Technique will follow
I've started to think that perhaps the right, responsible way to approach the teaching of mathematics is to willfully place skills and techniques, always, in a position subservient to concepts.
What is Algebra? I've become convinced that it is not the manipulation of variables-- the "arithmetic with unknowns" that I've previously described-- but rather, that Algebra (in despite of it's etymolgical roots?) is the *idea* of the variable, the All-Number, the dice in hand. If this is well understood, in all it's richness, the solutions to equations are trivial practice-- technique and form that flow easily, just as the artist, with a rich understanding of light and shadow, creates the image fluidly.
Add to this a rich and powerful sense of proportion, built upon the scaffold that is born into us, in the way that intuition understands logrithms better than linear systems, and you're a long way towards the entirety of the typical high school math curriculum.

Ah, now you and I have found the same thing to be true. Technique should be subservient to concept!
We taught a heck of a lot fewer techniques in this last class at North Park, and focused a lot more tightly on concept. And there are some kids looking like they are fighting!
