Earlier this week I was catching up on some RSS feeds in Feedly when I came across this drawing from the patent application for the board game that became Monopoly. That drawing was the featured artifact of the day on the Today's Document website published by the U.S. National Archives. It's a resource that I frequently used when I taught U.S. History. Every morning Today's Document features a new image or document from the archives. The documents are usually accompanied by some additional research links and lesson plan resources. 

Applications for Education
When I was teaching U.S. History I used both of the resources on a regular basis. Sometimes I'd use, with modification, the lesson plans associated with the artifacts. Most of the time I just used the featured artifacts to spark little discussions about moments in history.
