**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.
**

**Know:**

- What an integer is
- When integers are used in real life

**Understand:**

- That integers are used every day to represent certain situations..

**Do:**

- I can identify what an integer is
- I can put integers on a number line.

**Essential Questions:**

- 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?

**Notes**

Integers are whole numbers which can be positive or negative.

Integers which are greater than > 0 are positive.

Integers which are less than < 0 are negative.

**Examples of integers**

- 2, +4, -120, -13, 15

**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).
