# Calculating Ratio Lesson

This Year 5 Calculating Ratio lesson covers the prior learning of introducing ratio language and the ratio symbol, before moving onto the main skill of calculating ratio.

The lesson starts with a prior learning worksheet to check pupils’ understanding. 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.
