Preface<br > INTEGRATED MATHEMATICS: COURSE II， Second Edition， is a thorough<br > revision of a textbook that has been a leader in presenting high school<br > mathematics in a contemporary， integrated manner. Over the last<br > decade， this integrated approach has undergone further changes and<br > refinements. Amsco s Second Edition reflects these developments.<br > The Amsco book parallels the integrated approach to the teaching of<br > high school mathematics that is being promoted by the National<br > Council of Teachers of Mathematics (NCTM) in its STANDARDS FOR<br > SCHOOL MATHEMATICS. Moreover， the Amsco book implements<br > many of the suggestions set forth in the NCTM Standards， which are<br > the acknowledged guidelines for achieving a higher level of excellence<br > in the study of mathematics.<br > In this new edition， which fully satisfies the requirements of the<br > revised New York State Syllabus:<br > ~ Problem solving has been expanded by (1) adding nonroutine prob-<br > lems for selected topics and to Chapter Reviews， and (2) providing， in the<br > Teacher s Manual， Bonus questions for each chapter.<br > ~ Integration of Geometry， Logic， Algebra， and other branches of<br >mathematics， for which the First Edition was well known， has been<br >broadened by the inclusion of new topics and the earlier introduction of<br >selected concepts.<br >~ Algebraic skills from Course I have been maintained， strengthened，<br >and expanded as a bridge to the requirements of Course III. Note that<br >many of these skills， newly highlighted in the revised Syllabus， already<br >appear in the First Edition of the AMSCO text.<br >~ Enrichment has been extended by (1) increasing the number of<br >challenging exercises， (2) introducing a variety of optional topics， and<br >(3) adding to the Teacher s Manual more thought-provoking aspects of<br >topics in the text， and supplementary material that reflects current<br >thinking in mathematics education.<br >~ Hands-on activities have been included in the Teacher s Manual to<br >promote understanding through discovery.<br > iii<br >
