In this interactive, use logic to solve three riddles involving high-jump performers in a flea circus. Then, using knowledge of inequalities, place the fleas in the appropriate range on a vertical number line. Numbers are randomized so...

This activity provides an opportunity for students to examine how to find solutions to linear inequalities by graphing.

Resources to help you plan classroom instruction on absolute value inequalities: a lesson with several examples and step-by-step solutions; a six-question quiz with answers; and a teacher resource with guidelines for setting up and...

A good site with a brief explanation of how to graph inequalities.

[Free Registration/Login may be required to access all resource tools.] Solve inequalities by isolating the variable and graphing the solution.

This lesson focuses on developing a way to cross all 7 Bridges of Konigsberg without crossing any of them more than once. Euler discovered it was impossible, but he developed the idea of using graph theory to determine if it would be...

HSA-CED.A.1: Interactive resource which create equations and inequalities in one variable and use them to solve problems. Include equations arising from linear and quadratic functions, and simple rational and exponential functions....

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.

Discover how to graph linear inequalities by taking a look at an example and a video lesson.

Students create linear inequalities and systems of linear inequalities on a coordinate plane. This is like a graphing calculator with advanced viewing options.

Students will use two different methods to determine the densities of a variety of materials and objects. The first method involves direct measurement of the volumes of objects that have simple geometric shapes, while the second uses the...

Given a real-world situation that can be modeled by a linear function or a graph of a linear function, the student will determine and represent the reasonable domain and range of the linear function using inequalities.

This site shows charts, graphs, and information from more than 70 agencies in the United States Federal Government that produce statistics of interest to the public.

This is a site that explores social inequality. Includes tables and graphs to allow visual representations of the distribution of income and wealth. Also includes links to other sites.

A tutorial on quadratics presents topics including: factoring and solving quadratics, graphing quadratic functions, using completing the square and the quadratic formula to solve functions, the discriminant and conjugates. Plenty of...

An interactive graph that predicts how many years until more than two dozen natural resources (e.g., chromium, oil, tin, coal, etc.) are depleted, based on current production rates or production that grows each year. Use the slider at...
