Now that I've put some more thought into it, it seems to me that the classical method of teaching math really leaves out too much of the visualization of what it is a solver is trying to do, and that's also part of the problem people have with word problems.

One begins with arithmetic but there are pictures of apples or oranges or other things to convey a picture of what exactly is going on. And it's a language that describes relationships--I don't recall a math teacher I ever had that taught it as a language. Once I figured that part out, it became easier to translate word problems in English into Mathese.

I don't have a single resource recommendation, sorry. I wish I could remember the specific text I learned geometry with in high school decades ago--it was quite clear, beginning with definition and properties of a straight line, and progressed from there.

Incorporating algebra alongside Euclidean geometry would be something of a hybrid teaching method; what I had in mind was Euclidean line, then next linear equations because the mental picture would remain fresh.

Euclidean planes, then corresponding algebraic equations incorporating the plotting on a graph. While still in algebra, go to quadratics and explain those with Euclidean solids and conic sections.

I reeeealllly don't think there's a single text that teaches things that way, but I think you get the idea. Staying mentally in touch with the visual representation of the algebraic abstractions goes a long way towards information retention, I think.

Euclidean Geometry is great to start out with because the theorems and axioms tie in observation with operation from the get-go. The reasoning behind establishing the theorems and axioms is important to grasp even before you attempt all the abstract rules in algebra.

Having a grasp of what constitutes a valid theorem or axiom prepares a student to grasp how to discern from valid equivalents/operations from false equivalencies--which underscores how important proofs are AND checking your work before you hand it it AND understanding why an instructor insists that you "show your work".

It doesn't have to be plane geometry but if it was that'd be fine too. I'm imagining a workbook with example problems and then do one for yourself... Or some such thing. Obviously you also need some axioms and some basic theorems. That's why geometry is usually used. The axioms and theorems are not too abstract.

Yay, got the first post in a thread to display!! But this is an important thread and I'm looking at you, the "not strong on math" people. It's the reasoning that's important here even if you've never fancied yourself to be a mathematician when you grow up. You still need analytical thinking to go with everything else that you DO want to do.
