£2.99
SKU M3IL30084
Key Stage 2 Maths Year 3

This lesson leads them from the informal vertical partitioning method to the expanded addition method. Starting with adding a two-digit number to a three-digit number, they will then extend to adding two three-digit numbers using this method. The main activity allows them to practise this method, and there is an alternative differentiated investigation for those who feel up to the challenge!
