MathJax is used to create dynamic, correctly-displayed mathematics—no images!
This state-of-the-art method of representing mathematics is what makes the randomly-generated exercises and worksheets possible.PRACTICE

Every lesson has unlimited, randomly-generated online exercises that are *tightly linked*with the exposition, so you can check your understanding.

QUIZZES

Every lesson has unlimited, randomly-generated quiz/worksheet generation, with solutions. Students can print out practice sheets.
Teachers can give a different quiz to each class, or to every student!FREE

free of charge; the single ad at the top of each page doesn't show when you're reading the content; Adsense ads attempt to target things that are of interest to the user; Amazon purchases can support site; donations are gratefully acceptedRESOURCES

Where appropriate, students are taught how to use WolframAlpha.The geometry course includes instruction on GeoGebra.

OTHER

Information on the mathematical language is incorporated throughout the course, so students learn *how to read mathematics*while they're learning mathematics.

This 10-page pdf file will give you a sense of what this ‘math language’ stuff is all about, and also gives a sample of the author's writing style. (The whole book is here, if you're interested!)

Algebra Pinball shows you just how fast some students have been able to do the skill exercises! Just TRY to beat them!

FUN STUFF is included in each Algebra I lesson (right column) for breaks!

‘Fun Facts’ are scattered throughout the site, so you can ‘get to know’ the author.

JSXGraph is used to create dynamic graphics (like this triangle exploration).

The main Table of Contents includes SAT prep, a slide show to learn about the site, testimonials, and much more.

All these web sites are great.

Just as different students prefer different teachers,

one site may work better for you than another.

Take a look at all of them!

A site that is written by a single author
has the nice feature

that all the writing is ‘in the same voice’.

You get used to the way a person ‘talks’,

and this familiarity can be calming.

There is superb free online math technology available.

Emphasis should be moving away from ‘just calculating’,

because computers do it better than humans.

Students need to understand the beautiful IDEAS in math.

Students need to be exposed to the best available math tools,

and learn how to use them appropriately.
