Step 2

sharing opinions

This activity shows students how different kinds of food are grouped according to the benefit they

give us. This is important as it allows us to talk about the value of particular food to our health.

Everybody has to eat, but do you eat a healthy diet? Do you know that the food you eat

helps you grow in different ways?
