Add and Subtract 10s Lesson

This Year 2 Add and Subtract 10s lesson covers the prior learning of counting on and back to add and subtract a one-digit number, before moving onto the main skill of adding and subtracting 10s numbers to and from any 2-digit number.

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.
