PBS Television has produced an incredible new series and resource for social studies teachers: WE SHALL REMAIN
From the PBS site: http://www.pbs.org/wgbh/amex/weshallremain/the_films/about
"At the heart of the project is a five-part television series that shows how Native peoples valiantly resisted expulsion from their lands and fought the extinction of their culture -- from the Wampanoags of New England in the 1600s who used their alliance with the English to weaken rival tribes, to the bold new leaders of the 1970s who harnessed the momentum of the civil rights movement to forge a pan-Indian identity. We Shall Remain represents an unprecedented collaboration between Native and non-Native filmmakers and involves Native advisors and scholars at all levels of the project."
The 5 episodes can be viewed online, and extensive teacher materials are available for each episode:
