This week we have been investigating number bonds to 10 and 20. You can listen to this song to improve your recall of your number bonds. How quickly can you say all of your number bonds to 10?
We looked at making addition and subtraction number sentences from these number bonds.
E.g 1+9 = 10 9+1 = 10 10 – 9 = 1 10 – 1 = 9 We called these number families, where we use the same 3 numbers to make 4 different number sentences.
Can you use your number bonds to 10 to help you record number families for numbers to 20?
*Challenge* – You could use your number bonds to help you record number families for numbers to 30, 40 or maybe 100.
