Five instructional units on the metric system of weights and measures are provided in this document designed for use with bilingual (English and Spanish) students in postsecondary and adult vocational education programs. (This document, divided into Spanish and English versions, is designed to be used with three documents--CE 022 167, CE 022 168, and CE 022 169.) The unit titles are (1) measuring length and finding area, (2) measuring volume, (3) measuring time and finding speed and acceleration rates, (4) measuring mass and power, and (5) measuring temperature and energy. Each unit uses the common reference point approach to instruction and includes these elements: a statement of objectives, suggested activities for instructor and student, information sheets, assignment and job sheets, transparency masters, and a unit test with answer key.
