Missing Digits

This worksheet provides 30 single-digit column subtraction problems with missing values in various positions. Students must determine which digit completes each subtraction equation, reinforcing early place-value understanding. Because the numbers are small, learners can focus on logic and structure rather than computation difficulty. The boxed format provides clear scaffolding that helps students check each column carefully. This worksheet is ideal for beginners, intervention groups, and fluency warm-ups. Students strengthen foundational subtraction reasoning by identifying which number creates the required difference.
