This turn triangle can be used during the game Beat the Calculator. Students place the triangle in between them so designate their role in the game, either the brain, the caller, or the calculator.
In case you have never played this game, here's how to play:
The caller uses a math fact reference sheet to call out a math fact.
The brain solves the math fact in their head.
The calculator must use their device to compute the answer.
Whoever calls out the correct answer first (as checked by the caller) wins!
After every 10 facts (or another number to your choosing), rotate the triangle to change jobs.
