The purpose of this module is to teach the basic metric measures of length, area, volume, capacity, mass, and temperature. It introduces students to metric prefixes, abbreviations, and unit conversions with the system. Illustrative and optional material compares metric measures to our familiar American standard measures. The purposes are accomplished through the use of detailed explanations, experiments, charts, games, and manipulatives. After an introduction which points up the need for a uniform international measurement system, the student proceeds through a series of experiments and worksheets. Most problems are related in some way to a physical model or actual measurement device. (Author/MK)
