This App helps students build number sense skills and gain confidence at math by hand. Review how to perform algorithms for the four basic operations (Addition, Subtraction, Multiplication, and Division). A step-by-step mode emphasizes...

Based off of the hit television show NUMB3RS, this lesson has students think about fair way to divide a quantity into even parts. Different algorithms are presented, including "I cut, you choose," and students are to choose which...

The connected machine is a single function that takes an input, runs it through the network inside and produces an output. You control a network of function machines along with the input and the operation performed by each machine to...

Imagine 31 numbers have been organized in ascending order in a list by a computer program. Now the program has to find a number in the list, but it can only look at one number at a time. Is it easier to find the number now, than if they...

How would you look for a book in a library if the books were sorted in alphabetical order? Is that easier than if they were out of order?

Learn about Big Theta Notation in computer programming.

An advanced investigation of Greatest Common Factors (Divisors) and a look at related algorithms and properties) comutative, associative, and more). Contains links to relevant topics.

This activity should help kids to perform quick computations using mental math, become less reliant on calculators for computation, and remember algorithms for common math problems by using repetition and practice.

This StudyCards set uses guided discovery concepts to develop ideas for functions operations, building from rational expression multiplication and division algorithms.

This App allows students to review how to perform algorithms for the four basic operations. The three modes - the step-by-step mode, fast mode, and the Missing Pieces game allows students to learn, review, and understand the concepts for...

In this activity, students make use of a visual representation for dividing fractions. They also discover the numerical algorithm used to divide fractions.

In this activity, students attain a basic understanding of numbers and number operations, developing number sense, and gaining fluency in arithmetic computation. They also learn to use the calculator to explore the mathematical...

In this activity, students develop algorithms for generating and generalizing patterns related to triangle and square geometric models.

Based off of the hit television show NUMB3RS, this lesson introduces students to the lesser-studied topic of Flock Theory. The lesson is framed in the context of groups of birds, which follow a few simple rules. By using this algorithm,...

This App helps students practice multiplication and division with decimals in a fun environment. Students use this App to learn standard multiplication and division algorithms as well as understand topics such as scientific notation, the...

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.

Brute computing force alone can't solve the world's problems. Data mining innovator Shyam Sankar explains why solving big problems is not a question of finding the right algorithm, but rather the right symbiotic relationship between...

Can the way you speak and write today predict your future mental state, even the onset of psychosis? In this fascinating talk, neuroscientist Mariano Sigman reflects on ancient Greece and the origins of introspection to investigate how...

A description and demonstration of the heap sort algorithm.

A description and demonstration of the quick sort algorithm.

Brain-machine interfaces (BMI), or brain-computer interfaces (BCI), is an exciting multidisciplinary field that has grown tremendously during the last decade. In a nutshell, BMI is about transforming thought into action and sensation...

Can you work out which order these thirteen nations finished in after competing? This activity presents an exercise in strategic thinking, accessible to lower secondary students (but hinting at the more advanced mathematics of sorting...

Students identify a pattern in the usage of the articles 'a' and 'an' and then write an algorithm that others can follow to correctly use these two indefinite pronouns, and they identify possible exceptions the general rule.
