Base Ten Block Addition with Regrouping
By Amanda A.
A practice set for 2nd graders that builds two-digit addition using base ten blocks, with worked examples showing how to trade 10 ones for 1 ten. Students match addition problems to block pictures, strengthening place value understanding and regrouping skills for learners who need extra support.
Customize for your classroom
Teacher Guide & Tips
- Use this as a small-group intervention or a 20 to 30 minute math station, pairing it with physical base ten blocks so students can physically trade ten ones for a ten.
- Discussion question: Why do we trade 10 ones for 1 ten, and how does the total change when we do? Ask students to explain 28 + 15 using their own words before they look at the answer.
- Scaffold for struggling readers: Read the directions aloud, model the first matching problem with blocks on the table, and let students point to the tens and ones before drawing any lines.
- Extension for advanced students: Have them create their own two-digit addition problem that requires regrouping, then draw the block picture to match it.
- Estimated time: About 25 minutes for the full practice set, plus 5 minutes for a quick class check of answers.
