This week in Maths we have been learning to add on the blank numberline.
To help us secure this skill and improve our mental calculation skills we need to be able to quickly add and subtract numbers to 20.
This week practice adding these numbers. Can your number bonds help you? Are there any other strategies you have.
If you know 10 + 7 = 17 Can you use a different combination of numbers to make the same answer?
e.g 10 + 5 + 2 = 17 5 + 5 + 5 + 2 = 17 11 + 2 = 17
