Today we start Unit 5, focusing on the unique (and sometimes mysterious-:) numbers known as prime and composite numbers. We learned that prime numbers have only two factors: the number itself and one. Another way of describing a prime number is that it can be divide equally only by itself and one. A composite number (“composed” or made up of prime numbers) has more than two factors. We investigated the patterns of primes up to 100 and previewed how prime numbers shape math and other fields.
