A very simple but entertaining game to practice basic addition.
Divide the classrom in pairs of students, give each pair a copy of the worksheet and two dice.

How to play:
1. Player 1 rolls two dice. He or she adds the numbers together to find the sum. Player 2 does the same. Circle the math fact with the highest total. The player with the highest total wins the round.
2. Play all 15 rounds. The player that wins the most rounds, wins the game.
