## Lesson details

### Key learning points

1. The whole has been divided into __ equal parts.
2. Each equal part is one-__ of the whole.
3. Fractions can be represented as part of a shape or a set.

### Common misconception

Children will often think that the total number within a set is always the denominator as shown in the plates and cupcakes example on the slides.

Put a set of 12 counters (or any countable objects) onto a mini-whiteboard. Children should practise dividing the set into equal groups, drawing rings around them. Repeat, 'The set has been divided into _ equal groups so the denominator is _'.

### Keywords

• Part - The whole is all of a group or number.

• Whole - A part is a section of the whole.

• Equal - Have the same quantity or value.

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

• Set - A collection of items.
