These four learning guides are self-instructional packets for four tasks identified as essential for performance on an entry-level job in mechanical drafting. Each guide is based on a terminal performance objective (task) and 2-4 enabling objectives. For each enabling objective, some or all of these materials may be presented: learning steps (outline of student activities) with necessary resources/materials cited, instruction sheet(s), and self-check with answer key. A performance test and/or a written test (with answer key) concludes each guide. Tasks covered in these guides include recognizing safe practices, constructing regular polygons and ellipses, and developing drawings for the pattern shop and the machine shop. (YLB)
