This booklet on human relations attempts to convey to teachers the meaning and intent of "learning to live together." Separate sections deal with what teachers need to know about blacks, American Indians, Mexican-Americans, Puerto Ricans, the disadvantaged, Asian-Americans, Jews, and the many Caucasian ethnic groups. The focus in each race is on their history, social problems, differences within the race, and social differences due to past and present experiences, and in the case of the disadvantaged, on nutrition, environmental influences, and socioeconomic background.
