Capacity

Capacity

Capacity is an important mathematical concept for children to learn.   In Mathematics, the term capacity is used when measuring how much fluid fits inside a container. It is measured in millilitres and litres, or, in imperial, pints and gallons.   In Year 3 children start to learn about the relationship between millilitres and litres.They are taught that there are 1000 ml in one litre. They are also given activities to do, involving measuring amounts of water in a measuring jug in millilitres. They might be given a picture of a measuring jug where the water is shown to be halfway between the 100ml and 200ml marks and asked to say how much water is in the jug. Children in Year 3 are also given capacity problems to solve  involving comparing, adding and subtracting measurements of liquid.
