If you're interested in downloading a free unit study, this website offers a different one every 6 months. This time it's about the many First Ladies we've had in the United States. Very interesting information, and lots of it - the unit study is 81 pages long, with plenty of activities included. It appears to be adaptable to different ages too. Well worth a look!
