# Prime Numbers

To define what makes a prime number students begin the lesson by calculating factors of several integers.  Prime numbers are then defined and listed.  To aid their recollection of the first 12 primes students are challenged to apply them within calculations.  As learning progresses students use the Sieve of Eratosthenes to calculate all the primes up to 100.
