List the numbers from 2 to 100. Rows of 10 work well. Cross out all the multiples of 2 that are greater than 2. This will be the rest of the even numbers. Go to the next number that isn't crossed out (3) and cross out all of its greater multiples. Proceed in this fashion. Next up will be 5. You can stop when you get to fifty. The numbers that aren't crossed out are prime.
