6.NS.6
Standard: 6.NS.6: Identify and explain prime and composite numbers.
Teacher Background Information:
 A prime number is any natural number with exactly 2 factors, 1 and itself. Any numbers with three factors or more is a composite number.
The numbers 0 and 1 are neither prime nor composite.
All even numbers are divisible by two and so all even numbers greater than two are composite numbers.
All numbers that end in five are divisible by five. Therefore all numbers that end with five and are greater than five are composite numbers.
The prime numbers between 2 and 100 are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89 and 97.

Look at the highway signs below. Circle each highway sign whose number is prime.
The four highway signs below lost their numbers. Each highway number is a composite number that is larger than 40 and
less than 50. Fill in the signs with four different composite numbers that are between 40 and 50.

Each player receives a point if he or she rolled a prime number. Shade in each shape that has a prime number.
After playing for a while, Ashley said, “If you add two prime numbers, you always get a composite number.”
Use the space below to see if Ashley’s statement is correct. Then, fill in the blanks to answer the questions at the bottom of the page.
