### About This Chapter

## SBA Math - Grade 8: Algebraic Distribution - Chapter Summary

Distributing with negative signs and understanding fractional powers are among the content items students can see across this Algebraic Distribution chapter. The lessons also prepare students for the SBA Math Grade 8 assessments by targeting:

- The purpose of distributing in math
- The decision of whether to distribute first or add first
- Fractional powers, variables and numbers
- The ways in which negative exponents can be written as fractions
- Distribution with multiple terms

Students can watch these fun, informative video lessons in only about 5 minutes each. Video tags can be used by students to easily pick and choose any algebraic distribution video segments to rewatch before leaving the chapter.

### SBA Math - Grade 8: Algebraic Distribution Chapter Objectives

SBA Math Grade 8 assessments indicate how much a student's aptitude for math has increased in a school year. These assessments are written with the Common Core requirements in mind. Any assessment questions that 8th grade students answer involving algebraic distribution will likely be in multiple-choice format and also computer-adaptive. The practice questions across the Algebraic Distribution chapter's quizzes could resemble SBA Math assessment items that students will come across.

### 1. Why Do We Distribute in Algebra? - Explanation & Examples

What's the purpose of distribution in algebra? In this lesson, we'll find out why we distribute. We'll also look at examples and sample problems that involve basic distribution.

### 2. Distributing First vs. Adding First: Differences & Examples

When we need to simplify an expression, how do we know if we should distribute first or add first? In this lesson, we'll look at when this matters and how to make the best decision.

### 3. Distributing Positive and Negative Signs

It's not just numbers and variables that get distributed. Positive and negative signs can, too. In this lesson, we'll learn how to distribute positive and negative signs correctly.

### 4. Distributing Algebraic Expressions with Numbers and Variables

So, you can simplify an algebraic expression when you need to distribute a number? Great! But what if you need to distribute a variable or a variable with an exponent? Learn how in this lesson.

### 5. Changing Negative Exponents to Fractions

A negative exponent isn't like a normal exponent. In this lesson, we'll learn about negative exponents and how they lead us to fractions. We'll practice with numbers and variables.

### 6. Working With Fractional Powers

If you know what to do with 3 to the second power, then you understand exponents. But what if the exponent is a fraction? Find out what to do with fractional powers in this lesson.

### 7. Distribution of More Than One Term in Algebra

Once we've mastered distributing a single term, it's time to raise the stakes. In this lesson, we'll learn how about distribution involving two, three and even more terms.
