Attention history teachers : The History Channel is offering a FREE set of DVDs from their upcoming (April 2010) new series "AMERICA The Story of US". Each school in the country can request a free DVD set if their principal fills out the information on this site.
This series will be amazing and I'm sure each school would benefit from having it in their collection.
Here is some more information about the upcoming series from History:
