Study Guides
This pupil-friendly study guide includes a unit summary, clear notes, common mistakes, and quick questions with answers.
Unit Summary
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.
Lesson Summary
You will learn to measure volume in whole litres and millilitres.
Key Notes
- Scales are marked in different ways and counting in 10s, 20s, 50s and 25s helps to read scales.
- The volume of larger amounts of liquids can be measured in whole litres and millilitres.
- There are 1,000 ml in 1 L.
- We can use our knowledge of 1 L and 1,000 ml to determine the volume of liquids.
Vocabulary To Learn
- 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.
Common Mistakes To Avoid
- Children further learn about the composition of 1,000 in Y4, so may make mistakes in reading scales.
3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.
Scales are marked in different ways and counting in 10s, 20s, 50s and 25s helps to read scales. The volume of larger amounts of liquids can be measured in whole litres and millilitres.
2. Use this key word in a maths sentence and explain it clearly. 'Volume'
The volume is the amount of space that an object takes up. In this case, the specific amount of liquid in a container. Use this word when showing your method, then check your final answer is reasonable.
3. Spot and fix this common maths mistake.
Mistake: Children further learn about the composition of 1,000 in Y4, so may make mistakes in reading scales. Correction: 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.
