Each form of a linear equation has its purpose — pupils just have to find it. Building on the previous instructional activity in the series, learners examine point-slope and standard form. Using point-slope form, pupils write the...

Reinforce the concept of probability with a series of lessons highlighting the idea of likelihood, probability formulas, relative frequency, outcomes, and event predictions. The collection is made up of four lessons offering informative...

Explore nonlinear systems through graphs and algebra. High schoolers begin by examining the different types of quadratic functions and their possible intersections. They then use algebraic methods to solve systems containing various...

Individuals create a GIS data layer in Google Earth that displays information about where one might find seven different cryptids. The class members research to find data on cryptid sightings they can include in their data...

This is a very brief look at the rhombus, which is a quadrilateral shape with four equal sides. Features include a JavaSketchpad that allows you to manipulate the shape.

This site explains what a minor is relative to matrix manipulations and gives insight on how to use the program "Mathmatica" involving minors.

Allotropes of carbon are described, and 3D models that can be manipulated are included for diamond, carbon, and fullerenes.

Explains how to perform matrix multiplication, including how to perform products on two block matrices. Also has links to related topics.

Simulation of a Lorenz attractor which is shaped like a butterfly. Manipulate the image and observe from all sides as the orbits about two fixed points are drawn.

Did you learn to calculate using a 7-foot-long slide rule? Did you learn about the properties of numbers using brightly colored Cuisenaire rods? Ever wonder who invented the graph paper you used in geometry class? Go back to the...
