**Lesson 9.2 The Real Number System**

Objective - To classify and identify numbers within the real number system.

**Understanding Rational and Irrational**

“Makes Sense” “Doesn’t Make Sense” Rational Numbers Irrational Numbers -Any number that can be written as a fraction. -Non-terminating and non-repeating decimals. fractions -can’t be written as a fraction. wholes integers terminating decimals repeating decimals

**Sets of Numbers Naturals - Natural counting numbers. { 1, 2, 3… }**

{ 1, 2, 3… } Wholes - Natural counting numbers and zero. { 0, 1, 2, 3… } Integers - Positive or negative natural numbers or zero. { … -3, -2, -1, 0, 1, 2, 3… } Rationals - Any number which can be written as a fraction. Irrationals - Any decimal number which can’t be written as a fraction. A non-terminating and non-repeating decimal. Reals - Rationals and irrationals.
