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 estimate and then measure mass and volume and record in a table.
Key Notes
- Estimating is important. If we estimate accurately, it helps us check if our actual measurements are accurate.
- We can record our measurements in a table, which is a presentation of information so data can be interpreted easily.
Vocabulary To Learn
- Estimate: An estimate is a given value, number or quantity that is near to the true amount; it is a number close enough to the right answer.
- Table: A table is data (a collection of numbers, words, measurements and descriptions of things) arranged in rows and columns.
Common Mistakes To Avoid
- Children may estimate incorrectly or confuse where to record their measurements in the table.
3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.

2. Use this key word in a maths sentence and explain it clearly. 'Estimate'
An estimate is a given value, number or quantity that is near to the true amount; it is a number close enough to the right answer. 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 estimate incorrectly or confuse where to record their measurements in the table. Correction: When estimating, hold an item of known mass in one hand and the unknown in the other - compare them. Take care when reading table headings.
