This is a Memory game to help students understand adding using the commutative property of addition (ex. 3+4 and 4+3) as a mental math strategy. Each page has 8 cards (a total of 32 cards). You will need to cut out the cards along the black lines. Each card has a commutative property 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 and solve the addition problem. If you have a matching commutative property facts (ex. 3+4 and 4+3), you will keep the pair. If you do not have a matching commutative property facts, play moves on to the next player.
The player who has the greatest number of matching commutative property facts pairs will win!
