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.
