You can run the cards off on cardstock, cut to size, and laminate them for a permanent game solution. You can also run them off on paper and have the students cross off the answer as they solve the problems.
The game can be played by small groups at a center. I included blanks that students have used to create questions and boards.
Based on your allowed time, you can play five in a row, just the corners, or cover the whole board.
