These two games will give your students plenty of practice rounding three digit numbers. To allow for differentiation, the first game has students rounding three digit numbers to the nearest ten or to the nearest hundred. The second game simply has students rounding to the nearest hundred.
**Bump is a game for two players. Print and laminate the game boards and answer key. Each pair of students will need two dice and twenty two-color counters (ten for each student).
**Directions: Player A rolls two dice and finds the sum. Find the directions that are next to the sum. Use a marker to cover the rounded number on the Game Board. Player B takes a turn.
If the number already has a marker on it, the player can BUMP the marker off of the board and replace it with his/her own marker. Once a player has put two markers on a space, the space is LOCKED and markers can no longer be BUMPED. The player who places all ten markers on the Game Board first is the winner!
**Included in this file are two bump games with keys for students to use to check answers. These games are fun for practice, for review, as work for early finishers, and as math centers.
