Lesson Summary:

In this lesson, you'll learn all about the real number system and its different classifications. Starting with natural numbers, whole numbers, and integers, you'll follow along with Mr. Perez as he marks a real number line with these numbers. Then, he'll explain rational numbers, which include fractions with decimal representations that either terminate or repeat in a pattern. Finally, he'll touch on irrational numbers, which have decimal representations that go on forever with no pattern. With examples of both rational and irrational numbers, you'll leave this lesson with a better understanding of the real number system as a whole.

Lesson Description:

Classifying real numbers and talking about the different types of real numbers by using the real number line.

    This lesson explains all of the sets of numbers that a real number could belong to. All numbers that belong to each set are explained and shown on a number line. Several example numbers are explained for each set.

    Fuzzy video kind of hard to read the words that pop up. Kid in desk was kind of distracting. Gives me good information though.
