Use these cards to help your students practice their math facts. Print out cards and cut. Then hole punch on the top left corner and place on a ring. Students will work with a partner. One person will hold the ring and turn the cards as the other student answers. If they get stuck the student turning cards can help, or they can use their reference chart. When they flip a BOOM! card, then they switch roles. Simple game, but the kids love it. Use it at the beginning of class for 3-5 minutes
