This mental health curriculum guide, intended for use with children in grades four through six, further develops the concepts and understandings introduced in the primary grades. The contents of the guide are presented in outline form and cover the family as a social unit, role arrangements in family life, and the construct of personality. For each content area and its sub-divisions fundamental concepts and understandings, teaching aids, and learning activities are suggested. The guide also supplies supplementary information--including further definitions, the process of human reproduction, and the psychology of puberty--which a teacher could incorporate into the lessons at a simplified level. Outcomes of this unit in mental health are given in terms of the student's understanding of interpersonal familial relationships, of increased responsibility for his own personal decisions and behaviors, and of his appreciation of the complex physical, emotional, and social changes one experiences in the process of growing and developing toward adulthood.
