2-Digit by 1-Digit Multiplication Practice with Area Models
By Kevin H.
A practice packet for 4th graders that builds 2-digit by 1-digit multiplication with regrouping through area model diagrams and the standard algorithm. It moves from guided, pre-drawn area models into independent problems, with step-by-step worked examples that show how partial products are decomposed and added.

Teacher Guide & Tips
- Use as a 45-minute math block, starting with the worked example for 24 × 3 as a whole-class demonstration before students move into guided practice.
- Discussion question: Why does breaking 24 into 20 + 4 give the same product as multiplying 24 directly, and how does the area model show that?
- Scaffold for struggling readers and learners: have students label each partial product on the diagram before adding, and use base-ten blocks to represent the tens and ones alongside the drawing.
- Extension for advanced students: ask them to solve a problem both with the area model and the standard algorithm, then explain how the regrouped digits match the partial products.
- Estimated time: about 30 minutes for guided practice and 15 minutes for independent problems.
