Base Ten Block Addition with Regrouping
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.
“Addition using base ten, partial sums, and regrouping for struggling learners”
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.
