A metric measure of distance used for small lengths.

The basic unit of length (or distance) in the metric system.

A metric measure of distance, equal to 1,000 metres.

A gram (g) is a measure of mass. 1,000 grams are equivalent to one kilogram (kg).

A millilitre (ml) is a measure of capacity. 1,000 millilitres are equivalent to one litre (l)

Use knowledge of 1,000 to explain common measure conversions

Maths

 In this unit pupils will use knowledge of 1000 to explain common measure conversions and solve problems. In the future unit pupils will use their knowledge of decimal place value to convert between and compare metres and centimetres and explain that different lengths can be composed additively and multiplicatively.

In the prior unit pupils used weighing scales up to 1kg and measuring tools for volume and capacity up to 1 litre. They measured mass from 0 to above 1kg using whole kg and grams and measure volume from 0 to above 1 litre using whole litres and ml.  In this unit pupils will use knowledge of 1000 to explain common measure conversions and solve problems.
