Lesson

8th Grade Math - Representing Constant Rate of Change

Clip 9/18: Lesson Part 2A

Overview

Antoinette Villarin’s students return to their groups to discuss and share their thinking about the relationship between graphs showing rate of change. She challenges them to try to find the two graphs out of four with the correct combination to describe the same container. As the student partners work, Antoinette circulates around the room engaging pairs in questioning.

Teacher Commentary

It's hard when you're walking around and you can’t hear every student pair. I appreciated the videotaping. The videotaping allowed me to observe student thinking from the opposite end of the room. Normally, when I can’t observe every pair, I have to be attuned to what students are saying. Things like “This is too hard” or perceived difficulties remind me to check in with those students eventually.
