I've added a new link, that one to my registry at DonorsChoose. On their general site, you can search for teachers and classrooms by any topic/area, and make donations online to fund their projects. I've got a list started. The Fast Food Nation one is at the middle school (now reorganized) where I did my student teaching. It's in a high-crime, poverty-and-drug area of East Oakland. They need this teacher and that lesson.
