Actually that idea crossed my mind more than once in the past few months. There are currently a fair number of well written math texts on the web, mostly at their author's site. However, all of these are for advanced material.
My original concern was finding some good worksheets for my son. Failing to find any after a "fair" search of the 'net, except for publisher's advertisements and sample material - I constructed my own in WORD. Actually they look like the "real" thing (his quote), excepting for the absence of printed illustrations (but then I can draw well.)
After I produced a few of these, mostly for test-prep & review, it occured to me that I essentially had an electronic file for a 3rd grade math booklet - one that would normally go for $11.95 at the education resource section of one of the local book stores. And quite frankly, most of those review booklets tend to imitate each other. Nothing really exciting.
So how about an algebra 1 text for starts ?
Let me propose a challenge: we create several variants of a text book, work book, and supporting materials. Or maybe, several variants of diffrent topics. I think that would leave room to cover most people's philosophies. Each could do their own thing.
Certainly all of us have our favorites. So let's clone them.
What we need is a scaffolding of topics. In my opinion, the California Standards are the best point to start with. They can be build up or trimmed down, depending on what you think should be emphasized and how. I chose the Cal Standards since they're the simplest and most complete on the web. Canonical ? Now you may not agree with them*. Fine, but we all need a common reference point, and I can think of no other.
This leaves a lot of room for creativity.
So what do we think ?
Ok, maybe you don't want to do an algebra book. Then how about a geometry book or a 3rd grade math book ? The point is to produce something. Besides I KNOW a lot of you have already posted your little notes for all to see.
Let's pool our resources and create the first online algebra book. It would be a major challenge to the big four publishers.
