Today we will be adding by making 10. 

For example: When adding 6 + 7 we would first add 4 to the number 6 to make 10 and then we would add 3 to the 10 to give us the answer 13. This will make more sense when you see the video. 



Children add numbers within 20 using their knowledge of number bonds.

It is important that children work practically using ten frames and/or number lines to help them see how number bonds to 10 can help them calculate. Get them to draw a tens frame or number line and use anything you have to hand that they can use as a counting resource (pasta, buttons, straws, tooth picks...…).   

They will move towards using this as a mental strategy.
