Math Wars: A Guide for Parents and Teachers

Carmen Latterell

Praeger Publishers | 2004 | PDF | 200 páginas | PDF | 1,1 Mb


This book is written for parents and other interested parties so that they can understand the great debate taking place in many states in this country about how to teach basic math. The debate centers around the standards written by the National Council of Teachers of Mathematics (NCTM), which call for a radically different approach to mathematics education. Because the issues are so heated between the NCTM-oriented curricula and traditional curricula (the curricula that NCTM-oriented replaced), the term Math Wars was coined to describe them.
Parents are concerned about their children's math learning. Teachers are concerned about math teaching. When parents see what children are bringing home under the new curriculum, it is clear that their children are not working on the same mathematics that parents remember from the time when they were in school. But, the problem goes beyond grades K-12. Post-secondary mathematics courses are the fear of many students. The standards created by the NCTM do not necessarily prepare students for success, either on SATs or in college.
Besides lack of knowledge about mathematics education, many parents have an additional problem in that they feel they lack knowledge in mathematics itself. This is very intimidating; thus it is difficult for parents to do anything about the confusing state of mathematics education. This book provides some answers.

Flatland is a unique, delightful satire that has charmed readers for over a century. Published in 1884 by the English clergyman and headmaster Edwin A. Abbott, it is the fanciful tale of A. Square, a two-dimensional being who is whisked away by a mysterious visitor to The Land of Three Dimensions, an experience that forever alters his worldview.
Like the original, Ian Stewart’s commentary takes readers on a strange and wonderful journey. With clarity and wit, Stewart illuminates Abbott’s numerous Victorian references and touches on such diverse topics as ancient Babylon, Karl Marx, Mary Shelley’s Frankenstein, Mt. Everest, H.G. Wells, and phrenology. The Annotated Flatland makes fascinating connections between Flatland and Abbott’s era, resulting in a classic to rival Abbott’s own, and a book that will inspire and delight curious readers for generations to come.

Precalculus Enhanced with Graphing Utilities

Michael Sullivan
(6.ª Edição)

Pearson | 2012 | 1152 páginas | PDF | 36,9 MB

Michael Sullivan’s time-tested approach focuses students on the fundamental skills they need for the course:preparing for class, practicing with homework, and reviewing the concepts. The Enhanced with Graphing Utilities Serieshas evolved to meet today’s course needs by integrating the usage of graphing calculator, active-learning, and technology in new ways to help students be successful in their course, as well as in their future endeavors.

In the Sixth Edition, new worksheets in MyMathLab—developed from the authors’ experience in the classroom—provide mixed review for students who having trouble reconciling various topics, and also give students an opportunity to show their work. The “Are You Prepared?” section openers focus on students mastering the prerequisite material before beginning a new topic, and for the first time, those exercises are assignable in MyMathLab. Concept and Vocabulary exercises are also now assignable in MyMathLab as reading quizzes.
