Odd numbers are whole numbers that cannot be divided by 2 without leaving a remainder. Examples include 1, 3, 5, 7, and so on. Understanding odd numbers is fundamental for grasping number theory and arithmetic operations. They play a crucial role in various mathematical concepts, such as divisibility rules and algebraic equations. In real-world applications, odd numbers are used in scheduling, computer algorithms, and statistical analysis. Understanding odd numbers helps students grasp the concept of parity and develop their number sense, which is essential for higher-level mathematics.

**Teacher script**: "Odd numbers are like socks that don't have a pair. If you have 3 socks, one sock is left without a pair. That's an odd number."
