An older site, but one which is worth highlighting!
Fakebook (http://www.classtools.net/fb/home/page) is a face-book-like site where teachers can create FAKE profiles for fictional or historical characters for study purposes. There are some SUPERB profiles and exchanges already on the site (though they are hard to find!) but teachers can add their own. It makes for a unique way to explore some historical events in a way that today’s pupils will find engaging and easy to understand, it can also be used to really get under the skin of fictional characters too! Another use may be as a tool for esafety discussions. Well worth taking a look at.
One of my favourite Fakebook Characters is Josef Stalin who’s “wall” can be found at http://www.classtools.net/fb/30/IlZ3WR
