Step by step directions for finding prime numbers between 1 and 100

Prime & Composite Numbers •A prime number has only two factors, 1 and itself. •A composite number has more than two factors. •“1” is a special case. It is neither prime nor composite since it has only one factor, which is 1. •“2” is the only even prime number. All other even numbers are divisible by 2, so all other even numbers are composite. Let’s find the prime numbers from 1 – 100… •Put a box around “1” because it is neither prime nor composite •Circle “2.” It is the first prime number. Now cross out all multiples of 2. •Circle “3.” It the next prime number. Cross out all multiples of 3. •Circle “5.” It is the next prime number. Cross out all multiples of 5. •Circle “7.” It is the next prime number. Cross out all multiples of 7. •Highlight all numbers circled or not crossed out – these are the PRIME numbers from 1 – 100. There should be twenty-five prime numbers.
