Understand that parts can be represented in any order
Lesson details
Learning outcome
I know that parts can be combined in any order and can represent this.
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.
Teacher tip
Plan to explore contexts where parts can be reversed and don't initially appear to match visuals so that this can be discussed and corrected. Always ensure precise language is used when describing what each number in the expression represents.
