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 use the equality and inequality symbols to compare the relative size of two numbers.
Key Notes
- Use the symbols < > and = to compare pictorial representations.
- Use the symbols < > and = to compare numerical expressions.
- Compare 2 sets where the objects are not arranged linearly.
- Use a number line to help with sense of number.
- Moving along the number line corresponds to an increase in the value of the numbers - movement is magnitude.
Vocabulary To Learn
- number line: a line with numbers placed in their correct position.
- more than / greater than: has a greater amount / more items.
- fewer than / less than: has a lesser amount / fewer items.
- equal to / the same: exactly the same amount or value.
Common Mistakes To Avoid
- Children may confuse the symbols < and >
3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.
Use the symbols < > and = to compare pictorial representations. Use the symbols < > and = to compare numerical expressions.
2. Use this key word in a maths sentence and explain it clearly. 'number line'
a line with numbers placed in their correct position. 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 confuse the symbols < and >. Correction: Use lots of practical examples with cubes or objects inside the symbols so children can see the larger end contains the greater amount.
