Add Lengths Lesson

This Year 3 Add Lengths lesson covers the prior learning of solving one and two step problems involving lengths of the same metric unit, before moving onto the main skill of adding lengths that may require conversions.

The lesson starts with a prior learning worksheet to check pupils’ understanding. If they need more practice, you can choose other resources for the step here. 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.
