"Where are we ever going to use this?" Every high school math student has asked this question. Often teachers themselves aren't sure how to respond. One answer is that higher mathematics learned in high school will be essential to learning yet more at the college level. A more satisfactory answer calls for an awareness of how math is applied in many specific areas. Written primarily for teachers, this book presents hundreds of practical applications for mathematics--from baseball statistics to the theory of relativity--that can be understood by anyone with a knowledge of high school algebra, geometry and trigonometry.

Mathematicians and scientists have been closely tied to many famous disasters. The Challenger explosion, the failure of the Mars Orbiter, and the Kansas City Hyatt Regency walkway collapse all involved thinking errors. This book presents the ten things our future mathematicians and scientists must know to prevent these kinds of tragedies from occurring. Because science and mathematics instruction is often dominated by facts and calculation, children are rarely exposed to these important concepts. Over 50 stories are included that show children the strong connections between mathematics and science and the real world.

"A playful approach to some core ideas of mathematics, this book will help lay the foundation for understanding algebra and probability. Dr. O and his young associate Arya explore and discover ideas in ciphers, triangular numbers, primes and composites, probability, and a variety of fascinating number patterns. For a parent and curious child, or for a curious child alone, these mathematical investigations will invite re-reading and further exploration."--Back cover.

We are continually bombarded by charts, graphs, and quotes from various studies with the goal of influencing our opinions, health, or buying habits, yet we seldom know if we are being manipulated, deceived, and lied to by those presenting the data. Scammed by Statistics uses countless real examples to illustrate the good and evil of numbers and in the process, exposes the numerous techniques that are used to distort and misuse numbers. Readers will never again be able to read the news, watch TV, or read a magazine without a degree of healthy skepticism.

This book makes independent learning easy for both the student and the teacher (even those whose math skills are a little rusty). The fun activities in this book teach difficult concepts in areas such as statistics, probability, algebra, physics, trigonometry, astronomy, and calculus. Grades 3-9
