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 measure length in any direction to give height, length and distance.
Key Notes
- If we all choose our own way to measure, we will end up with different measurements of the same thing.
- When you use the same unit of measure, you will get the same result.
- Standard units of measure are useful because they are always the same size and do not change.
- Centimetres are an example of a standard unit.
Vocabulary To Learn
- Unit of measure: Something used as a standard of measurement. It is '1' of the measurement.
- Standard unit: Uniform units of measure that are agreed throughout a community.
Common Mistakes To Avoid
- Children may think that the same type of object, for example a pencil, can be used as a unit of measure, even when they are different lengths.
3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.

3. Spot and fix this common maths mistake.
Mistake: Children may think that the same type of object, for example a pencil, can be used as a unit of measure, even when they are different lengths. Correction: Read the story of Pedro's birthday quest again and discuss why the friends using their own footsteps for measuring led to them getting different results.
