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

Maths

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

Measures: mass and capacity

A gram is a metric measure of mass. A paper clip has a mass of about 1 gram. The abbreviation is g.

Measure the mass of objects using grams

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

A gram is a metric measure of mass. A paper clip has a mass of about 1 gram.  The abbreviation is g.

Kilograms are use to measure the mass objects that are heavy. A pineapple has a mass of about 1 kilogram.  The abbreviation is kg.

Measure mass in whole kilograms and grams

Capacity is a measure of the maximum amount of liquid a container can hold when full. Capacity can be measured in millilitres.

Volume is the amount of space that an object takes up. In this case, the specific amount of liquid in a container.

The millilitre is a metric measure of capacity or volume.  A millilitre is a very small amount of liquid. The abbreviation is ml.

Understanding capacity and volume

Measuring the volume of liquids using millilitres.

The volume is the amount of space that an object takes up. In this case, the specific amount of liquid in a container.

The millilitre is a metric measure of capacity or volume. It is a very small amount of liquid. One teaspoon can hold 5 ml of water.

The litre is a metric measure of capacity or volume. A litre is made up of 1,000 ml.

Measure volume in whole litres and millilitres

An estimate is a given value, number or quantity that is near to the true amount; it is a number close enough to the right answer.

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

Volume is the specific amount of liquid in a container. Volume can be measured in millilitres or litres.

Comparing and estimating mass and volume

A table is data (a collection of numbers, words, measurements and descriptions of things) arranged in rows and columns.

Estimate then measure mass and volume and record in a table

A bar model is a pictorial representation of a problem where bars are used to represent the known and unknown quantities.

The whole is all of something. It is complete.

A part is some but not all of something. It is an amount or section which, when combined with others, makes up the whole.

Solve problems involving mass

Volume is the amount of space that an object takes up. In this case, the specific amount of liquid in a container. It can be measured in ml.
