Near doubles worksheet

Part A: Working out and filling in

1. 1. 5 + 6 = 11

   The numbers are one apart, so double and add one: 5 + 5 = 10, 10 + 1 = 11

2. 2. 4 + 5 = 9

   The numbers are one apart, so double and add one: 4 + 4 = 8, 8 + 1 = 9

3. 3. 8 + 9 = 17

   The numbers are one apart, so double and add one: 8 + 8 = 16, 16 + 1 = 17

4. 4. 8 + 7 = 15

   The numbers are one apart, so double and add one: 7 + 7 = 14, 14 + 1 = 15

5. 5. 6 + 7 = 13

   The numbers are one apart, so double and add one: 6 + 6 = 12, 12 + 1 = 13

6. 6. 3 + 2 = 5

   The numbers are one apart, so double and add one: 2 + 2 = 4, 4 + 1 = 5

7. 7. 3 + 4 = 7

   The numbers are one apart, so double and add one: 3 + 3 = 6, 6 + 1 = 7

8. 8. 1 + 2 = 3

   The numbers are one apart, so double and add one: 1 + 1 = 2, 2 + 1 = 3
