Efficient Subtraction Lesson

This Year 4 Efficient Subtraction lesson covers the prior learning of looking at different methods of subtraction including counting on using a number line, before moving onto the main skill of identifying the most efficient method of subtraction.

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.
