# Year 5 Adding and Subtracting Wholes and Decimals

This Year 5 Adding and Subtracting Wholes and Decimals lesson covers the prior learning of finding complements to 1 and adding and subtracting decimals with different decimal places, before moving onto the main skill of adding and subtracting wholes and decimals.

The lesson starts with a prior learning worksheet to check pupils’ understanding. The interactive lesson slides recap the prior learning before moving on to the main skill. Children can then practise further by completing the activities and can extend their learning by completing an engaging extension task.
