Fluency in Addition and Subtraction.
If children are able to recall or quickly work out simple addition and subtraction facts they will be flexible and confident in their use of number at all levels.  Once they know or can quickly calculate these facts they can work out new and more complex problems.  In Year 1 and 2
we teach strategies for facts within 10 (steps 1 – 7) and in Year 2 we teach the bridging ten facts (steps 8 – 11).  Try using dominoes or cards to practice the simple addition and subtraction facts on this page.

1. Adding and Subtracting 1 (e.g. 7 + 1 and 1 + 7)
2. Doubles and near double of numbers to 5 (e.g. 3 + 3, 4 + 5, 5 + 4)
3. Adding and Subtracting 2 (e.g. 4 + 2 and 2 + 4)
4. Number bonds to 10 (e.g. 8 + 2, 2 + 8, 10-2=8 and 10-8=2)
5. Adding 0 to a number (e.g. 3 + 0 and 0 + 3)
6. Adding 10 and subtracting 10 from a number (e.g. 5 + 10 and 10 + 5, 13+10, 23-10)
7. 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)
8. Doubles of numbers to 10 (e.g. 7 + 7)
9. Near doubles (e.g. 5 + 6 and 6 + 5)
10. Bridging (e.g. 8 + 4 and 4 + 8, 12-5 and 13-7)
11. Compensating. (I know 37-10 is 27, so 37-9 must be 28)

For home learning this week I would like you to see how many of these you know or can work out really quickly.  Fill in the missing squares on this grid, there are also some quick addition and subtraction facts for you to calculate.
