This is a Memory game to help students understand adding doubles as a mental math strategy. Each page has 8 cards (a total of 24 cards). You will need to cut out the cards along the black lines. Each card has either a doubles fact or a sum. There is a matched sum for each doubles fact.
Directions for Play:
First, shuffle the cards and lay them face down on the table.
Students will take turns playing. The player whose last name comes first in the alphabet may start and then play will move to the right.
When it is your turn, turn over two cards. If you have a matching doubles fact and sum (ex. 2+2 and 4), you will keep the pair. If you do not have a matching doubles fact and sum, play moves on to the next player.
The player who has the greatest number of matching doubles facts and sums will win!
