I have used Fakebook for a few years with my WHI kids to have them make comments between the gods. Fakebook lets students create comments and posts, upload pictures (or have them chosen from the Internet) and even add in video. If you watch my video above, it explains how to do all of this. For what it is worth there is also a FakeTweet and a FakeText.
The whole idea behind using Fakebook is having the kids summarize and synthesize what people might say to each other. So here is my assignment (which you could copy and tailor to your own needs). The kids really enjoy the assignment and the best part is that the Fakebook site creates a unique url and lets the kids add in their own password so they can work on the site on multiple occasions.
