We have reviewed HTML before, but we're going to do some more of it once more. Most students will be involved with a large project dedicated to supporting our very special needs students. Those who choose not to be involved will be doing their own portfolios.
Our first step: learn the basics of HTML. Our "lessons" are at http://www.w3schools.com/html and will include everything up to, and including "iframes". Students should be able to write complete web pages using Notepad or some other simple text editor, mostly without notes once we're done.
The first 4 lessons should be done in Day 1, and then 1 or 2 lessons each day after that.
