Make a game out of math with this worksheet featuring a race to 100! In this Hundreds Chart Game, players will take turns rolling two dice. Then, they'll move up and down the chart based on the sum of the numbers they rolled, but they'll need to be on the lookout for rain clouds and rainbows that might send them backward or nudge them forward. The first player to reach the sun (100) wins! This game is a great way to help first grade learners hone their addition and subtraction skills.
