2-Digit and 3-Digit Numbers Lesson

This Year 3 2-Digit and 3-Digit Numbers lesson covers the prior learning of adding and subtracting two 2-digit numbers, before moving onto the main skill of adding and subtracting numbers with 2 and 3 digits.

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