Count One Less Lesson

This Year 1 Count One Less lesson covers the prior learning of counting one less using practical equipment, before moving onto the main skill of recalling one less than a given number within 10.

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.
