Video: Sieve of Eratosthenes: a way to find all the prime numbers from 1-100. I will give you a copy of this chart in class. You will keep this all year because let's be honest not many people have the prime numbers memorized and I don't expect you to either!
Optional Link to do the Sieve for prime numbers online. Play and have fun!
