This year I've started teaching a school level Calculus class and it's been so much fun to delve back into some Pre-Calculus topics that I don't normally get to review with my AP kids. This activity was a great review for my students to get them talking, factoring, and thinking. It didn't take long, but generated some good conversations. It would also be a fun extension to have students write one of these "Who Am I?" activities, which could be used for any topic in any course!
