions and we were hooked as we worked independently and then collaboratively to discuss Magic Vs. Jamie Mitchell (@realJ_Mitchell) and Matt Coleman (@MrColemanArt) shared their journey of innovation and humbled us with their transparency and courage.

This tweet perfectly captures the spirit of #OAME2019 – a community of mathematics educators coming together to learn, share, and collaborate. Derek invited attendees of the mathematics conference to collaborate on a shared document in order to “learn about sessions that you missed…see what others took from the session…get some learning from a distance.” The Google Doc was 83 pages long at last check!

We will each have returned to our regularly scheduled life events by the time this article is published; however, the learning continues. Peruse the hashtags, take a look at the many presentations that have been shared by presenters, and keep sharing how you will action what you have learned at #OAMEChat.

@OAME2020 “In Focus” will be held at UOIT/Durham College in Oshawa, Ontario from May 7th – 8th, 2020. Stay tuned to oame.on.ca for details and practice your live-tweeting skills for #OAME2020.

A People’s History of Math

A couple of weeks ago, Anna Haensch (@extremefriday) asked the Twitterverse about suggestions for a “People’s History of Math”. There were lots of great replies, mostly about histories beyond the white, male, Eurocentric stories often told about mathematics.

One very thorough response came from Michael Barany (@MBarany). He warns against the common pitfall of framing non-Western math as taking place in the past and serving as a mere predecessor to modern mathematics. I was struck by his pointing out that this origin myth was actually created by a prejudiced process of early modern Europeans.

Barany’s thread continues, and he includes a handful of fascinating links I had never heard of. One essay that you might particularly enjoy is Lady Wranglers by Joy Rankin (@JoyMLRankin). The essay, along with Barany’s thread, helps readers reconsider the assumption that the history of math should be conceived as a linear march of progress. Rather, mathematics has had many moments of creating obstacles that people with marginalized identities have had to overcome. It’s a shame that so many popular books on mathematics, and even university courses on the history of mathematics, construct mathematics as a simple sum of the achievements of a few, positioned-as-brilliant men.

Other common names that came up in the thread include Sophie Germain, Srinivasa Ramanujan, and Hypatia of Alexandria. One name that came up I was happy to see was Marjorie Rice, a non-university-affiliated mathematician who made discoveries involving tessellating pentagons.

Finally, one book that was left out of the thread was recently tweeted about by Annie Perkins (@anniek_p) – Power in Numbers: The Rebel Women of Mathematics. Guess what’s next up on my reading list?

The #MTBoS Never Sleeps

Food For Thought on Accelerating & Tracking Students

In a recent NCTM (@nctm) article in Mathematics Teaching in the Middle School (@MTMS_at_NCTM), Sarah B. Bush (@sarahbbush) talks about ways middle schools can support the position in Catalyzing Change in High School Mathematics(2018). Her article, NCTM’s Catalyzing Change in High School Mathematics: Our Role in the Middle” is in the March 2019 issue.

She writes about de-tracking students because this practice leads to the success of more students: “We can all agree that students should not be denied access to the instruction needed to become mathematically literate and that students should not have qualitatively different mathematics learning experiences.”

When I saw Robert Kaplinsky’s (@robertkaplinskytweet asking why we do not accelerate students through English Language Arts (ELA) like we do with math, I immediately made a connection that I invite you to contribute to.

Dig deep into the thread because the conversation gets really interesting. For example, check out Patricia’s (@TeacherPrepTech) tweets about students having an emotional response to the speed of math class.

And don’t forget to check out Sarah B. Bush’s full article in the March issue of MTMS. Let’s continue this conversation.

Family Math Night

A couple weeks ago, my middle school hosted a Family Math Night. It was really special to see students and their families participating in math games, creating math art, and exploring mathematical ideas. If your school has never put together a Family Math Night, FamilyMathNight.com has tips on how to get started, and a twitter search of “Family Math Night” will leave you with plenty more ideas for stations.

What stood out to me the most was that every person involved with Family Math Night knew that each station had to be fun and accessible. As a result, there was a clear contrast of what was a valid and welcomed mathematical activity in Family Math Night versus the mathematical activities our curriculum. For example, if creating tessellations and estimating quantities are valid activities for Family Math Night, there must be potential for math play, art and estimation as a regular part of our daily instruction. I immediately thought of Kassia Wedekind’s talk at ShadowCon 2017 on math play, and Sara VanDerWerf’s play tables as strong starting points.

I also noticed students and their families looked confused at some stations, often asking, “that’s it?” It seemed like the difficulty of math in the activity wasn’t clear and they were looking for the catch. How could we have made connections to our curriculum and the Common Core Standards for Mathematical Practice, so that students and their families can have more conversations around math beyond our classrooms and in their homes and communities?

We know math is everywhere, and mathematical agency starts with helping our students and families understand that.

Christelle Rocha (@Maestra_Rocha)

Notes from an Inspired Editor
Part of my joy serving as an editor is reading deeply about what our team of writers bring to the table and making connections between ideas.

Like Christelle, I’ve been thinking a lot about our conversations as math educators with the non-teaching public (like Family Math Nights) and how we can make them better. I think we (math educators) can do more to reframe our work with parents (and other non-math-educators) by redefining what it means to do math.

I found this tweet by Mark Trushkowsky about #sidewalkmath, a project by Brian(@_b_p):

The thread is well-worth checking out. I appreciate the efforts folks are making to shift the dialogue about what it means to be a “math person” by bringing more math conversations into public spaces. I gave a talk recently about this topic to a (non-math-educator) conference about creativity. It’s my case for why and how we move the conversation forward. You can see a screencast of the talk here.

What do you do to shift the dialogue about what it means to do math with the general, non-teaching public? What works? What doesn’t? Participate in the conversation here.

From the World of Math Ed…

Avoiding Racial Equity Detours

I recall sitting in my school’s mandatory “Diversity and Inclusion” PD two weeks ago. Fifty-plus teachers and staff listened to our principal, a well-meaning man, talk cautiously about issues of race, gender, and status in our school. Besides citing the “statistic” (his word, which he emphasized) that our accelerated track had few students of color, he read from slides that defined terms such as “diversity”, “inclusion”, and “equity.” Then we watched a TED talk on implicit bias.

Near the end of the presentation, one teacher claimed that implicit bias doesn’t exist and “equity” only creates problems where there is none. Sensing the room’s rising discomfort, our principal was quick to assure his staff that he was not accusing them of racism. He went on to focus on how teachers and students talk about tracking in our school.

Then the meeting ended. That was it. No follow-up or questions. Just some slides on diversity and inclusion, a TED talk, which I fear sent our staff the message that inequity can be solved by fixing our psychology alone, some white fragility, some placating that fragility, and a pivot toward talking about status while keeping race and gender safely at arm’s-length.

I think this is why the article Avoiding Racial Equity Detours by Paul Gorski was so impactful when I found it strolling the streets of the Math Ed Internet Universe. Gorski starts with four “racial equity detours” embraced by schools that refuse to reckon with its reality of racial inequity. They are:

  1. Pacing-For-Privilege Detour: Coddles the feelings and fears of hesitant educators.
  2. Poverty of Culture Detour: Using vague notions of culture to explain everything.
  3. Deficit Ideology Detour: “Fixing” students through mindset and grit alone.
  4. Celebrating Diversity Detour: Using PoC as props for gentle diversity education.
Gorski also talks about five principles of “equity literacy” (which by the way reminds me of another useful term, “racial literacy”). It’s important to note these are not simple strategies to solve problems of equity but rather clotheslines on which to hang weightier conversations:
  1. Direct Confrontation Principle: “How is racism operating here?”
  2. Redistribution Principle: Redistributing access and opportunity to PoC.
  3. Prioritization Principle: Filtering every policy and practice through the lens of “How will this impact families and students of color?”
  4. Equity Ideology Principle: Developing deep understandings of racism and an ideological commitment to eliminate it.
  5. #FixInjusticeNotKids Principle: Eliminating racist conditions instead of focusing on efforts to “fix” kids.

What is Math?

I spend a lot of time thinking about what math is and why we spend so much time on it in school.  For me, mathematics is joyous and learning it also feels useful.  Not useful in the sense that I plan to “use it in my real life,” but useful in the sense that I am growing as a result of it.  I’m not sure I can explain that growth, nor can I quantify it, but it feels very important nonetheless.  I want my students to feel the same way.  I am thankful for folks who put math problems up on Twitter because they often reinforce my ideas of what math is, why I love it, and why it’s worthwhile.  Here are a few of my recent favorites (the pictures are links to the tweets):

The #MTBoS Never Sleeps

Is It Harmful or Helptul?

#MTBoS is a community that is filled with diverse knowledge, skills, and resources. Among the resources are rich tasks, the most celebrated being those that involve real world application and mathematical reasoning.

To add to the archive of tasks, recently Robert Kaplinksy posted:

The image of Nelly in a math task was strange on my feed, so I paused to read the tweet, only to feel confused about why we might need to #SaveNelly. I didn’t think much of it, so I scrolled on. Until Hema Khodai replied:


With a single tweet, Hema challenged #mtbos to consider and oppose stereotypes in the tasks we create. While these stereotypes may be subtle, Hema reminds us that we have a responsibility to be critical of the images and notions we normalize in our classrooms of communities that have been historically marginalized.

Rethinking Grading
I work with some wonderful math teachers all over California, and I admire their perseverance and courage. One of the things that I think gets in our way of our good teaching is our attachment to traditional assessments of learning as the primary driving force behind assigning students grades.

I sent out this Tweet to see what folks had to say.


Check out the thread for full details, but here’s what I loved most about my journey down this worm hole of learning.

Rhonda Hewer recommended Aleda Klassen‘s blog “Pedagogical Patterning.” It’s an insightful resource for many reasons and you should check it out. In particular, I dig this post about how we can better listen to our students. She builds upon Max Rey-Riek‘s Ignite Talk from a few years ago title “2 > 4.

Dave Martin writes about his experience removing grades from his high school calculus class in this blog post. He made this stand a few years ago: “I will only assess in a way that increases learning; if my assessment isn’t increasing learning then the assessment needs to change.” Read the post to find out more.

Sunil Singh offers this post on Medium making an argument for how abolishing our traditional notion of grading is the first step to better assessment in mathematics.

If you want to get your academic groove on, Anna Blinstein offers this insightful research article entitled “Teaching More by Grading Less (or Differently).

Geoff Krall gave a brilliant ShadowCon talk about this topic not long ago. Give it a watch and let us know what you think.

Again, check out the thread to see what everyone else said. Thank you to those who helped us further our thinking.

Stay nerdy my friends!
