Parents need to know that this site is the U.S. Government Printing Office's educational online outreach for grades K to 12. The nonpartisan, text-heavy site provides tutorials and games on all branches of U.S. government, history, states, and symbols. It's informative, but amusing enough that kids will actually enjoy learning things. Parents and teachers may have to help younger kids sift through the lengthy information and read them only the most relevant parts.
Educational value:Kids can find almost anything about U.S. government or a link to another appropriate site.
