We’ve created a set of printable prime numbers to 100 worksheets designed to make exploring prime numbers a breeze for your students.

In the first worksheet, we’ve kept it simple. It’s a basic 100 square that allows children to dive into the world of prime numbers. Students need to identify and circle the primes, making the learning experience hands-on and interactive.

For a splash of colour and visual aid, the second worksheet has the prime numbers highlighted. This will help students quickly identify and remember the prime numbers.

If you’re aiming for a more focused approach, the third worksheet exclusively features the prime numbers, leaving the remaining squares empty. This concentrated exercise allows students to hone in on the prime numbers without any distractions.

Lastly, we understand the importance of being eco-friendly, so the fourth worksheet has the non-prime numbers shaded in a light grey. This makes the sheet more printer-friendly than our second version.

Ideas for using these worksheets

Begin with the first worksheet where the 100 squares are presented without any highlighting. Ask students to work individually or in pairs to identify and circle the prime numbers. Encourage discussions among students to explain their thought processes and reasoning.

Consider creating a ‘Prime Number Wall’ in your classroom. Display the completed worksheets along with additional prime numbers that students discover independently. This visually reinforces the concept and serves as a handy reference.

Turn prime number identification into a fun challenge. Time students as they complete these worksheets and encourage friendly competition. Consider awarding small prizes for those who successfully identify the most prime numbers accurately.
