I agree with rsisks in that teach them to plan properly.

Better than actually HOW to do it, is structure and basic etiquette. It really makes me...frustrated, when I see a website with a cluttered home page, or a website that has complex navigation. Teach them to plan, structure, and to lay things out

As for actual code, I started making websites just recently. And a basic understanding of HTML really helped before I went to DreamWeaver/CSS, simply because I could understand what was going on. So I would recommend teaching this, and developing an understanding.

From there, I would recommend introducing a Development Platform that OScubed talked about. That way they have a wide scope of knowledge on the subject.
