Learners explore the discrete mathematics topic of matrices. The tutorial demonstrates how to add and multiply matrices. Some topics explored are scalar multiplication, multiplication of two matrices, square matrices, and addition of two...

Need some challenging problem-solving work for your students in the following areas: Discrete, Geometry, Numbers, and Code Breaking? This is the place for an enormous database of problems aimed at high school age students. They are...

Site gives four different definitions of a closed set in mathematics. Each of the definitions has at least one link for further clarification. The site also expresses which of these definitions is most commonly encountered.

Optimizations problems with examples, solutions, and links to further explain methods to solve.

Explanation of adjacency matrix and how to construct them with examples.

A well laid-out lesson plan that uses a classroom simulation to show the medicine level in the body over a period of time. Students track on a chart the process of intake/elimination and problem solve what happens to the medicine over time.

An article written for teachers with recommendations on how to present permutations, combinations, and the binomial theorem to students. It contains both useful suggestions about order of presentation and many class examples. A good...

An extensive collection of sites on the topic of Knot Theory. Links to dozens of sites are provided which take the user from the basic definition of KT, through to detailed Applet programs which create knots on the spot. NOTE: Some links...

During this lesson, students will be introduced to interpreting functions. A function is a relationship between two sets: the domain (input values) and the range (output values).

Based off of the hit television show NUMB3RS, this lesson has student find the level of similarity between two different-length strands of DNA. Connections to Djikstra's algorithm are mentioned, and students learn more to follow careful...

Based off of the hit television show NUMB3RS, this lesson introduces students to the chaotic topic of Percolation Theory, in which the major question is "Can you get there from here?" Students use their calculators extensively in their...

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

This Wikipedia site introduces the seven bridges of Konigsberg problem, a classic graph theory problem solved by the mathematician Euler in the 18th century.

Wikipedia provides an introduction and overview of graph theory. In addition to introducing the basic terms, there are related links to classic problems in graph theory such as the traveling salesman problem and Dijkstra's algorithm.

[Free Registration/Login may be required to access all resource tools.] This lesson covers using a graphing calculator and matrices to solve a system of equations.

Based off of the hit television show NUMB3RS, this lesson introduces students to the Art Gallery problem, in which guards must be placed so that an entire area is guarded. This lesson may be used concurrently with Guarding the Goods...

Based off of the hit television show NUMB3RS, this lesson introduces students to the Art Gallery Problem, in which the number of guards necessary to guard a two-dimensional space (the "art gallery") must be found. This lesson keeps the...

Based off of the hit television show NUMB3RS, this lesson introduces students to the Art Gallery Problem, in which cameras must be placed so that the entire area of a floor can be seen. Students use their graphing calculators extensively...

A collection of video lectures from a course reviewing linear algebra with applications to networks, structures, and estimation. Webpage includes thirty-six lectures from a professor at Massachusetts Institute of Technology. Lectures...

The online course consists of educational materials about probability and statistics. Lecture notes, exams, and assignments are included.

These activities use matrix theories to solve real-world problems. Students work in groups with hands-on activities.

Learn to understand graphs and graph theory by playing games from Los Alamos National Laboratory. The site also provides definitions and related links.

Gives a basic introduction to combinations and permutations, highlighting the ideas of counting using replacement versus without replacement, and when order is important versus when order is not important.

Explains the fundamental principle of counting, which is the beginning point for any study of counting techniques such as combinations and permutations.
