1. Primary Maths Calculation Strategies

2. Addition

3. 1 2 3 4 5 6 7 8 9 10

4. 3 and 2 more

5. Recording number sentences 5 + 2 = 7 7 = 5 + 2 5 = 5 1 + 4 = 2 + 3

6. Partitioning 36 + 45 = 30 + 40 + 6 + 5 = 70 + 11 = 81

7. 23 + 14 = 37

8. 45 + 31 = 76

11. Subtraction

12. 1 2 3 4 5 6 7 8 9 10

13. 2 less than 5

14. No Partitioning 73 – 26 = ?? well 70 – 20 = 50 but 3 – 6 ???

16. 123 – 89 =34

17. Multiplication 6 x 3 = 18 and 3 x 6 = 18

19. Partitioning 23 x 5 = 10x5 + 10x5 + 3x5 = 50 + 50 + 15 = 115

21. Division
