Best free digital curriculum?

I have started a series of 10 workshops around the state of Oklahoma this week that focus on eRate as well as free sources of high quality digital curriculum. When it comes to free digital curriculum I don’t want to overwhelm people with too many choices (because certainly there are a huge number of options) but rather give them a sampling of some of the best. I am including web-based resources in all cases, with the exception of Google Earth. (I would put Google Earth in a category of “web-enabled software,” I think it is too powerful to leave out of this discussion.)

Are there other links you’d include in this top sampler of free digital curriculum? Do you know of sources for other engaging multimedia books like Roy: Tale of a Singing Zebra?

On this day..
