Activities
- Tumblin' Dice - It's not easy to find a copy of this game (and a bit expensive when you do), but I really liked this game for mental math as well as probability. If you've got a nice wood shop teacher at school, maybe they could make you a version. Or you could make your own version with styrofoam blocks or stacks of textbooks.
