Partitioning to add
Some of us this week have been partitioning numbers to help us add 2 2 digit number together. We have also used diennes to help us see the value of each number.
Diennes 
We use the diennes above so children have a visual representation of numbers and can see their value.
The yellow cubes-= 1
The green sticks =10
The blue squares = 100
The red cube = 1000
This is how we have been recording our work this week:
40+20= 60
7+5=12
60+10=70
70+2=72
