Year 5 Adding Decimals - Crossing the Whole

This Year 5 Adding Decimals - Crossing the Whole lesson covers the prior learning of adding decimals within 1 and complements to 1, before moving onto the main skill of adding decimals that cross the whole.

The lesson starts with a prior learning worksheet to check pupils’ understanding. If they need more practice, you can choose other resources for those steps here and here. The interactive lesson slides recap the prior learning before moving on to the main skill.
