This year on Pi Day I was teaching exponents, so I created an activity surrounding many of the common errors that I see many students make when working with expressions involving exponents. I have attached the file to this post, and I would hope that people would know what to do with it, but let me explain anyway:

1. I printed and cut out about 10 copies of the activity (I wanted to have the students work in groups of no more than 3). I also like to have 1-2 extra copies because it has become seemingly noticeable with my classes that there are some students who like to take the activities home with them. Honestly, if a simple game like this gets them excited enough about math that they actually want to do play math again when they get home, I’m all for it. By the way, it worked out best for me to place the cut out pieces in 10 separate envelopes.
