# ZERO!

I invented a new game for factoring quadratic trinomials over the summer break. After waiting to get to quadratics, I'm excited that this week I was finally able to play it with my Algebra 2 classes. As I was planning, I was thinking about how to motivate teaching factoring. In particular, I was inspired by Dan Meyer's thoughts, where he mentioned that locating zeroes is the key problem that factoring helps solve. I decided to find a way to make finding those zeroes the focus of how I introduced this topic. This game, which I'm calling "ZERO!" is about evaluating expressions and finding zeroes. Students are in groups of four, and each group receives a set of 36 cards with a range of expressions on them. Most are quadratic trinomials, but there are some linear expressions, quadratic binomials and a handful of factored quadratics. As a warm-up, I had students...
