Four vertical two-digit subtraction problems anchor this sheet: 72 minus 36, 85 minus 47, 64 minus 29, and 91 minus 58. A boxed rule at the top explains the inverse relationship between subtraction and addition, with a worked example showing 63 minus 28 equals 35, checked by confirming 28 plus 35 equals 63. Each problem comes paired with a labeled Check space where your student writes the corresponding addition equation and confirms the sum matches the minuend. This checking subtraction with addition worksheet is designed for 3rd grade and sits naturally in a unit on number relationships or arithmetic accuracy.

For homeschoolers, the two-step format builds a habit of self-monitoring rather than just producing answers, which makes it well suited for independent practice after you have introduced the concept together. Your student practices two-digit subtraction with regrouping and then immediately applies inverse operations to confirm each result. Completing the sheet takes most 3rd graders around ten to fifteen minutes, making it a tidy warm-up or end-of-lesson checkpoint.
