The student workbook is derived from "An Ethnological Report on Cheyenne and Arapaho: Aboriginal Occupation," by Zachary Gussow and "Northern Snows to Southern Summers--An Arapaho Odyssey," by Bob Spoonhunter. The first section discusses the Arapaho origins by recounting many different legends that explain how they arrived on the Great Plains. The story is accompanied by a word list, maps, and a learning activity. The next section covers the Arapaho economy which was mainly built around the buffalo. A list of buffalo uses among the Arapaho, art activities, and a 12-item test are provided for this section. Arapaho social organization is described in terms of the band which was essentially camp groups of relatives having a name and functioning as a political, social, and economic unit; societies, which were subdivisions of a band that carried out important military, economic, and ceremonial activities; and government or policy making activities. The section contains a list of words to define, discussion questions, and suggested supplemental reading materials. The last section deals with the Arapaho area of occupation on the Great Plains and contains a map of the historic Arapaho territory in 1851 and an 8-item quiz on the section. (AH)
