This career exploration instructional unit is one of several resulting from the rural southwestern Colorado CEPAC Project (Career Education Process of Attitude Change). Using the construction of a dog house to give meaning to measurement skills and area computation, the unit includes (1) five behavioral objectives, the teaching strategy, the specific basic skills being taught, and the evaluation method and (2) five activities for students to perform in planning the dog house and ordering the necessary materials. Because this unit is part of a career education laboratory program, a two-page overview of the goals, objectives, personnel organization, target group (fifth and sixth graders), materials, budget, timeline, and evaluation relative to the whole program is included. An occupational brief chart for students to use in summarizing the key factors regarding an occupation is appended. (EM)
