Happy Thanksgiving week to all from the GMD Newsletter teams!

No meeting this week, so why not check out a recording from the archives of one you might have missed?

Last week, Anna Weltman presented Seeing Stars: Using Art to Spark Investigation in Math Class. Check out the recording here.

Things to Check Out

Remote Conferencing: Be Less Jealous!


This year at NCTM Regionals it seemed that #MTBoS was taking over…

However, I was assured that it may just be my twitter lens and that #MTBoS still has a lot of work left to do…



For those of us who couldn’t make it to NCTM: Nashville this year, where the #MTBoS take-over was burgeoning, a new resource was provided by some valiant #MTBoS-ers, like Mike Flynn and Pam Wilson



Periscope is an app that allows users to live stream video and save it for up to 24 hours.  So if you miss a session or aren’t at the conference at all, Periscope can provide an opportunity to engage in a new way.  The only thing is the 24 hour window, to which Mike and Pam have sought an answer. Katch will store user’s live-streamed videos seemingly indefinitely.  

Finally, here is an open google doc started by Michael Pershan including his (and many other’s) thoughts about the NCTM conference experience.  This maybe yet another way for those not at a certain conference to engage with those were there.

Quack and Count


I remember Graham Fletcher recently shared at Twitter Math Camp how interesting a conversation can be that revolves around students understanding (or misunderstanding) the equal sign. That’s why Marilyn Burns’ post, The Equal Sign: What It Really Means, caught my eye. The post is an excerpt from her fourth edition of About Teaching Mathematics., where she uses the children’s book, Quack and Count by Keith Baker.


My favorite part is Marilyn saying, “The equal sign, however, is a relational symbol, not an operation symbol.”

Read more. It’s a quack read. How do your students understand the equal sign?

It seems only appropriate during Thanksgiving week to talk about One Good Thing. If you’ve not seen this site before or if it’s been a while since you checked it out, head on over and scroll through some posts for thoughtful reflections on teaching days, humorous anecdotes from the classrooms, and tales from grading purgatory.
