When is the last time you assigned your students only one problem? This seemly simple problem requires learners think like a mathematician and reason about how to solve this compound inequality in one variable. More than just using...

This resource is part of a series which expects participants to be familiar with graphing inequalities on a number line. It is a word problem that asks your class to graph a discrete solution set and interpret it in the context of an...

Discover how to solve systems of inequalities by graphing. An informative video shows pupils how to determine the solution set after graphing each inequality of a system. To finish, a worksheet gives them a chance to practice this skill.

Often inequalities exist in many real-world contexts but young math learners struggle with understanding how to represent that relationship in a simple equation using an inequality. This activity focuses on the basic concepts by using...

Your young boaters will enjoy writing and solving inequalities, and representing the solution graphically in this task set in the context of renting a boat.

Keep your pets slim, trim, and healthy using mathematics! Pupils use a linear programming model to optimize the amount and type of food to provide to a pet rabbit. They model constraints by graphing inequalities and use them to analyze a...

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...

Develop an understanding of things that are not equal. The video demonstrates three types of questions involving inequalities as a review for the General Certificate of Secondary Education math assessment. Pupils work through the...

Provide class members with an opportunity to practice reasoning. A resource contains six skill-based items aligned to the Common Core. The items require pupils to reason abstractly and attend to precision.

Give the class a mental work out with an assessment task in which young mathematicians compare several gym membership options. They use substitution to calculate the cost for given numbers of months.

Twenty-six problems present a variety of practice solving linear inequalities. 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 Solution" button to...

Practice choosing inequalities that represent a graph.

These examples can help you solve absolute value inequalities. They show each step and are easy to follow. The last example demonstrates how to graph the solution.

Given a two-variable linear inequality, check whether a given pair of values is a solution of the inequality. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video, or receive hints.

Check your understanding of equations and inequalities by completing this multiple-choice practice test. You may use a graphing calculator to solve the problems and check your answers at any given time.
