Now that pupils have a good understanding of what addition is and of place value, they can apply this to represent addition of larger numbers using column addition. They have the understanding needed to explain how this representation works and have the opportunity to apply this to find missing values, applying their understanding of parts and wholes or addends and sums. Pupils also use other known strategies to estimate and check their calculations.
Prior knowledge requirements
- Recall number bonds and addition facts within 20
- Use place value knowledge to add 2- and 3-digit numbers
- Understand and use column layout for addition
