This page discusses sets and set theory in mathematics and probability, and it discusses the notation and properties of sets.

This page gives a brief discussion of the intersection of sets in mathematics and probability.

Checks understanding of the union, complement, and intersection of sets. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Help your students identify sets and intersections of sets with this musical activity. Using the concept of key signatures, students will learn that scales are sets of notes. Included with this lesson plan are downloadable worksheets and...

Assess understanding of sets by matching each set notation with its corresponding set.

This site responds to an inquiry about what the intersection of sets is. Dr. Math gives an example using cars with certain attributes and then the intersection of these sets.

Get independent practice working with the intersection and union of sets. Each incorrect response gets a text box explanation and another try. Correct responses are confirmed.

This resource explains concepts related to set notation and gives examples for each.

For this task, students are shown the graphs of two equations, with areas bounded by their lines and intersections shaded in different colors. They are asked to write a system of equations or inequalities for each shaded area and explain...

Interactive assessment in which the solution set of an equation is found. Combines equation solving skills with set notation, introduces empty sets, intersections, subsets of real numbers (rational, integer, prime, etc.).

Find a quick, concise explanation of operations on sets. Examples are given and clearly explained.

Solve a number riddle by finding the point of intersection for two lines. This video focuses on finding the solution for a system of equations, they are represented as an algebraic expression and a set of linear equations that are...

This set of questions pertains to systems of linear equations. Students are asked to determine the number of solutions and to find points of intersection. These are multiple choice problems with solutions included.

This math site explains disjoint sets via example and definition. This site has links to related topics.

This page provides a good explanation of unions of sets in mathematics. It discusses the union of disjoint sets and the probabilities of unions, incorporating probabilities of the two independent sets and their intersection. Discusses...

[Free Registration/Login may be required to access all resource tools.] This Concept teaches students how to find unions and intersections, as well as to calculate the probabilities of of these sets.
