Part A: Working out and filling in

1. 1. 4 × 7 = 28

   4 × 7: ×4 is double, then double again, 7 × 2 = 14, 14 × 2 = 28

2. 2. 3 × 1 = 3

   3 × 1: times 1 leaves a number as it is, so it's 3

3. 3. 12 × 4 = 48

   12 × 4: ×4 is double, then double again, 12 × 2 = 24, 24 × 2 = 48

4. 4. 4 × 8 = 32

   4 × 8: ×4 is double, then double again, 8 × 2 = 16, 16 × 2 = 32

5. 5. 3 × 4 = 12

   3 × 4: ×4 is double, then double again, 3 × 2 = 6, 6 × 2 = 12

6. 6. 3 × 9 = 27

   3 × 9: ×3 is a double and one more, 9 × 2 = 18, 18 + 9 = 27

7. 7. 4 × 5 = 20

   4 × 5: ×4 is double, then double again, 5 × 2 = 10, 10 × 2 = 20

8. 8. 12 × 3 = 36

   12 × 3: ×3 is a double and one more, 12 × 2 = 24, 24 + 12 = 36

9. 9. 4 × 6 = 24

   4 × 6: ×4 is double, then double again, 6 × 2 = 12, 12 × 2 = 24

10. 10. 3 × 7 = 21

    3 × 7: ×3 is a double and one more, 7 × 2 = 14, 14 + 7 = 21

11. 11. 5 × 3 = 15

    5 × 3: ×3 is a double and one more, 5 × 2 = 10, 10 + 5 = 15

12. 12. 4 × 4 = 16

    4 × 4: ×4 is double, then double again, 4 × 2 = 8, 8 × 2 = 16
