http://www.historyforkids.org/learn/china/ is Kidpede’s beautiful site for upper elementary and middle school students. The unit on Ancient China is a series of one-to-two page, well-written overviews of Chinese environment (with maps), clothing, economy, science, literature, games, philosophy, food, people, art, and architecture. Each page includes hyper-linked key terms, as well as pictures and a bibliography of about five reviewed children’s books on the subject (with author, date, and summary, and linked to Amazon.com) to add to a classroom library.
