Students love dueling math facts. It’s a fun and exciting way for children to learn subtraction facts. Stack cards in the middle of two players. Players take turns flipping over the cards and giving the answer to the problem. If there is a tie I tell my students to play rock paper scissors to see who keeps the card. Winner of the game is the player with the most cards.
I also like to play whole group and sit half of the students facing the other half. Basically I have two rows of 9 and the math partners are face to face. I have a side A and a side B. We see which side can earn the most math facts. I put around 6 cards in the middle of each set of two students. When I say DUEL students duel. Once all cards are used, we stop and count the cards for team A. Next we count the cards for team B. I keep track then we pass the stack once to the left and continue to play. Sometimes we say whichever side has the most points lines up first or something simple.
