Designed to meet the job-related metric measurement needs of students interested in food distribution, this instructional package is one of five for the marketing and distribution cluster, part of a set of 55 packages for metric instruction in different occupations. The package is intended for students who already know the occupational terminology, measurement terms, and tools currently in use. Each of the five units in this instructional package contains performance objectives, learning activities, and supporting information in the form of text, exercises, and tables. In addition, suggested teaching techniques are included. At the back of the package are objective-based evaluation items, a page of answers to the exercises and tests, a list of metric materials needed for the activities, references, and a list of suppliers. The material is designed to accommodate a variety of individual teaching and learning styles, e.g., independent study, small group, or whole-class activity. Exercises are intended to facilitate experiences with measurement instruments, tools, and devices used in this occupation and job-related tasks of estimating and measuring. Unit I, a general introduction to the metric system of measurement, provides informal, hands-on experiences for the students. This unit enables students to become familiar with the basic metric units, their symbols, and measurement instruments; and to develop a set of mental references for metric values. The metric system of notation also is explained. Unit 2 provides the metric terms which are used in this occupation and gives experience with occupational measurement tasks. Unit 3 focuses on job-related metric equivalents and their relationships. Unit 4 provides experience with recognizing and using metric instruments and tools in occupational measurement tasks. It also provides experience in comparing metric and customary measurement instruments. Unit 5 is designed to give students practice in converting customary and metric measurements, a skill considered useful during the transition to metric in each occupation. (HD)
