Solving For One Unknown

You can't go wrong with a lesson plan that involves candy! Learners solve and graph one-variable inequalities and use candy to graph the solution. Individuals associate open circle graphs with life savers and closed circle graphs with...

Lets keep the system working and show learners the three ways to solve linear systems of equations. Each method includes step-by-step instructions to work their way through the problem. The same problem is used for each method to show...

What does solving an inequality have in common with solving an equation? Almost everything! A math resource focuses on the one exception. The examples lead learners through the steps of solving an equality when multiplying or dividing by...

Turning absolute value inequalities into compound inequalities and graphing them is an algorithmic skill that many young algebrists memorize instead of working to understand. This presentation really emphasizes the how's and why's of...

You know how to find absolute values and you know how to solve inequalities — but what happens when these two concepts are in the same problem? A YouTube video first reviews absolute values and moves on to solving absolute value...

With his trusty graphing calculator, Sal begins his lecture on solving quadratic functions by graphing. The video is a good way to show young mathematicians not only how to use the graphing calculator (which Sal describes as "archaic"...

Introduce compound inequalities and the way mathematicians write them with a concept video. The problem explanations detail how to write, solve, and graph compound inequalities in one variable.

Approach inequalities in a new way with this video! This video gives step-by-step instruction on how to solve a 2-step inequality and then graph the answer. Learners could use this video as a reference as they do homework, or you might...

Approach inequalities in a new way with this video! This video gives step-by-step instruction on how to solve a two step inequality and then graph the answer. Learners could use this video as a reference as they do homework, or you might...

It would be an inequality if you stopped at linear equations and didn't graph linear inequalities too. The last video in the series combines the idea of compound inequalities with linear systems to create a new type of system. Learners...
