Students had a week to design a poster board that was complex enough to make their proof interesting and challenging. While proof writing may not seem like an inherently creative pursuit, students clearly enjoyed developing designs, with the corresponding statement and reason columns, inspired by Hanukkah, Christmas, and Chinese New Year. “It's fun because they've had the aha moment,” says Janet. “Instead of just being given information, they now know how to create it and provide just enough information to lead someone to what they want to prove. It’s tricky, but they have made that leap.”
