Federal Resources for Educational Excellence (FREE) is among the most popular K-12 web sites maintained by the U.S. Department of Education because it makes it easy to find teaching and learning resources from the federal government. These resources are made available by 60-plus government agencies, from the Abraham Lincoln Bicentennial Commission to the U.S. Mint. The materials include animations, primary documents, photos, and videos. A detailed subject map allows searching by curriculum area, such as language arts, math, and U.S. history. Access is also provided through an alphabetical listing of specific topics.
