About the Addition with Regrouping Worksheets
Carrying is a big step in grade 2, and practice only helps when every problem actually needs it. On this page each problem adds two two-digit numbers whose ones add up to 10 or more, so students regroup every time, like 38 + 47 or 56 + 29, and the sum always stays under 100. The problems are stacked vertically and right-aligned so tens sit over tens and ones over ones, with room above for the little carried 1. Switch to Within 100 without regrouping to build confidence first, then come back here.
Ways to use regrouping worksheets
Before and after
Print one page without regrouping and one with it, and talk about what changes when the ones add up to 10 or more.
Base-ten blocks first
Solve the first row with the Base-Ten Blocks in Math Manipulatives, then finish the page on paper.
Error hunt
Use the answer key to find the first wrong answer and ask students to explain what went wrong.
Spiral review
Print a short 12-problem page once a week after the unit so carrying stays fresh.
Frequently Asked Questions
Does every problem need regrouping?
Yes. The ones digits always add up to 10 or more, so each problem carries one ten.
Can the sum go over 100?
No. Both numbers are two-digit and the sum always stays below 100.
