As part of a 3-year comprehensive interdisciplinary program developed by a group of educators from Hackensack High School, New Jersey, this teaching guide for a Grade 10 mathematics unit is designed as a year long study of measurement in preparation for further technical study in Grades 11 and 12. Daily lesson plans for the four sophomore units stress basic concepts and applications of mathematical measurement. Students construct models of ductwork, geometric solids, densities of metals, and paper box fabrication which promote group and individual participation in developing necessary concrete mathematical skills. The program incorporates the use of community resources for field trips and presentations, and includes line diagrams, quizzes, student worksheets, and activity lists. Introductory rationales precede each outlined unit. This volume is planned for use with four others, available as VT 015 228-VT 015 231 in this issue. (AG)
