## Lesson details

### Key learning points

- Word problems can be represented in a bar model by identifying the parts and the whole.
- To find the whole, we need to add the parts together.
- To find a part, we need to subtract the part we know from the whole.
- If the units are different, they need to be converted to the same unit.

### Common misconception

Converting between units; interpreting a word problem; confusing parts and wholes.

When representing as a bar model, visualise the problem to help determine what the parts are and what the whole is.

### Keywords

Bar model - A pictorial representation of a problem where bars are used to represent the known and unknown quantities.

Part - Some but not all of something. It is an amount or section which, when combined with others, makes up the whole.

Whole - All of something. It is complete.
