Estimate in metres and describe a metre in different ways
Lesson details
Learning outcome
I can estimate lengths and heights in metres and describe a metre in different ways.
Key learning points
- The length or height of an object can be estimated using the standardised unit of metres.
- One hundred, 1 cm lengths are the same as 1 m.
- Ten, 10 cm lengths are the same as 100 cm, which is the same as 1 m.
Keywords
Estimate - An estimate is a given value, number or quantity that is near to the true amount.
Metre - A metre is a standardised unit of measurement. We can abbreviate metre to m.
Centimetre - A centimetre is a standardised unit of measurement. We can abbreviate centimetre to cm.
Common misconception
100 cm is bigger than 1 m.
1 m is equal in length or height to 100 cm. 100 cm make up 1 m. They are the same length or height.
Teacher tip
Children need a concrete example of a metre and how long and tall 1 m is. Where possible, the suggested activities should be carried out practically.
