This is my first year teaching Pre-Calc. However, with the exception of our trig unit (which, granted, is a good portion of the class), I've taught most topics we cover in Pre-Calc. But, today's lesson was on the Binomial Theorem, which I had never taught before. As I was reading up on it, I found myself noticing and wondering. There's so much to explore. At first glance, do a bunch of expansions look all that thrilling? Maybe not. But, the more you dig into it, the more patterns you begin to find. So, I decided to put my students to the challenge, too. This was their warm up today:
I gave them 3-5 minutes. And then I started calling on people to share, writing their thoughts on the board so everyone could see. They were hesitant at first but grew more confident as we went on. After I had called on several kids, I asked if anyone else had something s/he wanted to contribute. These are the lists we made in my two classes:
Mostly, I just wanted to share my students' thoughts, because I thought they did a great job for this first-ever notice/wonder assignment. Also...the second class's "wonder" was, of course, the very nature of the lesson, so...mwah!
