If, conceptually, pi is something you need to revisit (can’t tell a Euclidean plane from a delayed flight on Delta?), I can’t help you out.
But if you just want a trick to perform at tonight’s Pi Day party (what? You and the kids weren’t invited to one?), I’ve got what you need right here.
Hooda Math, a really cool math games website — developed by a former middle school math teacher — put up a game especially for today, Pimon. It’s like Simon (where you memorize a sequence of colors) but with numbers.
Easy. Addictive. But educational!
After just a few minutes on Pimon, I’m already up to 3.14159265. (Please, no quizzes tomorrow.)
