Lesson details

Common misconception

When finding a price has reduced by 25%, pupils may give the answer as 25% of the number, rather than seeing it as 75% of the whole.

Emphasise that '25% off' means that the price has been reduced by 25%. The whole, subtract 25%, is equal to 75% of the whole. Bar models are useful for showing this.

In this lesson, pupils solve a range of problems using percentages, including problems with an unknown part or an unknown whole. Encourage pupils to use tables to help them organise their thinking and, where needed, represent problems using bar models.
