### Key learning points

- Visualising a word problem helps us see the mathematics.
- Word problems can be represented as a bar model by identifying the parts and the whole.
- The bar model helps us to understand the structure of the maths and to form a calculation to help solve the problem.
- Number facts can be used when solving problems involving mass.

### Common misconception

Children may misidentify the parts or wholes in a problem.

Children should be encouraged to visualise the problem (eg. act it out or draw it) to help them identify the parts and whole.

### Keywords
