Easy prep! Just print and play! This Multiplication Bump game is a great way to practice math facts through 12s. All you need is 2 students, a game board, 20 tokens, and 2-twelve sided dice or 4 regular. Students roll both dice, multiply the two numbers together (or if you use four, they roll all 4, add two up and multiply the sums together) and if their answer is on the game board, cover it with one of their tokens. If the answer is already covered, you can bump the other player's token off the board. Unless, it's stacked 2 high! Then it's locked and can't be bumped. This set includes 5 different game boards.
