Lesson details
Key learning points
- The part-whole structure can be used to represent additive problems in a range of contexts.
- A bar model structure can be used to represent additive problems in a range of contexts.
- The same sum rule can be used to solve additive problems in a range of contexts.
Keywords
Budget - A budget is the total amount of money that you have to spend on something. It is often split into parts and money can be redistributed between these parts.
Unknown - An unknown is a quantity that has a set value but it is represented by a symbol or letter.
