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 explain that items can be compared using length and height, mass and volume/capacity. They will compare sets of objects using equality/inequality symbols. Pupils will also explore part-part-whole relationships with representations.
Lesson Summary
You will learn to compare items according to their volume and capacity.
Key Notes
- Know the language used when comparing volume and capacity, more than, less than, equal to, the same.
- Know less is used when the noun cannot be counted and fewer is used to descibe countable nouns.
Vocabulary To Learn
- more than: has a greater amount / more items.
- less than: has a lesser amount / fewer items.
- the same: exactly the same amount or value.
- capacity: the amount that something can hold.
Common Mistakes To Avoid
- Children may assume that taller objects have more capacity.
3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.
Know the language used when comparing volume and capacity, more than, less than, equal to, the same. Know less is used when the noun cannot be counted and fewer is used to descibe countable nouns.
2. Use this key word in a maths sentence and explain it clearly. 'more than'
has a greater amount / more items. 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 assume that taller objects have more capacity. Correction: Compare real containers and demonstrate with water. Taller containers may be thinner and have less capacity.
