The activities in this volume of practical mathematics are intended for the intermediate grades. The manual contains three components which can be structured in different combinations according to different student needs. Built around a review of selected objectives in the mathematics basic curriculum, the material is intended to stimulate interest in both mathematics and the professional world. The first section of each component revolves around challenging and fun problems; the second section deals with practical aspects of math in everyday life; and the third component presents math problems similar to those students will encounter in contemporary life. The activities contain narratives, puzzles, games, and other activities of high interest and low readability. Each section is introduced by a statement of learning objectives, the cognitive and affective domains and levels concerned, materials, key words, and guidelines for implementation. Each section also contains an exercise that is applied to home and community, such as computing the price of an article that is being sold at a discount. The activities include exercises and evaluations based on the mathematical skill reviewed. The skills and life situations dealt with in this volume are public services; square roots; using fractions in marketing and distribution; and decimals, fractions, and percentages in connection with business and office jobs.
