Discrete Mathematics Teacher Resources

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 "simple" lesson will actually give students a lot to think about. Given a graph, students are to establish how many searchers are needed to find an infinitely fast criminal who is on the...

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.

[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 cameras must be placed so that the entire area of a floor can be seen. Students use their graphing calculators extensively...

MathWorld.com shows many types of discrete math graphs and provides links to related topics.

The choice of graph representation is situation-specific. It totally depends on the type of operations to be performed and ease of use. This reference explains the most commonly used representations of a graph: Adjacency Matrix and...

In this applet, students use the tools to eulerize each graph.

On this site, there are several math problems to explore and solve. Look through some solutions by famous mathematicians and expand your thinking about some interesting math concepts. Teachers of elementary grades may want to use this...

This lesson focuses on Combinatorics, a branch of mathematics which is about counting. It includes 5 sections: Factorials, Permutations, Combinations, Combinatorics and Pascal's Triangle, and Combinatorics and Probability with examples...

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.

Based off of the hit television show NUMB3RS, this lesson has students analyze different networks to determine the maximum flow rate of each network. This is done in the context of power plants supplying the community with electricity....

Based off of the hit television show NUMB3RS, this lesson is an extension on the classic Handshake Problem, in which one discovers how many handshakes have taken place among a group of people (assuming each person shakes everybody else's...

Based off of the hit television show NUMB3RS, this lesson introduces students to critical path analysis (CPA), in which tasks are broken into subtasks with prerequisites. In such a situation, subtasks must be completed in a certain order...

Brief description of Hamiltonian Path and solving the Hamiltonian Path problem.

Critical path analysis is a project management tool used to understand task dependencies and their effect on the project schedule. For this lesson, we show how the critical path can be derived

The mathematical treasure hunt allows young scholars to follow a trail of clues and mathematical problems around the school site; each clue contains a hint to where the next clue is hidden.

Introduction to the Chinese postman problem with diagrams.

A variety of lesson plans offer activities to use when teaching discrete math and election theory. The activities get students involved in group work to apply the concepts.

These discrete math activities utilize the concepts of iteration and recursion. Students work in a group to solve real-world problems.

A series of activities in fair division allows students to work in groups on discrete math concepts. Tips are included on how to incorporate the activities into other math areas, including Algebra and Geometry.
