This core curriculum contains five units for use in teaching metrics to vocational students. Included in the first unit are a series of learning activities to familiarize students with the terminology of metrics, including the prefixes and their values. Measures of distance and speed are covered. Discussed next are measures of volume used with solids and liquids. Terminology of metric weight and mass measurement as well as conversion to the metric system from the American standard system are addressed in a series of activities. The final unit consists of exercises to enable students to relate temperature scales to one another. Included in each unit are a terminal objective, specific objectives, suggested activities, a listing of instructional materials provided, references, information sheets, student handouts, unit tests, and test answers.
