About Rulers
There are many different kinds of rulers but they all do the same job. There are metre rulers which can measure as long as 1 meter and as small as 1 millimeter. There are 'foot' rulers which can measure as long as 30 centimetres and as short as 1 millimetre. Some rulers are made of wood and some rulers are made of plastic.
Examples
- A scientist measured the length of a table.
- A scientist measured the height of their friends.
- A scientist wants to measure the distance from the office to the laboratory.
Used in a Sentence

- The height of the scientist's friends was found using a ruler.

Note for Teachers
- You may wish to avoid referring to a 30cm ruler as a foot ruler. 30cm is not exactly 1 foot, since 1 foot is 12 inches and there are 2.54 cm in 1 inch. This makes a foot 30.48cm.
