Lesson details
Key learning points
- When measuring, it is more efficient to start at zero.
- The length of the object is the difference between the numbers on the ruler at the start and the end of the object.
- Measures can be given in metres or centimetres.
- Estimating helps us to decide if it is better to measure in centimetres or metres.
Keywords
Metre (m) - A metre is a standardised unit of measurement. We can abbreviate metre to m.

Common misconception
The length or height of an object is the numerical value at the end of the ruler (if not at zero).
If an object is not measured from zero, its length is the difference between the numerical value at the start and end of the object.
