This workbook and the accompanying instructor's guide, three audio tape cassettes, and script for the audio tape comprise the Adult Basic Education Level I (grade 1.5) package on the metric system. The workbook's six sections follow a problem solving approach and present measurement activities similar to those involved in daily activities (i.e., preparing foods and reading temperatures). The six sections correspond to the six sections in the instructor's guide and to the audio tape. Section titles are Linear Measurement, Measurement of Weight, Review of Linear and Weight Measurement, Measurement of Capacity, Measurement of Temperature, and Final Review. Supplementary diagrams and charts are included. (SH)
