I would just add that UNICEF has a program called School in a Box. Essentially, you could be sitting under a shady tree and they will show up with School in a Box, which includes many of the elements that Diane just outlined. It's designed to let them be able to go anywhere and set up a school where there is a grouping of people brought together, if you don't have a classroom there.
