This product contains two separate games. One is addition memory. In this game students play the traditional memory game by matching number sentences with equal sums. Doubles facts are included as well as other math facts 0-20. The other game is a subtraction memory game. This time students match pairs with equal differences. These cards could also be used for other activities in class where students could be asked to pair up by finding another friend with the same sum/difference, or a game of go fish. A recording sheet for all pairs is included in this product as well.
