Some 500 trade books are reviewed and rated with a star system, and include indication of grade level (1-6) as well as indication whether they are single- or multiconcept. Some out-of-print titles are included because of their exceptional content. Entries are arranged by subject, e.g. early number concepts, number extension and connections, measurement, and geometry and spatial sense. Indexing is by author and title; a grade level index would have been useful. Published by the National Council of Teachers of Mathematics, 1906 Association Dr., Reston, VA 22091-1593.

Get ahead in pre-calculus Pre-calculus courses have become increasingly popular with 35 percent of students in the U.S. taking the course in middle or high school. Often, completion of such a course is a prerequisite for calculus and other upper level mathematics courses. Pre-Calculus For Dummies is an invaluable resource for students enrolled in pre-calculus courses. By presenting the essential topics in a clear and concise manner, the book helps students improve their understanding of pre-calculus and become prepared for upper level math courses. Provides fundamental information in an approachable manner Includes fresh example problems Practical explanations mirror today’s teaching methods Offers relevant cultural references Whether used as a classroom aid or as a refresher in preparation for an introductory calculus course, this book is one you’ll want to have on hand to perform your very best.
Offers an introduction to the principles of pre-calculus, covering such topics as functions, law of sines and cosines, identities, sequences, series, and binomials.
This book contains 15 chapters: (1) "Teaching Problem Solving"; (2) "Using Calculators and Computers in Elementary School Mathematics"; (3) "Organizing for Instruction"; (4) "Teaching Numeration of Whole Numbers"; (5) "Teaching Numeration of Common and Decimal Fractions"; (6) "Teaching Addition and Subtraction of Whole Numbers"; (7) "Teaching Multiplication and Division of Whole Numbers"; (8) "Teaching Addition and Subtraction of Common and Decimal Fractions"; (9) "Teaching Multiplication and Division of Common and Decimal Fractions"; (10) "Teaching Measurement"; (11) "Teaching Geometry"; (12) "Teaching Rates, Ratios, Proportions, and Percents"; (13) "Teaching Statistics and Probability"; (14) "Teaching Integers and Their Operations"; and (15) "Teaching Number Patterns and Theory." The two appendices include discussions on "Calculators and Computers" and "Mainstreaming--Can Individual Needs be Met"? The chapters in this book reflect the strands taught in the elementary school mathematics curriculum. Throughout each chapter are collections of problem sets that divide the chapter into sections. A number of these problems are similar to lessons that could be used with elementary school children. (PK)
LYTTON STRACHEY tells the following story. In intervals of relaxation from his art, the painter Degas used to try his hand at writing sonnets. One day, while so engaged, he found that his in spiration had run dry. In desperation he ran to his friend Mallarme, who was a poet. "My poem won't come out," he said, "and yet I'm full of excellent ideas. " "My dear Degas," Mallarme retorted, "poetry is not written with ideas, it is written with words. " If we seek an application of Mallarme's words to mathematics we find that we shall want to turn his paradox around. We are led to say that mathematics does not consist of formulas, it consists of ideas. What is platitudinous about this statement is that mathe matics, of course, consists of ideas. Who but the most unregenerate formalist, asserting that mathematics is a meaningless game played with symbols, would deny it? What is paradoxical about the state ment is that symbols and formulas dominate the mathematical page, and so one is naturally led to equate mathematics with its formulas.
