The 18 lessons in this unit of study are intended to promote an awareness of the contribution of the American Indian to the development of Oklahoma and to preserve the culture and heritage of the American Indians of the state. Each lesson includes a concept (one-sentence statement of the main idea), background information, learning activities (including an activity that personalizes the lesson), true/false or multiple choice test, and resources for further study. "Americans have taken on many aspects of Indian culture" is the concept of a lesson with background information on Indian contributions to American food, medications, roadways, recreation, language, and philosophy. The four suggested learning activities involve researching ethnic background, checking word origins, reading Indian legends associated with corn and other common foods, and identifying major highways that once were Indian trails. The personalization activity challenges the student to write a credo comparable to the Indian philosophy of "I respect my brother's wisdom." In addition to specific information about the Five Civilized Tribes, the lessons cover tribal legends, religion, cultural assimilation, tribal management, treaties, bilingual education, the revival of ancient crafts, traditional foods, folk medicine, and ceremonies.
