Young scholars use the inequality theorem to solve triangles and their properties. In this geometry lesson plan, students are given spaghetti of different lengths and asked to create triangles. They conclude the necessary length needed to make a triangle and relate it to the inequality theorem.
Students examine poverty and inequality in America. In this current events instructional activity, students read the provided articles "Poverty," "Inequality Growing in America," "Inequality: Views on Causes, Effects, Remedies," and "Theories on the Origins of Poverty and How to Reduce It." Students respond to the provided discussion questions.
Students examine the concept of inequality. They compare and contrast vertical and horizontal inequality and identify methods on how inequality is measured. They research trends of inequality in the United Kingdom.
Students explore the concept of linear inequalities. In this linear inequality activity, students graph linear inequalities using Microsoft Excel.
In this online interactive philosophy worksheet, high schoolers respond to 35 multiple choice questions about Discourse on Inequality by Rousseau. Students may submit their answers to be scored.
In this graphing inequalities learning exercise, students create graphs of algebraic expressions containing inequalities. This two-page learning exercise contains explanations and examples prior to the exercise. The first page is a contains definitions, and the second page contains approximately 11 problems.
This is a comprehensive instructional activity 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.
Solve algebraic equations and inequalities. Work in small groups to understand and solve a number of simple algebraic equations and inequalities. Then create a PowerPoint presentation that includes the problems solved and the method used to solve each one. Each group will present their findings and methodology to the class. 
What makes the pan balance tip? This is the question your number crunchers will be asking. Given a specific set of values, show learners visually which numbers make the inequality true. It is a simple resource that uses substitution to apply reason to one-variable inequalities. It emphasizes that correct answers are not limited to the solutions given.
Students discuss graphing inequalities on a number line. They solve one step inequalities. Students work simple interest problems. They work independently on a set of problems. Students pause in their independent work to discuss ways of solving several problems as a class.
This video highlights a problem your pupils will find interesting. Instead of trying to solve an inequality for a value or set of values, this problem requires that the learner construct an inequality and interpret its mean by reasoning abstractly. This might make a great problem for a small group activity.
This inequality word problem would make a good warm-up activity for a class studying single variable inequalities. This video creates and solves an inequality based on a short word problem about unit cost.
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. This problem that is modeled in the video will help your learners understand that an inequality with one variable has more than one solution.
This video shows a basic real-world example of absolute value. One must find the range of acceptable values given a specified margin of error.
In this equations and inequalities review worksheet, 11th graders solve and complete 100 various types of problems. First, they solve each equation using the quadratic formula or completing the square. Then, students solve using matrices and Cramer's Rule. In addition, they write the equation of a various types of lines described.
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 show it as a warm-up the day after you teach this concept. Overall, a great resource.
A direct instructional video of how to solve an inequality when you have the same variable on both sides of the inequality sign, this resource could be used in class or at home.
Is your class working on inequalities? If so, you might be interested in this video. This well-made video shows how to solve an inequality by dividing by a positive number. An instructor details each step, writing out her work as she solves the inequality. You might consider using this as a supplementary material for the whole class or select learners who need more support.
Solve this real world word problem in just one written step. The original inequality is a division problem, so to solve it, use the multiplication property of inequality. Was the problem solved by multiplying a negative number? Yes! So don't forget to flip the inequality sign in the solution. Watch this video for a closer look at how to do that.
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 this example, perform multiplication on each side of the inequality.
