Integers are all around us in everyday life, even though we might not always realize it! Here’s how to explain integers and connect them to real-world situations:
**1. What Are Integers?
- Basic Definition: Integers are whole numbers that can be positive, negative, or zero. They include numbers like −3, −2, −1, 0, 1, 2, and 3.
- Understanding Positive and Negative: Positive integers are numbers greater than zero (like 111, 222, 333), while negative integers are less than zero (like −1, −2, −3).
**2. Everyday Examples of Integers
- Temperature:
- Positive: On a warm day, you might say it’s 25°C. That’s a positive integer.
- Negative: On a cold winter day, you might say it’s −5°. That’s a negative integer.
- Bank Accounts:
- Positive Balance: If you have $50 in your account, that’s like a positive integer: +50.
- Negative Balance: If you owe the bank $20, that’s like a negative integer: −20.
- Elevation:
- Above Sea Level: A mountain peak 500 meters above sea level is represented by +500 meters.
- Below Sea Level: The Dead Sea is about 430 meters below sea level, represented by −430 meters.
- Game Scores:
- Winning: If your team scores 3 points, that’s +3.
- Losing: If you lose 2 points due to a penalty, that’s −2.
