Lesson Details
Key learning points
- Parts of the same sized whole can be compared.
- A bigger or smaller part of the whole can be shown.
- Different parts of the same sized whole can be directly compared based on their size.
Common misconception
The part changes size when the whole changes.
Use the bottles example in the slides to overcome this. Have a range of different sized containers for water and demonstrate the concept practically.
Keywords
