1Prime and Composite Numbers GLE Identify prime and composite numbers.
2Main Goal for Today:Standard Addressed: GLE Identify prime and composite numbers. But…. What are Prime and Composite Numbers?
3Identify Prime and Composite Numbers Prime Numbers- A whole number greater than 1 that has exactly two factors, 1 and itself.Composite Numbers- A whole number greater than 1 that has more than two factors.these Numbers Factors, 2, 3, 2, 4, 5, 2, 3, 6
5Bring the number to life! Items in use: Connecting cubes and white boardsShow me the ways one could arrange the connecting cubes (arrays) for the number 4 ? Then, write all the possible factors for this number on the whiteboards. Classify prime or composite. Why?numbers 1-10
6Hundreds ChartWe are Greek Mathematicians and we are on the hunt for prime numbers!Instructions:put a triangle around the number that is neither prime nor composite,circle the Prime Numbersmark out the Composite Numbers*There are 25 prime number in total between
7Where do you belong? Card Sort Composite vs. Prime Why do you belong there?Hand Transition Activity
8Fruit Shoot Virtual Manipulative Math Games: Prime and Composite Numbers- Fruit Shoot
9Share your thinking while you work! Tic Tac Toe Game …Lets take a lookPartners of 2 (neighbor)Two sided (7-8 minutes a side)Foam squares and diceMay use 100’s chart as guideReview Instructions before start!
10Answer and you shall see prime and composite number are easy! How are composite numbers and prime numbers different?Give an example of an odd number that is composite?(whiteboards)What is the only even prime number? (whiteboards)Roger has 47 cars. Can he group them more than two ways?Why is 1 neither prime nor composite?What’s another way in math that we could use prime and composite numbers other that just identifying and classifying them.
11Think- Pair- ShareKyle has 17 toy trucks. How many ways can the trucks be placed in equal groups?5 ways2 ways3 waysMarla says that every number in the nineties is composite. Jackie says that one number in the nineties is prime. Who is correct? Explain.
