This book published in 1971 contains 72 pages of original problems in math and logic, featuring permutations, combinations, properties of numbers, algebra, solid and plane geometry, logic and probability. Although only high school math is needed to solve these problems, even accomplished mathematicians are likely to find some surprises here. Complete and ingenious solutions provided for all problems. 31 explanatory drawings.
Valuable and innovative classroom management strategies fill this indispensable guide to effective teaching. Explained in an easy-to-follow, concise format, each 2–3-page strategy includes a brief introductory scenario illustrating the technique's usefulness in the classroom, steps to implementing the strategy, a discussion of potential problems and suggestions for managing them, and viable ideas for adapting the techniques to fit different teaching situations.
This book is a continuation of the earlier volume and covers the years 1993 to 2001.
China has an outstanding record in the International Mathematical Olympiad, and the book contains the problems which were used to identify the team candidates and select the Chinese teams. The problems are meticulously constructed, many with distinctive flavour. They come in all levels of difficulty, from the relatively basic to the most challenging.
Arkadii Slinko, now at the University of Auckland, was one of the leading figures of the USSR Mathematical Olympiad Committee during the last years before democratisation. This book brings together the problems and solutions of the last four years of the All-Union Mathematics Olympiads. Not only are the problems and solutions highly expository but the book is worth reading alone for the fascinating history of mathematics competitions to be found in the introduction.
The great civilizations of Latin America were devastated after the arrival of the conquistadors and later the European colonizers, who created a society that was characterized by extreme differences between rich and poor - a legacy that continues to plague Latin America to a strong degree today. Although Latin American nations are no longer ruled by military dictatorships and have embraced democracy, social problems associated with the large income gap, such as poverty, landlessness and crime are pervasive.
