Narrative
Students take turns rolling a number cube and using the number as a numerator in a fraction with a denominator of 2, 3, or 4. Students move their centimeter cube that interval on one of the shared number lines. Each time a cube lands exactly on the last tick mark of one of the number lines, the player who moved it keeps the cube and puts a new cube on zero on that number line. The first player to collect five cubes wins.
Additional Information
Each group of 2 needs 12 centimeter cubes.
