Subtract a 2-Digit Number from a 3-Digit Number Lesson

This Year 3 Subtract a 2-Digit Number from a 3-Digit Number lesson covers the prior learning of subtracting two 2-digit numbers with an exchange, before moving onto the main skill of subtracting 2-digit and 3-digit numbers with an exchange.

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.
