## Lesson details

### Key learning points

- A change in length can be described using multiplication.
- The stem sentence, 'The ___ is ___ times the length of the ___' can be used to compare lengths.
- Comparison and change problems can be represented visually to support solving them.

### Common misconception

Children may say, 'Tens times taller', which is imprecise.

We say, 'Ten times the original height' because this is more precise and can be used when the scale factor is fractional.

### Keywords

Comparison - When a comparison is made, we are determining how different two objects are. In this case, how many times longer, taller or deeper an object is than another.

Change - A comparison can also be made between an object at the start of, and then after, a change. Examples of change include a change in height of a flower due to growth.
