Learn to produce coastlines in 2D and mountains in 2D and 3D by adapting ideas related to the construction of fractals. Introductory mathematical issues in random number generation are discussed. Java applications allow

interactive exploration.

The dihedral group D8 (sometimes called D4), the group of symmetries of the square, is one of the simplest finite groups. In these three mathlets, we will explore different aspects of this symmetry group to get a better understanding of its structure.
An article presenting a way that students of calculus and linear algebra can use both artistic and mathematical abilities to transform ordinary photographs into interesting pictures having mathematical content
The Sampler software simulates samples from a wide variety of populations in a manner that is ideal for classroom presentations. The software is written in Java and runs within your web browser.
An article about software tools that have been developed in Geometer's Sketchpad to aid in constructions in non-Euclidean geometry
This Java applet consists of a game with three concentric wheels onto which the students place three copies of the numbers 0 through 6. The wheels are spun and payoffs are made for sums of 7 and 11. Probability and expected value questions are explored.
