This book contains 105 articles dealing with games for use in the elementary or middle school mathematics classroom. All the articles originally appeared in the "Arithmetic Teacher" between 1956 and 1974. In this volume the papers are arranged in nine categories: (1) using games and puzzles, (2) whole numbers, (3) numeration, (4) integers, (5) rational numbers, (6) number theory and patterns, (7) geometry and measurement, (8) reasoning and logic, and (9) multipurpose games and puzzles. While some of the games are aimed at review or practice on basic skills others were designed with multiple objectives in mind. There is a great variety in the forms of the games; board games, crossword-type puzzles, paper and pencil games, manipulative puzzles for individual solution, and many others are included. Some of the games were developed by students; many others were designed by teachers. (SD)
