Build a Subtraction Problem

Build a Subtraction Problem is a Grade 4 game about constructing a valid subtraction equation from digit cards. Players fill positions in a subtraction form as digits become available, working toward a complete problem while respecting the restrictions built into the board. Because each placement affects what can happen later, students have to think ahead about place value and the structure of subtraction.

Use it in a small group after students have learned multi-digit subtraction and are ready for more strategic practice. Completed equations can be checked by the other players, creating a natural reason to verify both the setup and the computation.
