Finding a Part Lesson

This Year 1 Finding a Part lesson covers the prior learning of adding together two parts to find a total, before moving onto the main skill of finding a part by counting on.

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. 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.
