Finding the Difference Lesson

This Year 1 Finding the Difference lesson covers the prior learning of counting objects and identifying which group has the most and least, before moving onto the main skill of solving subtractions by finding the difference between two numbers.

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.
