about AARP Web Design 101 Workshop

I am teaching a workshop for AARP starting the first week of the new year. It is a Web Design 101 class for their print team.. I am super excited about this, as it poses a new challenge for me and requires me to speak for an entire day for weeks on end! anyone that knows me, knows I love to talk about web design.. so fill in the blanks

I will be creating a site to manage the student work and for managing my source files etc.

This is a call for any great tutorials or resources on teaching html, css, and anything particular of interest to someone starting out.

Thanks!
