How will understanding how to find and use prime, composite, and square numbers be useful to you in your adult life?

In this unit, we will:
1. Find all factor pairs for a whole number in the range of 1-100.
2. Determine whether a given whole number in the range 1-100 is prime or composite.
3. Use square root symbols to represent solutions to equations of the form x2=y and where y is a positive rational number.

4. Evaluate square root of small perfect squares.
5. Research and reflect on our class research question above.

With your table group, discuss the following:
1. You are planning your next birthday party at a really fancy hotel. You have invited 100 people to your party and need to figure out how to seat them. You need to have the same number of people at each table. Find as many different options as you can.
After 10 minutes, you may begin posting your findings here, by adding a comment.

2. UH OH! One person calls at the last minute and says they are bringing a friend You NEED to have tables with equal numbers of people. What can you do?
After 10 minutes, you may post your findings.
We will discuss as a group next.

Watch this video. After you watch, try finding all of the factors of at least one of the following: 35, 54, 88. Take a picture of your work and post it in the comments section below. If you need me, let me know. I am here to help!

Prime Vs. Composite
Visit the link below. You can plug in any number you would like, and the program will create an array for that number.
Try the following numbers and record the results:
31, 99, 78, 61, 43, 67, 89, 32, 46
What did you notice about these numbers and their arrays? Which ones were similar? How were they similar. Try a few more numbers of your choice. How do those connect with the first set of numbers? Why do you think this is? Record your findings, understandings and questions in your math notebook.

You may work with a partner. Complete TWO Frayer Models, one for "composite numbers" in the middle and one for "Prime numbers" in the middle. You may use the internet to help you, but you must cite any resources you use.

You may do these two assignments in any order.

A. Think about our party scenario from the beginning of the week. Think about what you have learned about numbers. Do your own research to learn at least one thing new about prime, composite and/or square numbers.
Journal Question: Why do you think understanding prime and composite numbers is important? Think of and describe at least one scenario where understanding this concept would help you.

B. Now that you have watched Khan Academy videos, you are to create a video of your own! Using technology, create a teaching video for EITHER 1. finding factors of a whole number 2. Determining whether a number is prime or composite or 3. Finding the square root of a whole number. You may be creative, but your video must include everything listed in the rubric.
