These cards are intended to be used with Subtraction BONGO 1-10. Print off cards onto cardstock, cut apart, laminate and cut apart again. The adult in charge calls out a subtraction fact. Students mark the answer on their 5 x 5 square on their game sheet. The first player to get five in a row either across, down, or diagonally is the winner. I generally give a small prize like a pencil or piece of candy.
