Unit Summary
In this unit pupils will interpret numbers greater than and less than zero. They will read and write negative numbers, explain how the value of a number relates to its position from zero, positioning on a number line.
Lesson Summary
You will learn to identify and place negative numbers on a number line.
Key Notes
- Counting backwards can continue past zero and include negative numbers.
- Positioning negative numbers on marked and partially marked number lines.
- Understanding that fractions and decimals can be positive or negative.
Vocabulary To Learn
- Interval: An interval is what is between two values. On a scale, intervals are shown using a small mark or line to show the space between.
Common Mistakes To Avoid
- Fractions and decimals less than one are positioned to the left of zero or are negative in value.
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. 'Interval'
An interval is what is between two values. On a scale, intervals are shown using a small mark or line to show the space between. Use this word when showing your method, then check your final answer is reasonable.
3. Spot and fix this common maths mistake.
Mistake: Fractions and decimals less than one are positioned to the left of zero or are negative in value. Correction: Using a number line 0 to 1, label different fractions and decimals and show pupils that, though small in size, they are greater than zero.
