An instructor's manual and student activity guide on masonry are provided in this set of prevocational education materials which focuses on the vocational area of trade and industry. (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 (six to fourteen days), activity goals, instructional objectives (fifteen), related vocational clusters, and activity implementation (description, materials needed, safety considerations, teacher preparation prior to class, during the class, follow-up activities, answer key(s) to instructional objectives 1, 2, 3, and 4, and duplication masters of student question and answer sheets). The student activity guide provides step-by-step instructions (narrative and illustrations) for completing each instructional objective (e.g., identify terms related to masonry, mix practice mortar, lay a course of bricks). At the end of each set of instructions is a student check point (evaluation activity). Occupational descriptions for a bricklayer supervisor, stonemason supervisor, bricklayer, and stonemason conclude the document. (JH)
