Lesson details
Key learning points
- If the whole is the same, then two parts can be compared directly.
- If the whole increases whilst the part stays the same, then the part becomes a smaller part of the whole.
- If the whole decreases whilst the part stays the same, then the part becomes a bigger part of the whole.
- Part and whole need consideration when judging whether a relatively large or small part of the whole is identified.
Keywords
Whole - The whole is all the parts or everything, the total amount.
Part - A part is some, but not all, of the whole.
Common misconception
Children may struggle to understand that parts change size when the whole changes. A relative size of a part that stays the same whilst the whole changes is a tricky concept.
What do you notice? What is the same? What is different?
