Tens and Ones (to 50) Lesson

This Year 1 Tens and Ones(to 50) lesson covers the prior learning of tens and ones within 20, before moving onto the main skill of representing tens and ones within 50.

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.
