Investigate everyday situations that use integers. Locate and represent these numbers on a number line (ACMNA124)
LO: To identify real-life situations that use integers and to locate and represent these numbers on a number line.
- What an integer is
- When integers are used in real life
- That integers are used every day to represent certain situations..
- I can identify what an integer is
- I can put integers on a number line.
- What are integers?
- When do we work with integers in the real world?
- Are there only positive numbers in the world?
- Does adding two numbers always give me a positive answer?
Integers are whole numbers which can be positive or negative.

Examples of integers
Not examples of integers
- 2.5, 1/4, 37.86, $204.35, 32.5%
Integers on a number line
- Negative numbers are usually to the left of 0.
- Positive numbers are usually to the right of 0.
- As you move further away from 0, the number gets larger (moving right) or the number gets smaller (moving left).
