I use this game with my first graders to practice the commutative property of addition, or "turn around facts". Students take turns flipping over two cards and try to make a match. However, in this version, students are looking to match basic math facts with their turn around fact in order to increase basic fact fluency. Of course, students need to find the sum before getting to keep the cards! My kids love this game and I hope yours will, too. Simply print onto card stock, laminate, and enjoy!
