A prime number chart is a useful tool to help kids memorize all the prime numbers between 1 and 100. A prime number is a number that is only divisible by one and itself, and has no other factors. I’ve made two free prime number charts parents, teachers, and students to use. The first chart is black and white, and the second has been colored. They have been saved as letter-sized pdfs for easy printing. Click on the worksheet images below to open the pdf in your browser, and download the file to your computer.
These worksheets are free for personal and educational use only. Commercial use is prohibited.
