For small group or partner play. Students take turns rolling dice (2 for 2-10 and 1 for 1-6), they cover the number of their roll with a counter.. Each student should have a different color counter. I love using unifix cubes for this purpose. If a student rolls a number that is already covered, they can bump off the other counter and claim it with their color. Once two counters of the same color are added to a number, the number is locked and cannot be bumped or added to. The game ends when all numbers are locked.
