This resource presents a biography of Bohr, including many personal tidbits, as well as a substantial treatment of his scientific work. Several interesting quotes by and about Bohr are included. It also links to several other sources.

What a great way to make math fun for your elementary students! Learning happens almost by osmosis by using this interesting game that uses stories, a graph (the kind of graph defined in the branch of mathematics called Graph Theory),...

Let's Go to the Mall! is designed to help learners understand the connection between various kinds of combinations (multiplication principle and choose numbers) and permutations.

The Amazing Mathematical Object Factory allows you to review many combinatorial objects by producing lists of mathematical objects. This game helps make discrete mathematics more accessible. Combinatorial objects are studied in discrete...

Response to Intervention (RTI) is a complex subject and states and districts have a lot of discretion with the implementation of this three-step, research-based approach to intervention and placement. Learn about some of the common...

In this activity, students will read about the changes in the "new money" and then create a graph to represent various combinations of currency produced. This activity provides an excellent example of discrete, real-world data.

Students use sample data to approximate models with the Transformation Graphing Application. They are introduced to the idea of discrete data sets being used with continuous function models. They also identify non-zero asymptote form of...

Based off of the hit television show NUMB3RS, this lesson has students find the probability of chips falling into each bin of a Galton Board (also known as a quincunx or Plinko board), and then graphing these data to form a normal curve....

Based off of the hit television show NUMB3RS, this lesson introduces students to the Knapsack Problem, a discrete mathematics situation in which a knapsack is to be filled with a series of objects, each with various weights, sizes, or...

Students will solve discrete math problems involving permutations, factorials, and combinations. Students are responsible for deciding which is appropriate to solve a given word problem.

Klaus von Klitzing is a Nobel laureate who won the award in 1985 for his discovery of the quantized Hall effect, sometimes referred to as the quantum Hall effect. Von Klitzing's discovery resulted from his work exploring a phenomenon...

The forests of Western North Carolina are threatened by a wide variety of environmental stressors and disturbances, such as insects, disease, invasive species, drought, fire, hurricanes, tornadoes, and ice storms. A stressor is any kind...

[Free Registration/Login may be required to access all resource tools.] This Concept introduces students to discrete probability distributions.

Learners explore the discrete mathematics topic of matrices. The tutorial demonstrates how to calculate the inverse of a square matrix. The activity includes examples with 2 by 2 and 3 by 3 matrices.

The task provides a context of "random walking" to calculate discrete probabilities and represent them on a bar graph. Aligns with S-CP.B.9.

For this task, a person moves left or right one unit on a life-sized number line based on the toss of a coin. The task involves interpreting a function in a non-standard context and provides an opportunity to compute some probabilities...

Learn how to graph the inverse of a series of discrete and continuous. Also learn how to determine whether the inverse of a function is also a function.

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...

When you witness an injustice, remaining silent or acting as a bystander is an active choice that is an impediment to justice. In this lesson students will have the opportunity to examine the consequences of remaining silent specifically...

NOVA Addiction is a film that explores the impact of the opioid epidemic on individuals and society, examines the neurobiology of opioid addiction, and discusses current harm reduction approaches and treatments and how they might be...

Dozens of statistical terms are defined and illustrated in this glossary.

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.

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...
