Compare Lengths Lesson

This Year 3 Compare Lengths lesson covers the prior learning of comparing and ordering lengths where either the metric unit is the same, or the number, before moving onto the main skill of comparing and ordering lengths that may have different metric units of mm, cm or m.

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