Give students 10 index cards. Have them write one multiplication fact on one and the inverse division problem on the other card. Do this for all ten cards. Divide the class into 4-5 groups. To play, they lay all cards face down on a desk. Then one student turns two cards over. If they are a pair(one multiplication and an inverse division problem) the student keeps both cards. If not, they both get turned over and the next student tries to get a match. Play continues until all cards are gone or no more pairs can be made.
