Max Rescues the Jazz Club: Addition Regrouping Race

About this Grade 2 Addition With Regrouping Drill

Addition with regrouping—sometimes called "carrying"—is a landmark skill that bridges what second graders learned about place value in first grade to real multi-digit computation. By age 7 or 8, children's brains are developmentally ready to hold two pieces of information at once: the ones place and the tens place. This skill is essential because most everyday math involves numbers larger than 10. When your child buys two items at a store, counts allowance, or combines groups of objects, regrouping happens naturally. Mastering it now builds confidence and prevents the frustration that can arise when struggling students fall behind in third grade. It also strengthens number sense—children begin to truly understand what "10" means as a unit, not just a symbol. This worksheet provides focused practice so regrouping becomes automatic and stress-free.

What your student will practice

• Add two-digit numbers with regrouping from ones to tens place
• Recognize when the ones column totals 10 or more
• Correctly "carry" the tens digit and add it to the tens column
• Write answers in the correct place-value positions

Common mistakes to watch for

The most common error is forgetting to add the regrouped ten to the tens column—a child might get 15 in the ones place, write down the 5, but then ignore the 1 and just add the original tens digits. Another frequent mistake is writing both digits of a two-digit sum in the ones place (like writing "15" instead of "5" in the ones column). Watch for careless errors where a child forgets to regroup even when they see 12 or 13 ones. If your student consistently adds correctly but struggles with the "carrying" step, they likely understand addition but need explicit practice with place-value language: "We have 13 ones, which is 1 ten and 3 ones."
