# Use equivalence and compensation strategies to solve addition problems in a range of contexts

I can use equivalence and compensation strategies to solve addition problems in a range of contexts.

## 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.

### Common misconception

The idea of an extra cost being an addition and a saving being a subtraction can seem counter-intuitive to some children.

Talk through a more basic version using a pound for a budget and sweets at a tuck shop.

### 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.

Adjust - When you adjust you make a change to a number.

Redistribution - Redistribution is where some of one part is moved to another part. It is sometimes known as the same sum rule.
