The formal method of addition is an important part of Year 3 work. Children will be expected to add two 2-digit numbers, including exchanging 10 ones for 1 ten. They will then progress to adding a 2-digit number to a 3-digit number and then adding two 3-digit numbers.

Our step-by-step tutorials are excellent at showing all the stages in completing a written addition. They can be played time and time again, until children are completely happy with the approach.
