Lesson details
Key learning points
- When parts of a whole are added together, each part is called an addend.
- You can combine the parts in any order because they still make the same whole.
- You can write the addends in any order because, when combined, they still make the same whole.
Keywords
Partition - To split a whole up into parts (pieces or sections of the whole).
Combine - To put parts together to make a whole.
Common misconception
Children may believe that addends must be represented in a certain order.
Ensure parts are seen alongside objects and pictures presented in different ways so the visual always matches the given expression.
