Solving Inequalities Teacher Resources

Learners multiply inequalities by negative. In this algebra lesson, students solve inequalities and graph their solutions on a number line. They pay close attention to the negative consequence, which causes the sign to flip.

In this absolute value worksheet, high schoolers solve absolute value equations. They solve inequalities with absolute values. This four-page worksheet contains 24 problems.

In this inequality worksheet, learners solve inequalities on a coordinate plane by graphing. The linear equations contain two variables. This one-page worksheet contains ten problems.

For this SOL worksheet, students solve inequalities, identify equivalent fractions and graph polynomial functions.  They find the geometric means and compute average rates.  This eight-page worksheet contains 20 multiple-choice...

In this Halloween crossword puzzle worksheet, 4th graders will solve more than 40 clues to complete the puzzle. Words include "trick" and "mask".

In this domain and range worksheet, students solve inequalities, determine the domain and range for a function, identify the limits, and sketch graphs of a function. This two-page worksheet contains nine multi-step problems.

For this one variable inequalities worksheet, middle schoolers circle the correct solutions, complete graphing problems, and solve for the variables. Learners complete 37 problems.

Ingrid got some good advice from her father about building a bridge out of pasta. Now she has to do some calculations to build a strong pasta bridge. Figure out how tall she can build her bridge based on a given length. Two given values...

It just doesn't seem right to lose points when answer a question incorrectly. Well, that's what this word problem is all about. So calculate how many incorrect answers the team gave. Don't forget to flip the inequality when dealing with...

In order to solve this inequality use the addition property of inequality to isolate the variable. Don't forget that these are decimal numbers. So be sure to line up the decimals according to the rules of adding decimals.

Use the subtraction property of inequality to solve this problem. It's just a one-step solution and then the instructor shows how to write the answer in set builder notation.

In this math worksheet, students solve inequalities. Four problems involve negative values for the variables. Inequalities involve two or more steps to solve. The final two problems are word problems.

You might be familiar with graphing a quadratic equation but what about a quadratic inequality? This video walks you through an example of graphing a quadratic inequality by first graphing a quadratic equation using factoring to find the...

If your class is studying inequalities, consider this video. The focus is on solving a decimal inequality that has negative numbers in it. A lecturer works through an example problem, commenting on the steps and properties necessary to...

Combining the skills from the previous videos, particularly inequalities and absolute values, Sal works to solve several new sample problems. He encourages watching the video "over and over," which is good advice for mathematicians of...

Go over how to solve a compound inequality and graph it with this video. The video is clear and concise. A lecturer solves a compound inequality and graphs it on the spot, explaining each operation in detail. Great for in-class or...

You've got a linear system of inequalities? You need to solve it by graphing? No sweat. Make sure that each equation is in slope-intercept form and then graph each equation. Is it a solid line or a dashed line? Which side of the line...

Broken lights at the skating rink? Are there enough not broken to be able to see well enough to skate? Set up this real-world word problem and find the total number of lights in the skating rink. Two given values and one variable. Solve...

You've got a linear system of inequalities? You need to solve it by graphing? No sweat. Make sure that each equation is in slope-intercept form and then graph each equation. Is it a solid line or a dashed line? Which side of the line...

A word problem that needs to be written as an inequality to solve. This expression seems pretty straightforward and only takes one step to solve. But wait, the division property was used with a negative number so the inequality sign has...

Just when a young mathematician starts to feel comfortable turning word problems into linear equations, shake things up and throw inequalities in the mix. This excellent, instructive presentation takes the steps for solving an...

A word problem with one variable and two given numbers. This word problem seems doable from the start. Wait, it's an inequality. Don't worry about that piece, just get the expression written and do the math. Watch this video and see how...

Applying the multiplication property of inequality is just like working with linear equations. What is done on one side of the equation needs to be done on the other side of the equation. So this rule can be applied to inequalities. In...
