This is a cootie catcher that uses single digit double addition facts. This would be great as a center to reinforce facts. Students could do the activity individually or as partners. As partners, one is the holder and one the player. The holder holds and moves the catcher. The player chooses a number, then the holder opens and closes the catcher the number of times as the number was chosen. Then, the player chooses and answers a math fact shown. The holder checks the answer. If correct, partners switch who's holding the catcher. If incorrect, the player tries again.
