Stand up and Ponder (routine?). I make the AP CS Principles kids get up and talk through random puzzlers together. Making the kids talk really helps their future williness to ask their peers for help. Today was just someone next to them, in the future the groups will be randomly selected. #photo180

I have a strong opinion that the vast majority of Desmos (like) computer activities should be done with 2 or 3 people per one computer. You can’t hear it in a photo (duh) but the class is buzzing with math conversation. Day 2. #photo180
