This would be a good reference site for your students if you developed a class web page. It contains information on a variety of math topics including geometry and trigonometry. The Geometry webpage includes an informative introduction to geometry. It also contains definitions of geometric terms as well as theorems and postulates. What I like the most about this site is that it gives a good definition and explanation of proofs. The Trigonometry web page is illustrative and full of examples. I like the fact that it includes brief lessons of geometric history. There are exercises that the students could try to test their understanding of topics in geometry and trigonometry, as well.

This is a nice website that you could refer to on your personal web page for your geometry students. It is an online course that provides the students with review problems and applications of various geometric relationships. There are 70 interactive 'quizes' on the website that the students can take to refresh and deepen their understanding of the lessons presented in class. I believe that this website could complement any geometry class.

This is a very interesting site. What I like about it the most is that it makes a variety of links/connections between Geometry and other disciplines. For example, there is a section of the website that deals with the history of geometry. There are also several activities that you could use during your lessons. For instance, there is a real world activity called School Bus Geometry which I think students could benefit from solving. There is also a glossary of geometric terms on this site which would be helpful for students who may visit the site.

This website presents aspects of geometry in a different fashion. It contains 10 lessons involving tesselations that allow the students to work cooperatively. The site touches on transformations and allows students to explore them hands on. The students are able to create their own tesselations and explore their more creative/artistic side. Check this site out. It could be fun for you and your students.

As the author states, “These pages contain usenet clippings, web pointers, lecture notes, research excerpts, papers, abstracts, programs, problems, and other stuff related to discrete and computational geometry.” The “junk” is nicely sorted into about 25 specific categories, ranging in accessibility from origami to Voronoi diagrams. I was impressed by the variety of resources from which information has been collected and reorganized.

As the author describes, “This page collects various areas in which ideas from discrete and computational geometry ... meet some real world applications. It contains brief descriptions of those applications and the geometric questions arising from them, as well as pointers to web pages on the applications themselves and on their geometric connections.” The applications are divided into categories: pure geometry, design and manufacturing, graphics and visualization, information systems, medicine and biology, physical sciences, robotics, and other (including such surprises as sociology and timber processing). This is a wonderful resource toward which to direct students when they ask, “How am I ever going to use geometry?”

A collection of beautiful, colorful computergenerated images of polyhedra, complete with descriptions. Polyhedra are divided into five categories, from simplest to most complex: Platonic Solids, Archimedean Solids, KeplerPoinsot Polyhedra, Compound Solids, and Stellated Polyhedra. Within each category is a piece of an progressive description which the author uses to tie each class of polyhedra to the previous set(s). Also included is a link to the computer program used to create the images and a link to a primer which describes how to make highquality paper models of the polyhedra. A wonderful launch point for a endofunit discovery lesson on 3dimensional solids.

At first glance, this site appeared to be a wonderful collection of formula pages and diagrams displaying basic concepts of geometry. However, that “collection” turned out to include only two categories: Area/Volume/Surface Area and Circles. These two pages are quite useful, but the page doesn’t include enough material to warrant a bookmark. I plan on sending the author a comment to encourage him to beef up his geometry section; I could use the timesaver of having formula sheets at my fingertips.

The name of the site speaks for itself. The problems are quite good, and typically do not have an exact answer  more often a description of the answer process is desired. For example, this week’s problem contains the following disclaimer: (Here's a hint: the answer doesn't have to be a single number, but tell me as much as you can about the area of the parallelogram. What can it be? I want to know "the answer", which means everything, not just "an answer".) The page contains an archive of previous problems and solutions, and offers prizes to students who consistently submit correct solutions. A wonderful enrichment resource and extracredit incentive, especially for those alwaysdoneearly Type A’s.

This web site is a great one. As the title implies it is completely about the Pythagorean Theorem. It gives a couple different proofs of the theorem, with animations accompanying some of them. It also gives a lot of history about Pythagoras and the theorem. It would be a great resource when introducing the theorem to the class.

This site is not as good or in depth as the previous site about the Pythagorean Theorem, but the proof and animation that is given is very good and makes the more easy to visualize. If students are having a problem visualizing the theorem this site would be a great resource.

Ms. Martha,
I was one of those students who did not pick a name for one of my websites
(when we had to look up 5 a coupla weeks back.) My fifth site was
www.mathgoodies.com and is sandwiched betweenmy other 4 on your web site.
