Identify Primes

Worksheet Description

This worksheet provides a list of numbers and asks students to determine whether each one is a prime number or a composite number. Each number is presented in a box with two options next to it: “Prime” and “Composite.” Students are expected to check or circle the correct option based on the nature of the number. The numbers listed are mixed to include both prime and composite numbers, and they range from smaller to larger values within the typical scope of elementary to middle school math curricula.

The worksheet is designed to teach students the difference between prime and composite numbers through direct application. By evaluating each number, students practice the skill of recognizing prime numbers, which have only two divisors, and composite numbers, which have more than two. This activity aims to reinforce the students’ understanding of number theory and divisibility rules. Moreover, it encourages the development of critical thinking as students must assess each number independently to determine its classification.
