Students learn how to calculate a percentage of an amount using either 10% or working with equivalent fractions. As learning progresses students move on to calculate decimal percentages such as 33.33% or 12.5%.

The start of the lesson recaps converting between percentages and simplified fractions. The plenary challenges students to interpret a pie chart where the proportions are given as a percentage.

**Differentiated Learning Objectives**

- All students should be able to calculate a percentage of an amount using 10%.
- Most students should be able to calculate a percentage of an amount using equivalent fractions.
- Some students should be able to calculate a percentage of an amount without a calculator.
