## Proportional Reasoning by Jumping Rope

This lesson write-up is for teaching 6th (and 7th) grade proportional reasoning skills (6.RP.1, 6.RP.2, 6.RP.3) using Graham Fletcher’s Rope Jumper lesson. The write-up contains a lesson pathway with specific questions/moves to consider, analysis of the opportunities for student learning, and other wisdoms and insights we learned from teaching this lesson as a part of a lesson inquiry.

Give it a try with your own students. And then tell me how it went. Let’s get better together.

## Video of Think Like A Fitbit: Measure What We Value

Here’s a link to Think Like A Fitbit: Measure What We Value, my Ignite! talk from CMC South given November 4th, 2016 in Palm Springs.

Feel free to download and share with others. I’m particularly curious how you are able to use this video in your own PD sessions with teachers to further professional growth for all math educators. What conversations does it create? What cognitive conflict does it spark? What change and instructional shifts does it inspire?

Comments are encouraged; feedback welcomed. Let’s keep the dialogue going.

## Think Like a Fitbit: My Ignite! Talk Resources

Welcome back math nerds! And if you’re new to Undercover Calculus, WELCOME! I gave an Ignite! talk at the California Math Council’s conference in Palm Springs. It was called “Think Like a Fitbit: Measure What We Value.” It was an honor to be asked to speak, and I was grateful for the opportunity.

It’s challenging to frame an inspiring argument with enough specific detail so that the call to action is, you know, actually actionable.

So, if you came to my talk and want to know more about these ideas, here are some resources. I hope they further your thinking as much as they’ve furthered mine. If you missed my talk, fear not! I’ve attached a recording of the slide show and attached the movie at the end of this post. Just scroll down. Or you can stream the video of my actual talk on Vimeo.

## Think Like A FitBit: Measuring What We Value

Welcome back math geeks!  Dusting off the old blog to share some of what I’ve been thinking about. I spent the summer asking math teachers the following question:  At the end of the school year, how do you want your students to feel about themselves as mathematical thinkers?  In other words, imagine asking your students: …

## The Powerful Phrase: “…in a way that makes sense to you.” (Part 1)

I had the opportunity to work with several K-5 instructional coaches last week during a one-day workshop on increasing student engagement and discourse in the math classroom.  (My favorite workshop to lead!)  Leadership in the district is making a focused effort to support teachers in their practice of creating classrooms where Math Practice 3 thrives and students are …
