Activity Introduction

In this lesson, students practise converting numbers into percentages, and adding percentages together.

Students learn about their recommended daily intake of sugar, and practise adding different foods together to reach 100% of their daily intake. As the lesson proceeds, the questions increase in difficulty, culminating in a small research project where students find their own products, convert the sugar amount into a percentage, and then carry out basic percentage addition, thereby getting a sense of proportion around the recommended daily sugar intake. 


Learning Intentions

  • Students know how to find percentages

  • Students understand the link between average quantity per serving and average quantity per 100g.
