Demos with a positive impact. A collection of visuals for much math taught from the precalculus level and up. DEMOS with POSITIVE IMPACT is a project to connect mathematics professors with effective teaching tools. As instructors we use a variety of techniques to try to get important ideas across to students. This project focuses on demonstrations that use some form of instructional technology.
Saltire's Geometry Gallery is a collection of
Java applets showing interesting geometry configurations. All applets
are dynamic in that user input can cause the configuration to
change. In some cases, points can be dragged. In other cases
dimensions can be changed via edit controls. Some of the applets
feature animation.

MathPages A collection of advanced math and physics miscellany. Nicely done and well worth a visit.
The makers of Mathematica, Wolfram Research and Eric Weisstein maintain a HUGE site for things math.
Maths Thesaurus Presently the thesaurus contains definitions of 4019 concepts, with 14583 cross-references between concepts. It is this richness of crossreferencing which leads us to call the project a thesaurus of mathematics; it is much more than an alphabetical list of words and their definitions.

THE MATHEMATICAL ATLAS This is a collection of short articles designed to provide an introduction to the areas of modern mathematics and pointers to further information, as well as answers to some common (or not!) questions. The material is arranged in a hierarchy of disciplines, each with its own index page ("blue pages"). I especially like the section on what a kid should know about mathematics in each grade from K-12.

Purplemath
Provides a text-based explanation of math topics and offers practical
tips and common mistakes. It covers a number of algebra topics in a
similar format (Elizabeth Stapel, Braden Bryce Publishing, Chandler,
AZ)
InterMath is a professional development effort designed to support
teachers in becoming better mathematics educators. It focuses on
mathematical investigations that are supported by technology. InterMath
includes a workshop component as well as an ongoing support community
that includes a lesson plan database and a discussion board.
The Data and Story Library
DASL (pronounced "dazzle") is an online library of
datafiles and
stories
that illustrate the use of basic statistics methods. We hope to provide
data from a wide variety of topics so that statistics teachers can find
real-world examples that will be interesting to their students. Use
DASL's powerful search engine to locate the story or datafile of
interest.

NATIONAL
LIBRARY OF VIRTUAL MANIPULATIVES
This is a three-year project to develop a library of uniquely
interactive, web-based virtual manipulatives or concept tutorials,
mostly in the form of Java applets, for mathematics instruction (K-12
emphasis). The project includes dissemination and extensive internal and
external evaluation. Our Utah State University team is building
Java-based mathematical tools and editors that allow us to create
exciting new approaches to interactive mathematical instruction. Try

Eric Weisstein's World of Mathematics (MathWorldTM) is the web's most complete mathematics resource, assembled over more than a decade by internet encyclopedist Eric W. Weisstein with assistance from the mathematics and internet communities. Unfortunately, he is in court over copyright issues and therefore the site is so far deactivated.

Cornell University's pick of the best of the Web
Cornell Theory Center Math and Science Gateway
Just about everything we teach in high school math is located at this site, from graphing to functions to calculus, etc. I know the explanation is sparse, but there really is just too much to list. It even has on-line worksheets for students to answer questions. The single thing I liked best was given y = x squared + px + q, you can drag the values of p and q and watch the quadratic change in real time.
Below is probably the most extensive mathematics search engine on the entire WWW. Everything else ain't even close. This is The Math Forum. It has Geometry Sketchpad information as well as Ask Dr. Math (a feature which allows you to pose your unanswered questions to experts.

Huge Gaping Holes in the Foundations of Mathematics
Here is a site that challenges you to prove the Pythagorean theorem by shearing, rotating, and translating the given shapes.
Think of a polygon as a chain of rigid rods connected to each other in two dimensions with flexible joints. Start with any configuration, no matter how complex and intricately indented, or crinkly. Can you always find a sequence of moves that removes the indentations—unfurling the polygon into what mathematicians describe as a convex shape, like a triangle—without ever letting the rods cross each other? This is an article on the proof of polygonal unfolding and this is a really cool page with animated GIFs that show the theorem in action. It also has a game you can plan which deals with robotic arms. I thank Guy Fain for sending me the site.
