This volume includes student manuals for four units in the Career Oriented Mathematics Program, which was developed to improve computational abilities and attitudes of secondary students by presenting the material in a job-relevant context. The units are titled: (1) Owning an Automobile and Driving as a Career, (2) Retail Sales, (3) Measurement, and (4) Area-Perimeter. The manuals are consumable, primarily consisting of worksheets which provide both mathematical problems and information needed for their solution (tax tables, maps, inventory records, etc.). The unit on area and perimeter presents problems using lattice point displays. Practice examinations are included. (SD)
