This guide and the accompanying student workbook (separate document) comprise the Adult Basic Education Level II (grades 4, 5, and 6) package on the metric system. An introductory section provides background information on adult basic daily living skills, a discussion of the design and use of the student workbook, and information on what the teacher needs to know about the metric system (six pages). Five instructional sections are included: Linear, area, mass, capacity, and temperature. Each section includes learning activities and additional comments (both of which relate to specified pages in the student workbook) and lists of materials needed. Appended are sources of material (complete addresses and ERIC document numbers, where possible) on adult education and/or the metric system, instructions for using the student test booklets, two student test booklets (forms 1 and 2), and answers to student tests (forms 1 and 2).
