Missing Minuends Answer Key

This worksheet includes 15 problems involving missing minuends in large-number subtraction. Students must add the subtrahend and difference to reconstruct the original value, reinforcing reversible thinking. The problems require strong place-value fluency as students work with multiple columns and frequent regrouping. The page is well-suited for upper-elementary students preparing for more abstract algebraic reasoning. Teachers can use this worksheet for challenge work, assessments, or mastery practice. Students gain deeper insight into how subtraction equations behave when one piece of information is removed.
