Today we were learning number bonds for 20 using what we know about number bonds for 10. We used the numicon materials to visually represent the numbers and we could see that 20 is made up of 2 ten tiles which can be broken up into 2 numbers such as 10, 8 and 2, which we write as 18+2=20. We worked in pairs using numicon to explore all the different ways to make 20.
