Lesson details
Key learning points
- A whole can be represented by one object.
- If some of the object is missing it is not a whole.
- Wholes can be different sizes.
- This is a whole ---- because I have all of it.
- This is not a whole --- because I do not have all of it.
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.
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'.
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.
