Key Stage 1
Meaning
A Ruler is a piece of equipment we can use to measure how long something is.
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 metre and as small as 1 millimetre.
- 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
- A ruler was used to measure the length of a table.
- The height of the scientist's friends was found using a ruler.
- The scientist's ruler was too short to measure the distance form the office to the laboratory
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.
Key Stage 2
Meaning
A ruler is a piece of equipment used to measure the distance between two points.
About Rulers
- Rulers can be used to measure the length, width and height of objects.
- Metre rulers can measure as long as 1 metre and as small as 1 millimetre.
- There are 'foot' rulers 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.
Key Stage 3
Meaning
A ruler is a measuring instrument used to measure the distance between two points.
About Rulers
- Rulers can be used to measure the length, width and height of objects.
- Rulers used in the lab are usually divided into centimetres and millimetres.
- Metre rulers can measure as long as 1 metre and as small as 1 millimetre.
- There are 'foot' rulers 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.
Key Stage 4
Meaning
A ruler is a measuring instrument used to measure the distance between two points.
About Rulers
- Rulers can be used to measure the length, width and height of objects.
- Rulers used in the lab are usually divided into centimetres and millimetres.
- Most rulers have a resolution of 1 millimetre because that is the smallest the human eye can correctly read.
- To use a ruler accurately the reading from each end should be checked before subtracting one from the other to find the distance.
