During maths we have been learning about bridging the decade. We learned that when two numbers are added together to become more than ten, twenty or thirty, you can start with the largest number, take from the smallest number, add to the nearest decade and then add what is left of the smaller number to find the answer.
It's quite tricky!
We used unifix cubes to go through the process. You can see some photos below.
