This next game I use throughout the year, too. It actually requires minimal prep, but it is really easy. I create a grid in Word with letters along the left and numbers on the top. Typically, I will letter it A-H and number it 1-8. I will project the grid, and then I print a copy for myself. On my copy, I write down numbers 10, 20, 30, 40 and 50 in all of the different empty squares.
During the game, I ask students questions. When they answer correctly, they can choose a square. I look on my grid to determine if they will earn 10-50 points. This keeps the game exciting because a group can jump into the lead if they “discover” a 50 point square! The students enjoy it, and they love trying to pick their square.
