44. Prime/Composite Numbers Through trial and error students determine if a number is prime or composite. If they try every possible factor for 17, the student will see that 17 is prime.

45. Prime/Composite Numbers So 17 is a Prime Number.

46. Prime/Composite Numbers MathLine answers “WHY?” “Why is 17 Prime?” On MathLine we can see why, that’s what makes it powerful.
