FSA - Grade 8 Math: The Real Number System Objectives
The Florida Department of Education administers the FSA - Grade 8 Math test to measure the academic development of 8th-grade students across the state. The material in this study chapter is relevant to the section of the test called Statistics and Probability and The Number System, which makes up 18% of the test. The computer-based test is composed of three types of questions: multiple-choice, open-answer, and technology-enhanced (interactive).
1. What are Rational Numbers? - Definition & Examples
In this lesson, we will learn about rational numbers and their characteristics. We'll discover what they are, what they aren't and how to distinguish them from other types of numbers.
2. Decimal Expansion of Rational Numbers
Numbers can be represented in several different forms, including fractions and decimals. In this lesson, learn about decimal forms of numbers and how to convert repeating decimals to rational numbers.
3. Graphing Rational Numbers on a Number Line
Number lines have many uses both in mathematics and everyday life. This lesson will teach you how to graph numbers on a number line and give real-world examples of how to use number lines.
4. What are Irrational Numbers? - Definition & Examples
Irrational numbers may not be crazy, but they do sometimes bend our minds a little. Learn about common irrational numbers, like the square root of 2 and pi, as well as a few others that businessmen, artists, and scientists find useful.
5. Estimating Square Roots
Inverse operations are mathematical operations that undo each other. The square root is the inverse of the squared (or multiplying a number by itself) operation. There is an easy method for estimating the square root of a number, which you will learn in this lesson.
