Inspiring Stuff, November Edition

Welcome back Math Geeks!

In this week’s Global Math Department newsletter, I wrote about some stuff (activities, resources, writing, thinking) that I found useful, inspiring, and worth sharing.  I’d like to share a few of them with you here. There’s some Desmos stuff and some pondering about place value stuff. There’s some questioning stuff and student discourse stuff. There’s also other stuff and it’s all inspiring stuff. Let’s get started.

“We’re Gonna Need a Different Denominator”

Check out this compeling video from Andrew Stadel. What do you notice? What do you wonder? How can this be used to teach students about adding fractions?

I conducted a lesson study about fractions with some 5th grade teachers.  We used Andrew’s elegantly simple lesson called Black Box 2 to get students talking about adding fractions with unlike denominators.  This task is ideal for introducing the intellectual need for finding a common denominator before adding fractions procedurally.  Student discourse is rich and meaningful and lively.  Give it a read.  You won’t be disappointed.

Make Lesson Study Meaningful

I had the opportunity to give a talk at CMC-South earlier this month about my work conducting lesson studies.  About 40 inspiring educators showed up to geek out with me and learn about ways to generate teacher buy-in so that teacher learning made during lesson study leads to lasting professional growth.  This post contains a quick outline of part of my talk and the resources I shared with participants.  Please feel free to use the resources in your own work conducting lesson study.  I’d love to hear feedback.  Let’s get better together.
