About This Chapter

The WEST Middle Grades Mathematics certification exam has been replaced with the NES Middle Grades Mathematics test. In preparation for this exam, be sure to review what you know about solving and graphing inequalities with the lesson videos, worksheets and quizzes of this chapter.

NES Middle Grades Mathematics: Inequalities - Chapter Summary

Watch the lesson videos of the chapter to review the steps in graphing and solving different forms of inequalities so that you will be prepared for related question on the National Evaluation Series (NES) Middle Grades Mathematics. If at any time you come up with any questions regarding the material of this chapter be sure to ask our expert instructors for clarification so that you will be able to accurately answer question about:

  • Graphing 1- and 2-variable inequalities
  • Compound inequalities and systems of inequalities
  • Finding and graphing the absolute value of inequalities
  • Translating math sentences into inequalities
  • Solving one-step and two-step linear inequalities

After you have watched these lesson videos, be sure to complete the lesson worksheets and quizzes that accompany them to fortify your understanding of the material you reviewed. Using your quiz results, find topics you don't fully understand, then improve your understanding of these topics by returning to the areas of the lesson videos in which they were discussed with video tags.

What is an Inequality?

1. What is an Inequality?

Deciding how to spend your money can be a tricky thing. Should you save it, invest it, or enjoy it? Learn how inequalities can help you make your decision!
How to Graph 1- and 2-Variable Inequalities

2. How to Graph 1- and 2-Variable Inequalities

So an inequality is just an equation with a less than or greater than symbol. But what is the difference between 1 and 2 variable inequalities? What does have a greater than or equal to symbol change? When do you use a number line instead of a coordinate plane? Get those answers here!
Set Notation, Compound Inequalities, and Systems of Inequalities

3. Set Notation, Compound Inequalities, and Systems of Inequalities

In this lesson, we'll explore the conditions of compound inequalities and learn how to express them using set notation and interval notation. Test you knowledge afterward with a short quiz.
Graphing Inequalities: Practice Problems

4. Graphing Inequalities: Practice Problems

If you're already pretty familiar with what inequalities are and just looking for a place to practice your skills, this is the place. This lesson covers topics like 1-variable, 2-variable, compound, and systems of inequalities.
How to Solve and Graph an Absolute Value Inequality

5. How to Solve and Graph an Absolute Value Inequality

Taking two skills and combining them to make a more complicated problem is a classic tactic in mathematics. If you feel confident with absolute values and inequalities, see if you can tackle them with their powers combined here!
Solving and Graphing Absolute Value Inequalities: Practice Problems

6. Solving and Graphing Absolute Value Inequalities: Practice Problems

Solving and graphing absolute value inequalities brings a lot of different skills together in one place. The practice problems in this video will give you a good chance to see more examples of absolute value inequalities but will also test your general algebraic knowledge.
Translating Math Sentences to Inequalities

7. Translating Math Sentences to Inequalities

Watch this video lesson to learn how you can easily translate math sentences into inequalities. Once you know how to do this, solving word problems becomes that much easier.
Solving One-Step Linear Inequalities

8. Solving One-Step Linear Inequalities

In this video lesson, you will learn how you can solve any kind of linear inequality that only requires one step. Learn when you need to subtract, when you need to add, when you need to multiply, and when you need to divide.
Solving Two-Step Linear Inequalities

9. Solving Two-Step Linear Inequalities

After watching this video lesson, you will be able to solve any kind of linear inequality problem where you only have to perform two steps. You will know in what order to perform each step and you will know just what kind of operation you need to do.
