Similar to my hit game "Making 10- a 4 Corners Game". This game is called “4 corners”. 1. Hang up the numbers 1-4 on four corners of your classroom. 2. Cut the cards numbered 16, 17, 18, and 19. Shuffle the cards. 3. Give each student a card numbered 16, 17, 18, or 19. 4. Students have to figure out- how many more to make 20? 5. Go to the corner with the answer to make 20. 6. Shuffle cards and play again. This is an excellent game to play to reinforce addition up to sums of 10 as well as
