This metric supplement is intended as a guide to aid the industrial arts teacher in incorporating metrics in the classroom. A list of student objectives for measurement skills is followed by an overview of the history of measurement, an argument for change to the metric system in the United States, and a discussion of metric basics (common terms). The next section contains both activities for introducing the metric system, which are written to give students experience using the basic units of metric measure, and pre- and post tests. In the following section the use of metric measurement is covered for these specific areas of industrial arts: drafting, metalworking, woodworking, graphic arts, power/transportation, and electricity/electronics. Each section includes a discussion of where and how changes needed to convert to the metric system should occur as well as suggestions for facilitating the use of metric measurement, sample activities and/or sample problems. A section on converting tools and equipment also contains a list of suggested metric materials for each industrial arts department. A listing of available resources cites sources for books, pamphlets, films/film-strips/slides, kits, posters, charts, periodicals, and supplies and equipment. (YLB)
