Rational Exponents Teacher Resources

Introduce your class to cube roots! You can show them this video, in which an instructor demonstrates how to find the cube root of a perfect cube. While this video is clear and well-made, it is appropriate only for more advanced learners...

"Sal, why do we care? Why must we rationalize denominators?" Acknowledging these (possibly pleading) concerns, Sal explains the reasons behind rationalizing a denominator before demonstrating how to do it several times. Though he admits...

Wow! Here is a handout packed full of tips and worked-out solutions to supplement instruction on fractional exponents. The lesson introduces and thoroughly explains the Algebra II concept, and closes with a...

A neat and organized formula handout makes the circle go round, doesn't it? Full of higher algebra topics, formulas and rules, graphs and definitions—there is a way to support everyone in Algebra II or Pre-Calculus. 

Create a human fraction to learn about division of exponents. Scholars develop the rule for division of exponents by being part of a human fraction to explore and justify the rule. They also consider zero exponents and negative exponents.

Don't just use a fraction of this resource ... use it all. Learners first investigate patterns to determine how to deal with fractional exponents. Individuals then evaluate expressions involving fractional exponents.

The 15th installment of a 35-part module is a mid-module assessment task. Covering concepts in the first half of the module, the task acts as a formative assessment, providing you with valuable information on how learners are doing.

Write, graph, and model all things linear and exponential. Building on the previous module in a nine-part Algebra I series, learners compare linear exponential modeling. They write equations, graph functions, and analyze key features.

Here is a video on simplifying radical expressions where the presenter starts with simplifying simple square roots, and quickly develops into looking at more complicated problems. He covers simplifying a variable raised to a power...

Build on pupils' understanding of inverse functions by connecting logarithmic functions to exponential functions. This activity allows individuals to see graphically the inverse relationship between an exponential and logarithmic...

I can multiply, so why can't I add these radicals? Mathematicians use the distributive property to explain addition of radical expressions. As they learn how to add radicals, they then apply that concept to find the perimeter of...

A six-day unit for algebra II on exponential and logarithmic functions builds upon Chapter 12 of Merrill Algebra II with Trigonometry; Applications and Connections. The text provides assistance in the depth of instruction...

Help learners study polynomials. They will review how to multiply polynomials either by using the FOIL method if they are multiplying a binomial by another binomial, or by using the distributive property.

In this Algebra II worksheet, 11th graders solve equations involving radical equations.  The worksheet provides an explanation and worked examples.  The two page worksheet contains three problems.  Solutions are not...

Students explore a variety of functions. They recognize and describe functions and use linear functions to describe situations. Students find the domain and range of linear functions and graph rational expressions.

Students use the quadratic formula to solve application problems. The first problem relates to the path of a football thrown from the top of the bleachers. Students compute the time it will take the football to reach certain heights. In...

Students model data using quadratic equations. For this algebra lesson, students simplify and factor quadratic equations. They graph the function using collected data and analyze the parabola.

In this tutorial, you will learn what a rational exponent is and how to complete many tasks involving them. Follow step-by-step instructions and examples, view video explanations, and hone your skills with several practice problems.

An online tutorial which teaches you how to rewrite a rational exponent in radical notation, simplify an expression that contains a rational exponent, and use rational exponents to simplify a radical expression. Works through example...

Twenty problems present a variety of practice applying the various properties of rational exponents in different situations. They are given with each step to the solution cleverly revealed one at a time. You can work each step of the...

Twenty-two problems present a variety of practice working with nth roots and rational exponents. They are given with each step to the solution cleverly revealed one at a time. You can work each step of the problem then click the "View...

This video describing rational exponents and giving examples can be used to help prepare for the SAT. You will learn how to rewrite an expression with a rational exponent in several ways. [8:09]

Here is a site that clearly and thoroughly explains rational exponents. There are example problems with solutions and problems for students to try. Answers to each student problem is hidden until one passes over it with the computer's...

In this lesson on rational exponents, students explore how to simplify exponents that are fractions and negative exponents.
