app

by Theoni Pappas & Dale Lindley

Kick start your brain with MATHCHALLENGES. 99 challenges that will exercise those gray cells. Whether it's a computation problem, a thought challenge, problems involving advanced equations or just challenges that use plain old logic, you'll have to resort to mathematical thinking. Remember mathematics is an active sport. A pencil, paper and perhaps a calculator are your tools. The challenges cover a range of math problems, which may both challenge and amuse you. Sometimes math skills will help you solve them, other times you may rely only on logic.

MATHCHALLENGES is designed so that you can tackle only one mathematical challenge in a twenty-four hour period. During that time, if you get stuck, you can ask for a hint. Or, if you are frustrated, you can always look at the solution, but you cannot go to the next challenge until a day has passed. Why? Because for some challenges our minds may need time to process the information and seek out that 'aha' moment. Some math challenges need time to percolate in our minds. So to remove the temptation of rushing to know the answer, the 24 hour rule lets us mull over the problem, and even, perhaps, come up with alternate ways to solve it. A hint can be accessed for a challenge in case you need a boost, and when you do check your answer, an in-depth solution is given which may afford new insights.

Problem solving fuels imagination and creativity. These 99 challenges will stimulate your brain, challenge your wits and increase your confidence. Solving or understanding the solutions will both increase your confidence and understanding of math, and with each solution you will experience a sense of accomplishment. The challenges that you don't solve will perhaps provide new insights on how to approach various problems. By the end of these 99 challenges you will have enhanced your mathematical tool kit.

In each story, properties and characteristics of math ideas are uncovered and explained through the dialogues and actions of its math characters. Readers forget they're learning as they get caught up in the characters' private lives, secrets, and interactions.

"Numbers & Other Math Ideas Come Alive by Theoni Pappas is a fun look at numbers and shapes and their properties. Pappas personifies numbers and shapes, modeling their properties as they interact and explaining their point of view. Each chaper cover a different mathematical idea from the viewpoint of numbers or shapes, explaining concepts though experiences of characters. ... This book covers math concpets that are appropriate for both middle school and high school students. ... a fun and creative way to begin a discussion about new mathematical concepts and to pique the interests of students. A possible extention of this book is to have students write their own stories about mathematical concepts. ...This book is a great way to start that process with young mathematicians in our classrooms."

"The Joy of Mathematics presents the world of mathematics to readers in a fresh, original way. For any reader, mathematician or not easily readable by all readily usable for enrichment I highly recommend it."

-The Mathematics Teacher

"Rarely does one come across books on mathematics with such breath, beauty, and insight. Pappas' books always contain fascinating and valuable information-not only for curious students and laypeople-but also for the seasoned researcher. The eclectic Pappas is both a mathematician and a poet, and with the cold logic of the one and the inspired vision of the other, she selects topics sure to stimulate readers' imagination and sense of wonder at the incredible vastness of our mathematics universe."

-Clifford A. Pickover,

author of Computers & the Imagination
