# The Number System

Introduction

Numbers are all around us.  We see and use them in our daily lives whether we realize we are or not.  Your task today, is to identify the types of numbers we see and use in our daily lives and classify them.  Numbers are everywhere, let's take a closer look!

With your partner, on your paper (one per group), jot down three events in which you have used numbers this week (outside of math class).

• Why were these numbers useful?
• What did these numbers allow you to do?

You are going to research the different types of numbers in the number system. (Real Numbers, Rational Numbers, Irrational Numbers, Natural (Counting) Numbers, Integers, Whole Numbers)

You will create definitions and provide at least 5 examples for each number type.

Once you have your definitions, you will complete your 'Number System Map' based on the information you gathered.  You will then color your map and answer the conclusion questions on your paper.

Process

Step 1:  With your partner, identify three events this week that required you to use math and answer the given questions.

Step 2:  Research the different types of numbers in the Number System.  (Real Numbers, Rational Numbers, Irrational Numbers, Whole Numbers, Natural (counting) Numbers, Integers)

• Form a definition
• List at least five examples for each type of number

Step 3: Using your research complete the "Number System Map"

Step 5: Complete the conclusion questions on your paper.

Evaluation

5 point assignment.

Make sure you have followed all steps.  The assignment is due at the end of class.  If you need to, you can answer the conclusion questions at home.

Conclusion

You now have a complete Number System Map to help you easily identify and classify types of numbers.  This map will be useful to you, be sure to take good care of it!
