I created 5 lists and diigoed 5 sites per list. My favorite sites for each list that I found were:

For government: https://www.icivics.org/games

For geography: http://www.sheppardsoftware.com/Geography.htm

For American Revolution: http://teachingamericanhistory.org/static/neh/interactives/americanrevolution/

For Ancient Egypt: http://www.childrensuniversity.manchester.ac.uk/interactives/history/egypt/egyptianmap/

For Current Events: http://www.flocabulary.com/subjects/

I can't wait to see all the great sites everyone else found!
