Teach solving absolute value inequalities through inquiry. Groups use their knowledge of absolute value and solving inequalities to find a solution set to an absolute value inequality. Working collaboratively encourages discussion,...

Trinity University offers an overview of the problems of inequality in the education system in the United States. Has links to charts and articles about income and education.

This simulation activity teaches students about the inequities in access to global resources, and our responsibility as global citizens to protect the rights and welfare of people around the world who may be impacted by our economic...

In this activity, students will explore the concepts underlying the Triangle Inequality Theorem by comparing side lengths and angle measures of a triangle. They will use an interactive construction to see why this theorem is true.

In this activity the Students can use Cabri Jr. to investigate the Triangle Inequality Theorm and make conjectures about their findings.

This activity investigates the use of the Inequality Graphing App of the TI-83 Plus/TI-84 Plus to solve a linear programming problem.

One property of a triangle is that the sum of the lengths of any two sides must be greater than the length of the third side. [Requires Adobe Reader.]

Miniature Earth reduces the world's population to 100 to underscore the dramatic differences in wealth, age, faith, education, environment, and health among people who live on this planet. An excellent apply-what-you-know site for...

Find the solution sets of absolute value inequalities like abs(x-3)5 using the equation editor (y=). Focus on finding the boundaries of inequality intervals.

Students write and interpret a linear equation and an inequality with two variables and use the Inequality Graphing Application to map inequalities on a coordinate plane.

Like terms have the same degree variable or are constants. When solving an equation or inequality, like terms must be combined. Knowledge of variable expressions and equations assists in solving problems involving logic.

In this activity, students use linear programming to solve problems involving maximum and minimum values. They use the Inequality Graphing application to solve linear programming problems.

Students learn to estimate the solution set, in real numbers, of a linear inequality using graphical methods on a number line and on a Cartesian (x-y) graph. They also learn how to solve inequalities using tables.

Use the Inequality application to solve linear programming problems.

This activity uses the Inequality Graphing Application to take some of the frustration out of linear programming.It allows students to concentrate on the important part of the lesson, so they can learn the basic concepts with greater depth.

Students solve quadratic inequalities using graphs, tables, and algebraic methods.

Students study quadratic relationships and explore the process of graphing quadratic inequalities and systems of quadratic inequalities. They will solve these inequalities algebraically and graph them on a coordinate plane.

Learners investigate how to solve inequalities. The educational resource consists of notes about the concept, detailed examples, and practice problems.
