Teacher Resources

This page is the handiwork of Fred Koch, a former member of our math department. Fred reviewed hundreds of internet math sites and selected those he considerd best.



Abstract Algebra On Line: This site contains many of the definitions and theorems from the area of mathematics called abstract algebra. It is intended for undergraduate students

Famous Curves Index: A great site for the Alg II or Pre-calc course

Math software: Assorted math software.

Interactive Diagnostic Tests: A series of three tests for algebra: beginning, intermediate and advanced. The advanced includes exponential and logarithmic equations. Answers are supplied.Well done.

Problem Solving: An extensive program for teaching word problem solving. Seemed very good. Well worth looking at.

WebEq: This is a technical site. You can download a free and very powerful equation editor that will also create visuals for you. It is located in the U. of Minnesota Geometry Center. From the home page, you will find the WebEq subpage. This is well worth the time to look for.


Geometry problem of the week: Solve this week's problem. Explore the archives for other challenges.

Euclid's Elements: This site contains the 13 books of Euclid's Elements. The value here is that every diagram associated with a theorem, is self-animating. One can see the diagram move in a variety of ways, always maintaining the conditions of the theorem. This is so fascinating that I spent far too much time here, browsing, and wishing that I were teaching geometry again. (This is a great place to send students to see what Euclid is all about.)

Geometry Junkyard: This is a collection of the odd but fascinating bits and pieces of very interesting geometry that doesn't really fit into any more standard category. I spent so much time here, totally interested.

Connections +: A very good site to explore. Find the subheading Math and click. You'll find the Geometry Junkyard there, also. As I went back and looked again I found more of interest. Particularly interesting were the sites devoted to polyhedra and polytopes. Some sites have lesson plans associated with them. This is a treasure trove of cool stuff in geometry

Famous Curves Index: There are many famous curves that I have never seen before, just heard of. While this is not strictly a geometry site, it is worth a look. What a playground. With Javascript then many of the curves become interactive. Ie. The Lissajous curves.

NonEuclid: A very interesting, interactive site exploring the math and the understanding of Non-Euclidean geometry using straight edge and compass constructions from the point of view of the Riemann model. Good way to go. Perfect for the better student.

MSDOS Software Collection for Geometry: A comprehensive collection of software (shareware, freeware, and commercial) to be used in the teaching of geometry. This is different from the collection in the Geometry Center website.


Famous Curves Index: Many famous curves that I saw for the first tiime. With Javascript, many become interactive, ie. Lissajous curves.

MtL-Trigonometry: A complete course in Trig, interactive via java applets. Parts are still under construction. Very nice otherwise.This could be used effectively as a supplement to the course being taught.


Writing Assignments in Calculus: A very clever and innovative way to get students to write a paper using mathematics. I was delighted to see this site. Several of our writing aids have a math background.

Famous Curves Index Famous curves: many I saw for the first time. With Javascript, many become interactive, ie. Lissajous curves.

TI Calculators. An interactive page for the use of the TI calculators: The first is the home page. And the second is specifically for the educational uses for a variety of TI Calculators.

The Integrator: This seems to be a good, interactive integral calculator. It is perhaps not much more than a very complete sourcebook of integrals. Needs some exploration to see just how extensive it is.

MATLAB to C++ compiler: Could be very useful to someone who knows C++.

AP Calculus: This is an extensive site devoted to preparing for the Calculus AP Test. It lists two AP Calculus Problems of the Week, The site includes links to previous problems of the week, their solution, and other items of interest to AP Calculus teachers and students. There are extensive tutorials. Very interactive.

calculus@internet: Four internet sites (more coming) all devoted to aspects of calculus. And interactive graphing site, with color available. Easy to work and gets good results.

Interactive Tutorial on Parametric Equations: This is a clever and very clear presentation.

Catalog of Software: A Catalog of software, (freeware, shareware, and commercial). A comprehensive list of programs available.

University of Arizona freeware programs: A comprehensive list of the usually excellent freeware programs available from the U. of A. They include a wide variety of topics.

Connected Curriculum Project: An Interactive and Interdisciplinary Program from the U. of Montana. This seems to be a rather complete program although parts of it seem to be under construction. What I saw was interesting.

University Calculus Sites: A generic list of mainly University sites involved in the teaching of calculus. Many of them are interactive.

Calculus Tutorial. From the Univ. of Akron: another calculus tutorial. Somewhat academic. Slow.

Differential Equations: An extensive diff. eq. Site. Very interactive.


Fractal Pictures: Serves as a resource for fractral images that show the concepts of chaos theory(geared to K-12).

The Fractal Microscope: Provides information of basic fracrtals, why they should be discussed, their purpose in the real world.

Great Fractal Site I: (Great fractal pictures.Printable.)(This is included below. Great wallpaper.)Arts: Visual Arts: Computer Generated: Fractals

Great Fractal Site II: (This site is so full of beautiful fractals, all downloadable, that after a while I simply ran out of time. I may paper the wall behind the computer with these print-outs.)

Great Fractal Site III: An exceptionally interesting site. Not only does the author give the mathematics and the formulae for computing many fractals, but he describes the processes. Then gives a gallery of his art work. Some of which is quite lovely. Well worth a visit.
