3. Mental Maths Learning Objectives I will be able to use a number of different mental strategies to add and subtract.

4. Adding on 22 + 17 = 22 10 32 5 39

5. Adding on 52 + 11 = 52 10 62 1 63

6. Adding on 43 + 15 = 43 10 53 5 58

7. Now you try!

8. Subtracting strategy 43 - 15 = 43 10 33 5 28 58

9. Subtracting strategy 33 - 23 = 33 10 13 3 10

10. Subtracting 73 - 17 = 73 10 63 7 56

11. You can now do it!

12. Mental Maths Learning Objectives I am now able to use a number of different mental strategies to add and subtract.

13. Estimating Main Learning Objective I will be able to estimate objects and numbers accurately.
