- Pencil
- Calculator (optional)
No prior knowledge is required for this lesson.
Activities
- Number System Exploration: Create a number line from -10 to 10 and place various numbers on it. Identify integers, fractions, and decimals.
- Properties Game: Write down different numbers and let's play a game to identify if they are even, odd, prime, or composite.
- Number Puzzles: Solve number puzzles involving factors, multiples, and divisibility rules to enhance your understanding of number properties.
Talking Points
- Introducing Number System: "The number system includes integers, fractions, and decimals. Let's explore how these numbers are related to each other."
- Understanding Even and Odd Numbers: "Even numbers can be divided by 2 without leaving a remainder, while odd numbers cannot. Can you identify which numbers are even or odd?"
- Exploring Prime Numbers: "Prime numbers have exactly two factors - 1 and the number itself. Can you find some examples of prime numbers?"
- Diving into Divisibility Rules: "Divisibility rules help us determine if a number can be divided by another number without leaving a remainder. Let's practice some divisibility rules together."
