Double-Digit Addition and Subtraction with Regrouping for 2nd Grade
A 20-problem practice set that helps 2nd graders add and subtract double-digit numbers with regrouping, with horizontal problems and room to rewrite each one vertically. It opens with a short step-by-step guide and a worked addition example, and it pairs well with base-10 blocks for checking work.
“add and subtract d ouble digit with regrouping harizontally and space to rewrite vertically, 20 problems”
Teacher Guide & Tips
- Use this as an independent or partner practice block of about 20 to 30 minutes after a mini-lesson on regrouping, or as a station activity during math rotations.
- Discussion question: When you add the ones and get 12, why do we write the 2 and carry the 1 to the tens place?
- Scaffold for struggling readers: Have students build each problem with base-10 rods and cubes first, then copy it vertically before solving, and read the four steps aloud together before starting.
- Extension for advanced students: Ask them to create their own double-digit problem that requires regrouping in both columns, then check it with a model.
- Estimated time: About 2 minutes per problem, so roughly 30 to 40 minutes for all 20 problems including the vertical rewrites.
