Find the Minuend Answer Key

This worksheet provides 30 problems where the first number (the minuend) is missing, and students must determine what value subtracts to the given result. The problems mix tens and small triple-digit numbers, offering balanced difficulty. This structure encourages deeper reasoning about how subtraction equations can be rebuilt. The repetition builds fluency while still challenging students to think critically. Teachers can use this worksheet to reinforce algebraic modeling or number-line strategies. Students strengthen reversible thinking by reconstructing each starting number.
