'40 + 20 = 60' is the same as '4 tens + 2 tens = 6 tens' and we know '4 + 2 = 6'.
We will also begin to understand that addition can be done in any order. For example...
'5 + 4 = 9' is the same as '4 + 5 = 9'.

Numeracy - Partitioning numbers.
At the end of last week we learnt about partitioning for example, 37 = 30 + 7 and developed our understanding using place value cards.
This week we will continue to learn about partitioning and begin to use this knowledge to help us with our addition. For example...
'40 + 20 = 60' is the same as '4 tens + 2 tens = 6 tens' and we know '4 + 2 = 6'.
We will also begin to understand that addition can be done in any order. For example...
'5 + 4 = 9' is the same as '4 + 5 = 9'.
'40 + 20 = 60' is the same as '4 tens + 2 tens = 6 tens' and we know '4 + 2 = 6'.
We will also begin to understand that addition can be done in any order. For example...
'5 + 4 = 9' is the same as '4 + 5 = 9'.
