Tackling Add & Subtract uses exactly the same principles and approach as Tackling Tables – this time to help children develop confidence and fluency in mental addition and subtraction.

Using the following National Curriculum expectations, it uses colour coded cards to help children develop a range of skills. Each phase builds on the previous one to extend their thinking.

- Recognising number bonds to 10 e.g. 3 + 7 = 10
- Adding doubles within 20 e.g. 6 + 6 = 12
- Adding near doubles within 20 e.g. 8 + 9 = 17
- Adding single digits within 10 e.g. 7 + 1 = 8
- Adding single digits to bridge 10 within 20 e.g. 9 + 6 = 15
- Adding and subtracting zero
- Adding 10 to a single digit e.g. 10 + 3 = 13
- Using the inverse to subtract

- Recognising number bonds to 20 e.g. 14 + 6 = 20
- Adding multiples of ten to make number bonds to 100 e.g. 20 + 80 = 100
- Adding double digit multiples of 10 e.g. 40 + 40 = 80
- Adding a double digit to a single digit without bridging e.g. 42 + 7 = 49
- Adding a double digit to a single digit to make a multiple of 10 e.g. 21 + 9 = 30
- Adding a double digit to a single digit to bridge a multiple of 10 e.g. 86 + 7 = 93
- Adding a multiple of 10 to a double digit e.g. 30 + 18 = 48
- Using the inverse to subtract

- Adding a double digit to a double digit without bridging e.g. 28 + 41 = 69
- Adding a double digit to a double digit to make a multiple of 10 e.g. 33 + 47 = 80
- Adding double digit to a double digit to bridge a multiple of 10 e.g. 55 + 18 = 73
- Recognising double digit number bonds to 100 e.g. 24 + 76 = 100
- Using the inverse to subtract
