We have been watching a series of DVD's on the west from PBS.
The West from PBS. There are lesson plans on the website, as well.
Cartoon History of the United States
This is a very funny book. My oldest is really enjoying it. I'll try to get around posting some of his other books because they are just amazing! They are in comic book format. I know this aren't high enough literature for some, but I love books like this because they spark the interest in people and events. G will just be reading along..."Hey can we google this guy?"
