This PowerPoint is a good place to start when introducing new tribes. Images are given, encouraging students to make inferences about the location and environmental resources of each featured tribe. Following the images, several links are given leading to more information on each tribe. Lastly, there is a chart for each tribe giving a summary of the food, shelter, clothing, and location of each tribe.
I use this to introduce each tribe, and also as an available resource for students to use at home as a study guide.
Tribes featured are the Pawnee, Nez Perce, Hopi, Seminole, Inuit, and Kwakiutl.
