Mass is a measure of how much matter something contains. It is measured by how much something weighs. Mass can be measured in grams.

A gram is a metric measure of mass (which we feel as weight). A paper clip weighs about 1 gram. The abbreviation is g.

Intervals are the spaces between given numbers. They include all given numbers between the numbers marked at the start and end.

Become familiar with scales with different intervals when measuring in grams

In this unit pupils will become familiar with different weighing scales up to 1kg and with the tools to measure volume and capacity up to 1 litre. They will measure mass from zero above 1kg using whole kg and grams and measure volume from zero above 1 litre using whole litres and ml. In the future unit pupils will use knowledge of 1000 to explain common measure conversions and solve problems.

In the prior unit pupils used and compared standard units to estimate and measure length/height, mass, temperature, capacity to the nearest unit. In this unit pupils will use weighing scales up to 1kg and measuring tools for volume and capacity up to 1 litre. They will measure 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
