## Lesson details

### Key learning points

1. Equal parts may not look the same.
2. The whole has been divided into __ equal parts.
3. One equal part has been filled so each equal part is __ of the whole.

### Common misconception

Children might think that the parts of the whole they create in Task B have to be able to fit together to make the same shape as the whole.

Reinforce the concept that the whole is about quantity and not necessarily about shape. Plasticine is a good way to demonstrate this.

### Keywords

• Whole - The whole is all the parts or everything, the total amount.

• Part - A part is some of the whole.

• Equal - Have the same quantity or value.

• Unequal - Do not have the same quantity or value.

Make sure you've plenty of cubes, containers and plasticine to reinforce the concepts practically. This lesson is about experiencing the learning as much as visualising.
