Join Dan Finkel, founder of Math for Love and nationally recognized mathematics educator, for an inspiring keynote session titled "How Mathematicians Play." Play is one of the most effective ways to explore new ideas. But play without thoughtful structure won’t help us to achieve our teaching goals. We need boundaries and strategies to promote meaningful exploration and help students develop true mathematical understanding. By looking at how mathematicians play, we can offer students an invitation to genuine mathematical thinking and ownership. We’ll explore some specific routines and tools, particularly conjectures and counterexamples, that can transform classroom culture and make rigorous, joyful play a driving force in math class.
