## Lesson details

### Key learning points

1. The volume of liquid in a container can be measured in millilitres.
2. When comparing volume, if the containers are the same, we can compare the level of liquid in the container.
3. When comparing volume, if the containers are different, we need to take read the scale on the measuring container.
4. Counting in 10s, 20s, 25s and 50s helps to read scales.

### Common misconception

Children may read the scale incorrectly - confusion between equal parts and marks on the scale.

The scale is a number line. Remember to look at the number of equal parts between the marked numbers not the marks themselves.

### Keywords

• Volume - 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. A millilitre is a very small amount of liquid. The abbreviation is ml.

This should be a practical lesson where possible. Children need to have physical experience of using different containers and reading different scales when measuring volume. No more than 1,000 ml for this lesson.
