The mathematics curriculum activities presented in this guide were developed as one component of a total career education demonstration project for Appalachian Maryland, and are intended for use as supplements to the total middle or junior high school curriculum. Introductory material lists career education concepts and outlines career and occupational development objectives. The body of the guide consists of sixteen mathematics units covering the following areas: whole numbers, numeral systems, fractions, decimals, ratios and proportions, percent, integers, graphing, plane and solid geometry, measurement, finding the perimeter, finding areas, computing volume, the metric system, story problems, and computing probability. Each unit relates career education activities to one or more concepts within the unit area. Career education activities are identified according to type of activity (e.g., student project, research, mathematical problems, discussion, resource materials). Materials required for many of the activities are appended. (SH)
