Last year I wrote about an activity I implemented designed by Steve Kelly in which students complete a card sort task, some whiteboarding, and independent practice. The idea is that this activity is the entry point to trig verification, which can be a tough topic for students. I like a lot of things about it but one aspect that I noticed this year is the benefit of getting students up and moving around. It breaks up the class and I think it’s helps the brain learn (I’m sure I read or learned that somewhere, so if I’m wrong please do call me out in the comments). My reflections are similar to last year so the main purpose of this post is to share some of the images from this year’s activity. As usual, feedback is welcome!
