Align with the Common Core State Standards in Mathematics and the Mathematical Practices. The students will be solving addition problems mentally. This activity is played in groups of 2. Each player places a paper clip on the numbers across the bottom of the page. Then, player 1 gets to claim the sum of the 2 numbers by placing a BINGO chip on the sum. Player 2 gets to move 1 of the 2 paper clips at the bottom and then captures the sum of the 2 numbers by placing a BINGO chip on the sum. Play continues until 1 player has 4 chips in a row, either up and down or diagonally.
