The booklet will consist of a cover and the work from the following pages. It is not due until the end of Week 10. [Pick the date] [4TH GRADE MATH HOMEWORK] NOTE: On Wednesday, November 13th, we will be celebrating Prime Number Day! *How many prime numbers can you memorize? * There will be a small prize for everyone who memorizes the first 25 prime numbers! *There will be larger prizes for the three people who memorize the most prime numbers! Week 8: Wednesday, Thursday, Friday Study Guide: A prime number is a whole number greater than zero that has exactly two different factors—1 and the number itself. For example, 5 is a prime number because it only has two factors—1 and 5. A composite number is a whole number greater than zero that has MORE than two different factors. For example, 8 is a composite number because its factors are 1, 2, 4, and 8. What is a factor? A factor is a number that you can multiply together to get another number. For example, what can you multiply to get 8? You can multiply 2 and 4. These are factors of 8. Reminder: 1 is neither prime nor composite. It is not prime because it does not have exactly two factors. It is not composite because it does not have MORE than 2 factors. 1 is a very special number. FUN FACT: Eratosthenes was a famous Greek mathematician who was born about 230 B.C. He was the chief librarian at the University of Alexandria in Egypt. This was the largest and the most famous library in the ancient world. He developed an interesting way to locate prime numbers. It is called the Sieve of [Pick the date] [4TH GRADE MATH HOMEWORK] Eratosthenes and it is still the easiest way to find prime numbers that exist below the number 10 million. Week 8: Wednesday 1) On the next page, cross out the number 1 because it has only 1 as a factor. It is neither a prime nor a composite number. 2) Find a green marker or a green colored pencil. Circle the number 2, the first prime number, and then draw slanting green lines through all of the multiples of 2. a) On a lined sheet of paper or your graph paper, describe what pattern you see with the multiples of 2. [Pick the date] [4TH GRADE MATH HOMEWORK] Sieve of Eratosthenes Week 8: Thursday 1) Circle 3, and draw slanting red lines through every third number. b) On your lined sheet of paper or your graph paper, describe what pattern you see with the multiples of 3. [Pick the date] [4TH GRADE MATH HOMEWORK] 2) Circle 5, and draw slanting black lines through every fifth number. c) On your lined sheet of paper or your graph paper, describe what pattern you see with the multiples of 5. Week 8: Friday 1) Circle 7, and draw slanting blue lines through every seventh number. 2) Circle the remaining numbers that are not crossed out. These are the prime numbers between 1 and 100. d) On your lined sheet of paper or your graph paper, write how many prime numbers did you find? e) Describe why we did not have to go through the multiples of 8. f) Describe why we did not have to go through all the multiples of 9 or 10. Week 8: Monday and Tuesday FUN FACT: Two prime numbers that are separated by only ONE NUMBER are called “twin primes.” For example, 3 and 5 are twin primes. There is only one number that separates them—the number 4! [Pick the date] [4TH GRADE MATH HOMEWORK] 1) Below, complete the list of all twin primes less than 100. Also, find the sums and products of each pair of twin primes.

Challenge Question: Can you give a reason why this pattern exists? What do you think? Week 9: Thursday b) On your lined sheet of paper or your graph paper, describe what pattern you see in the “PRODUCTS” of the twin primes. Challenge Question: Can you give a reason why this pattern exists? What do you think? (HINT: Multiply the number that falls between each twin prime by itself. Compare that answer to the product of the twin primes. What do you notice? For example, what number falls between 3 and 5? The number 4. 4 x 4 = 16 3 x5 = 15 What number falls between 5 and 7? The number 6. 6 x 6 = 36 5 x 7 = 35) Week 9: Friday [Pick the date] [4TH GRADE MATH HOMEWORK] Fun Facts: Do you know what an EMIRP is? It is prime spelled backwards! It is a word used to describe numbers that make other prime numbers when the digits are reversed. For example, 17 is prime and 71 is also prime. 17 is the reverse of 71. 1) List all the emirps between 0 and 100 on your lined sheet of paper or your graph paper. 2) Describe what you notice about the digits of all these emirps. Week 9: Monday Fun Facts: Christian Goldbach was a famous Russian mathematician who was very much interested in prime numbers. Goldbach came up with an idea! His idea said, “Every even number greater than 2 is the sum of two primes.” For example: 4=2+2 6=3+3 8=5+3 1) Write every even number between 10 and 30. Next to it, write down two prime numbers that can be added together to make the even number like the example above. Goldbach’s idea still remains a “conjecture.” A conjecture is an idea that no one can prove! People can find many numbers that work, just as you did, but no one has been able to prove without doubt that Goldbach’s idea will be true for every even number! Can you prove it? Week 9: Tuesday Fun Facts: Christian Goldbach made another “conjecture.” This conjecture said, “Every odd number greater than 5 is the sum of THREE prime numbers. For example: 7 = 3+ 2 + 2 9=3+3+3 11 = 5 + 3 + 3 1) Write every odd number between 7 and 31. Next to it, write down three prime numbers that can be added together to make the odd number like the example above. [Pick the date] [4TH GRADE MATH HOMEWORK] Week 10: Wednesday Fun Facts: In 1976, a seventh grade student by the name of Arthur Hamann “conjectured” (that means, made a guess) that every even number is the difference between two primes. For example: 2=5–3 4=7–3 6 = 11– 5 1) Write every even number between 2 and 30. Next to each number, test Arthur’s idea with subtraction! Week 10: Thursday and Friday Fun Facts: A. de Polignac stated a conjecture very similar to Arthur Hamann’s conjecture. He said that every even number is the difference of two primes right next to each other in and INFINITE number of ways. For example, here are four pairs of prime numbers that are each next to each other, or are consecutive in order, that have a difference equaling 6: 29-23 = 6 37-31 = 6 59-53 = 6 1) For each even number between 2 and 10, find at least three pairs of “consecutive” primes, primes that are right next to each other that’s differences equal the even number. 2 = _______ - ________ ________ 4 = _______ - ________ ________ 6 = _______ - ________ ________ 2 = _______ - ________ 2 = _______ - 4 = _______ - ________ 4 = _______ - 6 = _______ - ________ 6 = _______ - [Pick the date] [4TH GRADE MATH HOMEWORK] 8 = _______ - ________ ________ 10 = _______ - ________ ________ 8 = _______ - ________ 8 = _______ - 10 = _______ - ________ 10 = _______ - Week 10: Monday Fun Fact: Every composite number (that means, a number that is not prime) has a group of prime factors that, when multiplied together, will give you the composite number. For example, 12 = 2 x 3 x 2 (Try it! 2 x 3 = 6 and 6 x 2 = 12) 15 = 3 x 5 24 = 2 x 3 x 2 x 2 Because we are finding the factors that are prime, we call this prime factorization. There’s a special way we do this. We call them factor trees! 1) We write our composite number. 2) We think of two factors that will multiply to give us that number 3) We write those factors and connect them with branches. 4) We circle all the prime numbers—the leaves of our tree. 5) If any number isn’t circled, we go back to Step 2 and repeat! [Pick the date] [4TH GRADE MATH HOMEWORK] 1) Choose five composite numbers between 20 and 40. Draw the factor trees and write the prime factorization for each of the composite numbers.
