Learning Objective: Describe and distinguish between rational and irrational numbers
Card Sort • Your table will be given an envelope full of numbered cards. • Put these cards into groups in the best way you see fit. • Be prepared to justify WHY you sorted them the way you did.
Gallery Walk • You will each receive 2 sticky notes. • Title one “I notice…” and the other “I wonder…” • Walk around and look at the way each table sorted their cards. • Respond to any table with each of your sticky notes.
Share as Class • Each table will read their sticky notes and share how they categorized their numbers. • Is there anything you would change?
Notes: Real Number System • Examples of Rational Numbers: • Examples of Integers: • Examples of Whole Numbers: • Examples of Natural Numbers: • Examples of Irrational Numbers:
Definition • Create your own definitions of the following: • • • Rational Numbers Integers Whole Numbers Natural Numbers Irrational Numbers:
Actual Definitions: • Rational Numbers: Any number that can be written as a fraction (terminating decimals, repeating decimals, fractions, perfect squares, whole numbers) • • Integers: Positive and negative whole numbers, including zero (number line) Whole Numbers: Positive numbers on the number line, including zero Natural Numbers: Counting numbers Irrational Numbers: Non-terminating, non-repeating decimals
Reflect! In your own words, explain the difference between rational and irrational numbers. Give examples for both.
Resort Your Cards • Now you will resort the cards into either Rational or Irrational Numbers. • We will check your work as a class. • Then, fill in the graphic organizer with the Rational/Irrational Numbers.
