Is the Number Prime or Composite

Level 5

This math topic focuses on determining whether given numbers are prime or composite. It is part of a broader unit on factoring and finding the greatest common factor. The problems present a number and ask students to classify it as either prime (a number with only two positive divisors: 1 and itself) or composite (a number with more than two positive divisors). Each problem provides two answer choices: prime or composite, thus reinforcing students' understanding and ability to distinguish between prime and composite numbers.
