Estimate Answers Lesson

This Year 3 Estimate Answers lesson covers the prior learning of adding and subtracting multiples of tens and hundreds, before moving onto the main skill of estimating answers using near 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. Children can then practise further by completing the activities and can extend their learning by completing an engaging extension task.
