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 choose, use and compare appropriate standard units to estimate and measure length/height mass, capacity and temperature to the nearest appropriate unit.
Lesson Summary
You will learn to compare and order measurements of volume and capacity.
Key Notes
- You can compare capacity in the same way as we compare 2-digit numbers.
- When the units are different and the numbers are the same, you can compare measurements by looking at the numbers.
- You can pour liquid from one container into another to compare their capacities.
Vocabulary To Learn
- Volume: The amount of space something takes up.
- Capacity: The amount of liquid something can hold.
Common Mistakes To Avoid
- Children may think that a taller container always has a larger capacity.
3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.
You can compare capacity in the same way as we compare 2-digit numbers. When the units are different and the numbers are the same, you can compare measurements by looking at the numbers.
2. Use this key word in a maths sentence and explain it clearly. 'Volume'
The amount of space something takes up. Use this word when showing your method, then check your final answer is reasonable.
3. Spot and fix this common maths mistake.
Mistake: Children may think that a taller container always has a larger capacity. Correction: Choose tall narrow containers alongside short, wide containers and compare the capacities in different ways, such as recording a measurement for each capacity as well as pouring from one container into another to see which has the greater capacity.
