Step 1: Check our Understanding

Remember: A prime number is a number that has only two factors: 1 and itself. A composite number has more than two factors.

Examples:
– Prime: 2, 3, 5, 7, 11 (only divisible by 1 and itself)
– Composite: 4, 6, 8, 9, 10 (divisible by more than just 1 and itself)


Let’s circle the prime numbers below:

2, 4, 5, 6, 7, 8, 9, 11, 12, 13, 15, 17, 18, 19, 20,
