Sieve of Eratosthenes is a Greek Math’s classic. This is an engaging way for students to find Prime Numbers using multiples of numbers. This version I made goes up to 100 and takes about 10 -20 minutes depending on your class. The** answers** are on the second sheet for quick reference. If you are looking to inject excitement and movement into your maths class. Optionally, the Sieve worksheet forms the pre-learning for the maths game Decrypto Racer, on my resources tab. Decrypto is a high speed composite number game where students race to break the numbers down into prime factors. Running for 20 - 40 minute one of my students called it ‘Exciting and Stressful!’.

Idea for grades 7 - 9. All you will need to do is print out the worksheets and answers. Then** build the decks of cards** for the number of games you need. This can take a little time. But you have the resource to use again and again. Worksheet in class takes students about 15 - 30 min. Scale Stacker Game in class takes students about 30 - 45 min.
