This competency-based secondary learning guide on improving individual, child, and family nutrition is part of a series that are adaptations of guides developed for adult consumer and homemaking education programs. The guides provide students with experiences that help them learn to do the following: make decisions; use creative approaches to solve problems; establish personal goals; communicate effectively; and apply management skills to situations faced as an individual, family member, student, and worker. Each learning guide includes the following sections: a general introduction and guidelines for using the material; a checklist for users for advance planning; introduction to the guide; specified competencies, with student outcomes/evaluations, definitions, key ideas, teacher strategies/methods, suggested student activities, sample assessments, and supplementary resources. The following competencies are addressed: define wellness; plan food choices to meet nutritional needs for individual, child, and family; assess mental health; and assess one's own state of physical fitness and identify needed improvement. Twenty-six supplements contain information and activity sheets on the following: health habits, wellness, food pyramid, nutrients, fast food, dietary goals, nutritional needs through the years, new food labels, personal strengths, self-esteem, assessing physical fitness, and taking a pulse.
