Denominator Dice Derby

Denominator Dice Derby is a Grade 4 fraction game for adding and subtracting fractions with a common denominator. Players choose one denominator for the game, roll dice to create numerators, and decide whether each fraction should be added or subtracted as they try to land exactly on a whole. The choices make fraction computation part of a running strategy rather than a set of disconnected problems.

Use it for partner or small-group practice when students understand like denominators and are ready to reason about totals. Listen for estimation around how close a player is to one whole and why adding or subtracting makes sense. Generate the lesson for Denominator Dice Derby with a free Find a Math Game account.
