Across Years 1 and 2, the children will be taught a range of strategies to ensure they are fluent in their recall of addition and subtraction facts. By our children becoming fluent in the following facts this will allow the children to tackle more complex maths more effectively.
Year 1 we teach strategies for facts within 10 (steps 1 – 7) and in Year 2 we teach the bridging ten facts (steps 8 – 11).
- Adding 1 (e.g. 7 + 1 and 1 + 7)
- Doubles and near double of numbers to 5 (e.g. 3 + 3, 4 + 5, 5 + 4)
- Adding 2 (e.g. 4 + 2 and 2 + 4)
- Number bonds to 10 (e.g. 8 + 2 and 2 + 8)
- Adding 0 to a number (e.g. 3 + 0 and 0 + 3)
- Adding 10 to a number (e.g. 5 + 10 and 10 + 5)
- The ones without a family 5 + 3, 3 + 5, 6 + 3, 3 + 6 (these pairs of facts are the only ones which don’t fit in any of the other families, though the last two can be related to counting in 3s)
- Doubles of numbers to 10 (e.g. 7 + 7)
- Near doubles (e.g. 5 + 6 and 6 + 5)
- Bridging (e.g. 8 + 4 and 4 + 8)
- Compensating
Once children have been taught the strategies, they need to move on to practising their recall of these facts. For many facts, the aim is memorisation, while for others is to recall with speed and fluency in the applied strategy.
