Circles Intro Desmos Polygraph

In my Honors Math II class I frequently am saying (both to my colleagues and my students) that we have so so so many topics to cover. It leads to a lot of boring days, in my opinion, of notes-practice-notes-practice-notes-practice blah blah blah. My learners don’t really complain – most have been in the honors track for a while and that’s kind of how it’s always gone for them. I do switch up how they practice and review and have done my fair share of discovery and VNPS activities, so I shouldn’t say it’s all the same. But we’re now on our last unit of the semester and it’s all about circles. The vocabulary that starts off this unit can be a bit overwhelming and we were starting this coming off two days of MAP testing and lost a day of the unit to a snow day, so I really wanted something engaging and meaningful that wouldn’t burn a lot of time. After asking the #MTBoS, I answered my own question with doing a Demos Polygraph activity. I edited one I had found from Burt Dixon to fit my introduction vocab a little better. Here it is:

It went really well! The kids really enjoyed it and were fully into it the whole time. I happened to end up with my evaluator in my room during it and she was really impressed, too. After the class was getting to the point where most were winning in 2-4 questions, I had them all draw a circle so we could put some of the things they noticed into formal vocabulary. So not only did I plan an engaging lesson, but I also didn’t skip the close! The best part was that my learners and I can now reference the Polygraph activity as we’re learning more things about circles. 🙂

I also got some other ideas from the #MTBoS about other discovery tools for circles that I would definitely do if I had more time. Check out my post on Twitter to see them.

Et encore, j’adore Desmos.
