What do we use to measure the height, length or width of something?
We use lots of different objects to measure with.
Each object usually has one or two units of measurement on it.

Here’s a hint ---- centimetres

What do we use to measure things?
Our length, height and width measuring toolbox could include these units of measurement
Metres
Millimetres
Kilometres

How do we choose which one to use?
That’s a difficult question to answer
Usually you choose units that are going to make sense for the problem you are working out.
We tend to change to a bigger unit when it is going to take us a long time to measure something in the smaller unit
It takes practice and careful thinking to choose a measurement unit
