Matematicas Visuales
In MatematicasVisuales you will find visual expositions of mathematical concepts. MatematicasVisuales intends to complement the work initiated by artiludios, a site with games, puzzles and mathematical curiosities. Reading Miguel de Guzmán I found a demonstration of the line of Simpson and the Steiner Deltoid. It serves as an introduction to the geometry section.

What about free graphing and algebra on your mobile phone? XCalc is a free Java Applet which offers a graphing calculator for any mobile phone which runs Java (which is nearly all of them now!) Think about the possibilities for classes that do not yet have access to graphing calculators! While limited (it does not yet have a trace facility) it DOES offer 2d and 3d graphing which is quite fast and powerful. Well worth a play! Now, combine that with quite a useful algebraic workpad that allows you to define variables and formulas and evaluate these.

Commutative Rings and Fields
Different algebraic systems are used in linear algebra. The most important are commutative rings with identity and fields. Definition. A ring is a set R with two binary operations addition (denoted +) and multiplication (denoted

Authentic Assessment in Mathematics Home Page
The Geometry Forum Summer '94 Workshop at Swarthmore College, Swarthmore, PA. The goal of this project was to collect and organize available INTERNET resources on Authentic Mathematical Assessment applicable to Secondary Schools. What is it? Are there examples? Where can I find additional information?
Graphical Linear Algebra
So far we have not discussed categories in any depth. The reason for this is that I wanted to give you a feel for working with diagrams, for which we do not really need any deeper theory. I hope that I managed to convince you that diagrammatic reasoning is very intuitive: stretching, tightening and sliding along wires are all quite easy to visualise and think about. String diagrams are a user friendly notation, and the operations on them are also quite intuitive, at least if you ever played with Lego. These intuitive aspects are extremely important. Similarly, it is perfectly usual to do sophisticated calculations using natural numbers without knowing the ins and outs of the Peano axioms, the definition of semirings, or the maths of initial algebras.
