## Lesson details

### Key learning points

1. Scales are marked in different ways and counting in 10s, 20s, 50s and 25s helps to read scales.
2. The volume of larger amounts of liquids can be measured in whole litres and millilitres.
3. There are 1,000 ml in 1 L.
4. We can use our knowledge of 1 L and 1,000 ml to determine the volume of liquids.

### Common misconception

Children further learn about the composition of 1,000 in Y4, so may make mistakes in reading scales.

Rehearse 1,000 is composed of two equal parts of 500 ml, four equal parts of 250 ml, five equal parts of 200 ml, 10 equal parts of 100 ml.

### Keywords

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

• Millilitre - 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.

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

Make the lesson as practical as possible. Physically show the children the difference between 1 ml and 1 L so they grasp the difference in amount. Support children to become confident with measuring larger amounts of liquids over 1 L.
