Two-digit multiplication

What they’re learning

Your child is multiplying two-digit whole numbers using area models, partial products, or efficient algorithms. Understanding the partial products helps prevent place-value errors.

Explain it to my child

For 23 × 14, break 14 into 10 + 4: 23 × 10 = 230 and 23 × 4 = 92. Add them to get 322.

Try it together

Draw rectangles on grid paper for problems such as 18 × 24. Split 24 into 20 + 4 and label each partial rectangle before adding the areas.

Practice

1. 24 × 13 = ?
2. 36 × 21 = ?
3. 45 × 12 = ?
4. 19 × 22 = ?
5. Estimate 61 × 39 before calculating.

Check understanding

• Can your child explain where each partial product comes from?
• Can they use an estimate to catch a misplaced zero or unreasonable result?
