Multiplication worksheet for practicing multiplication by 1 to 3.

Let me solve each multiplication problem step by step:

1. 7 × 1 = 7
2. 5 × 2 = 10
3. 3 × 2 = 6
4. 11 × 1 = 11
5. 7 × 3 = 21
6. 10 × 3 = 30
7. 12 × 2 = 24
8. 13 × 3 = 39
9. 12 × 1 = 12
10. 1 × 2 = 2
11. 11 × 2 = 22
12. 3 × 1 = 3
13. 6 × 3 = 18
14. 7 × 2 = 14
15. 10 × 1 = 10
16. 13 × 2 = 26
17. 15 × 1 = 15
18. 1 × 1 = 1
19. 6 × 1 = 6
20. 3 × 3 = 9

Let me double-check my calculations:
- Problem 8: 13 × 3 = 39 ✓ (13 + 13 + 13 = 39)
- Problem 16: 13 × 2 = 26 ✓ (13 + 13 = 26)
- All other calculations look correct.
