Cooperative algebra learners swim from the opening pool problem through inequality-infested waters and into life-altering decisions all within one class period. Modeling a pool scenario with an inequality in one variable opens this lesson, which eventually ends with our swimmers modeling a job choice scenario using an inequality to decide which job is best.

Sports Equipment Set
Many students like to play sports and the equipment that goes with it costs money. The resource sets up an inequality that gives a total amount needed to purchase the equipment and the initial amount of money already obtained. In order to make more money, the subject decides to earn it by washing windows.

Systems of Equations and Inequalities
This is a comprehensive lesson on creating and solving equations and systems of equations and inequalities. Problems range from basic linear equations to more complex systems of equations and inequalities based on a real-world examples. Solve inequalities by graphing on a coordinate plane and use the information to draw conclusions about feasability.

Graphing Linear Inequalities
Looking for a resource that goes beyond just graphing inequalities? Here is one that addresses the need to have learners reason and develop a deeper understanding of the solution set of systems of inequalities. This include writing inequalities, analyzing them algebraically, analyzing them graphically, and also through the use of charts.

Understand that Inequalities Have More than One Solution Using a Number Line
To go on a field trip, Mrs. Robinson’s class needs to raise at least 80 dollars. Given four possible solutions, it is up to your number crunchers to use a number line to figure out which solutions would allow Mrs. Robinson’s class to go on the trip.

It all comes together in this video, in which Sal uses the concepts from his previous videos (inequalities involving adding, subtracting, multiplying, and dividing) and addresses them in several problems dealing with compound inequalities. He successfully takes a high-level, often-confusing skill and makes it easy to understand with his straightforward approach.

Inequalities Using Addition And Subtraction
Beginning a "handful of fairly simple inequality videos," Sal demonstrates a few inequality problems in which mathematicians need to add or subtract. Though he states that his goal is to familiarize viewers with the notation, his problem-solving skills are equally beneficial for even the most advanced pupils.

Two-Step Inequality Example
Solving single variable inequalities is explored in this video. The example that Sal shows here contains fractions, shows the need to reverse the inequality because he multiples by a negative number during his computation, and shows the final result graphed on a number line.
