Year 5 Complements to 1

This Year 5 Complements to 1 lesson covers the prior learning of making a whole, before moving onto the main skill of making complements to one with numbers up to three decimal places.
The lesson starts with a prior learning worksheet to check pupils’ understanding. If they need more practice, you can choose other resources for that step.
