An instructor's manual and student activity guide on general clerical work related to the consumer market are provided in this set of prevocational education materials which focuses on the vocational area of office occupations. (This set of materials is one of ninety-two prevocational education sets arranged around a cluster of seven vocational offerings: agriculture, home economics, distributive education, health occupations, world of work, trade and industry, and office occupations.) The instructor's guide is organized into the following elements: title of activity, duration of activity (four to six days), activity goals, four instructional objectives, related vocational clusters and activity implementation (description, materials needed, safety considerations, teacher preparation prior to class, during the class, follow-up activities, answer keys to student check point activities, and masters for duplication). The student activity guide provides step-by-step instructions (narrative and illustrations) for completing each instructional objective. At the end of each set of instructions is a student check point (evaluation activity). Twelve occupational descriptions (e.g., order clerk, inventory clerk, invoice-control clerk, sales attendant, purchasing agent) conclude the document. (CT)
