Prime or Composite?

You’re about to become a number detective! When you know how to tell the difference between prime and composite numbers, you unlock a key part of math that helps with factors, multiplication, and even fractions. This playsheet helps you build that skill with fun and simple challenges.
 

You’ll practice testing numbers to see if they can only be divided by 1 and themselves (prime!) or if they have more than two factors (composite!). Each question helps you think logically and recognize important patterns in numbers.
 

You’ll also sharpen your problem-solving skills as you work through lists, sort numbers, and apply what you’ve learned. With each activity, you’re training your brain to ask the right questions and make quick, accurate decisions.
