What Does Each Term Mean?

Prime Numbers

A prime number is a number greater than 1 that has only two factors: 1 and itself. In other words, it cannot be divided evenly by any other number.

• Part of speech: Noun
• Easy examples:
  1. 2 (only divisible by 1 and 2)
  2. 3 (only divisible by 1 and 3)
  3. 17 (only divisible by 1 and 17)

Mini Story: Imagine a prime number is like a single superhero. It works alone and cannot team up evenly with any other numbers except 1 and itself.

Composite Numbers

A composite number is a number greater than 1 that has more than two factors. It can be divided evenly by numbers other than 1 and itself.

• Part of speech: Noun
• Easy examples:
  1. 4 (divisible by 1, 2, 4)
  2. 6 (divisible by 1, 2, 3, 6)
  3. 12 (divisible by 1, 2, 3, 4, 6, 12)

Mini Story: Think of composite numbers as a team. They can split into smaller groups and still work perfectly.

Common Mistakes and How to Avoid Them

1. Mistake: Saying 1 is prime
   • Correction: 1 is neither prime nor composite. It only has one factor.
2. Mistake: Thinking even numbers are always composite
   • Correction: 2 is even but also prime!
3. Mistake: Confusing small numbers like 17 or 19
   • Correction: Check factors carefully. Only 1 and itself → prime.

Tip: Write out factors for tricky numbers to avoid mistakes.

When to Use “Prime”

Prime numbers are used in:

• Math problems in school
• Coding and computer security (encryption)
• Finding patterns in numbers

Examples:

1. 17 is prime.
2. The number 13 is prime.
3. 2 and 3 are the smallest prime numbers.
4. Prime numbers cannot be split evenly except by 1 and themselves.

Visual Hack: Imagine prime numbers wearing a crown. They stand alone!

When to Use “Composite”

Composite numbers appear in:

• Dividing things evenly (like candy or coins)
• Multiplication practice
• Problem-solving involving factors

Examples:

1. 12 is composite because it can be split into 3×4.
2. 20 is composite (divisible by 2, 4, 5, 10).
3. 9 is composite (divisible by 3×3).
4. Composite numbers can form smaller groups.

Memory Trick: Think of composite numbers as a team of friends that can split into smaller groups.
