3-Digit Numbers and Tens Lesson

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

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.
