An attractive collection of simple games and exercises for improving perception in key curriculum areas, with appropriate grade levels indicated. The mathematics activities include magic squares, playing-card variations, number work, elementary geometry explorations (some highly imaginative), and a unit on metrics; only basic materials--pencil and paper, dice, clocks--are required. The exercises for sharpening verbal skills are also easy to introduce: homophones, homographs, magic spelling squares, rhymes, logic problems, and word puzzles. In addition, a smaller number of activities involving wind-action observation are suggested. Strictly for teachers and other adults working with groups of young children, this is a sizable assemblage of challenging problems suitable for upper elementary and junior high classrooms.
