# Ch 5: Common Core HS Algebra: Exponents and Exponential Functions

Watch our lessons on high school algebra. These lessons meet the Common Core Mathematics standard for exponents and exponential functions (CCSS.Math.Content.HSA-SSE.B.3c).

Standard: Use the properties of exponents to transform expressions for exponential functions. (CCSS.Math.Content.HSA-SSE.B.3c)

Students who have mastered this standard are able to analyze and calculate formulas that feature several different types of exponents. By understanding the five main exponent properties, you will be able to take complex expressions and simplify them into shorter expressions. Some of our video lessons also teach you how to graph exponents.

Lessons in this standard cover concepts such as:

• Identifying the five main exponent properties
• Defining a zero and negative exponent
• Simplifying expressions using exponents
• Explaining an exponential function
• Demonstrating exponential growth vs. decay

Students demonstrate mastery of this standard by correctly solving math problems that feature regular, zero and/or negative exponents as well as being able to detail exponential functions. Mastery of this standard is important if they want to enter a career where they have to chart the growth or decay of a business, service or product.

### How to Use These Lessons in Your Classroom

Here are some tips for how to use these lessons to support instruction in this standard:

#### Zero and Negative Exponent Lessons

Develop a worksheet consisting of negative and zero exponent problems. Display the video lesson 'How to Define a Zero and Negative Exponent.' Assign the worksheet for homework and talk about the results the next day. When going over the worksheet, demonstrate alternative ways that the zero and negative exponents can be displayed.

#### Five Main Exponent Properties Lessons

Exhibit the video lesson 'What are the Five Main Exponent Properties?' Give the students sample problems that follow concepts found in the video lesson. Instruct the students to answer the problems. Spend time discussing the results with the class. Require them to identify which property each problem follows.

#### Growth vs. Decay Lessons

Display exponential growth and decay charts on the chalkboard and pass out graph paper. Have the class watch the 'Exponential Growth vs. Decay' video lesson. Call on students to fill out the charts on the chalkboard. Instruct the students to plot the decay and growth points on their graph paper. Discuss the results and what asymptote means.
