## Lesson details

### Key learning points

1. A whole can be represented by one object.
2. If some of the object is missing it is not a whole.
3. Wholes can be different sizes.
4. This is a whole ---- because I have all of it.
5. This is not a whole --- because I do not have all of it.

### Common misconception

Children may think that the size of an object affects whether it is a whole or not.

Show whole objects in different sizes and orientations. Emphasise the language 'whole'.

### Keywords

• Whole - All of something. Complete.

• All of it - All of something. Complete.

• Not whole - Not all of something. Incomplete.

• Part - A piece of a whole.

This lesson starts to explore the concept of a whole being one whole object. Later lessons look at a whole representing a set of objects. Use practical examples of a variety of whole objects that can be cut into parts such as pieces of fruit.
