Math Tic-Tac-Toe
• Standard tic-tac-toe board.• The active team chooses a square; the question is
revealed• The active team has 15 seconds to decide to keep it, or

seconds to solve it.• If you answer correctly, you gain control of that square.• If you answer incorrectly, the other team gains control
of that square.
