Prime and Composite Numbers Resources
Prime and composite numbers are foundational concepts in number theory, helping students understand the factors that make up whole numbers. A prime number is greater than 1 and has exactly two factors: 1 and itself, while a composite number has more than two factors. The number 1 is considered neither prime nor composite. Recognizing these numbers supports skills in multiplication, division, and more advanced mathematical reasoning.
Education.com’s Prime and Composite Numbers resources provide engaging ways for learners to explore these concepts. Students begin by identifying prime numbers such as 2, 3, 5, 7, and 11, then distinguish them from composite numbers like 4, 6, 8, and 9. Lessons introduce factors as numbers multiplied together to produce a product, helping learners understand why primes have exactly two factors. Activities include guided worksheets, interactive exercises, and games to reinforce understanding and encourage repeated practice.
Resources are designed for classroom and at-home learning, supporting visual, hands-on, and digital learners alike. By working through these materials, students strengthen number sense, gain confidence in identifying primes and composites, and build a solid foundation for future topics in multiplication, division, and algebraic thinking. Filters by grade, topic, and resource type make it easy for parents and teachers to select the most relevant practice for each student’s needs.

A Guide to Prime and Composite Numbers
Need a refresher on prime and composite numbers? Look no further!
Prime Numbers
Prime numbers are whole numbers that can only be divided by 1 and itself. Prime numbers do not, however, include the number 1, so the smallest prime number is 2. Some examples of prime numbers are 3, 5, 7, 11, and 13.
Composite Numbers
Composite numbers are also whole numbers, but they are different from prime numbers because they can be divided by numbers other than 1 and itself. The number 1 is also not considered a composite number, so 4 is the smallest composite number. Even numbers (excluding 2) are all examples of composite numbers.
Factors
Factors are another mathematical concept used to define prime numbers. Factors are the numbers that are multiplied together to get a final product. For example, in the equation 3 × 2 = 6, 3 and 2 are both factors. Using this definition of factors, we can now say that a prime number is any number that has only two factors that are 1 and the number.
Prime and composite numbers are some of the basic building blocks of math and can be used to help understand multiplication and division concepts. To get more practice using prime and composite numbers, check out our worksheets, games, and exercises!
