Product Description


Algebra Unplugged is unlike any other mathematics text about algebra. Through the use of creative analogies, the authors explain the areas that are often stumbling blocks for students. -- Mathematics Teaching in the Middle School

An excellent and enjoyable book. Worth having several copies around to loan to students. -- The American Mathematical Monthly

It's a remarkable little book by Kenn Amdahl, a poet and former math-phobe and Jim Loats, a math professor. Be advised that Algebra Unplugged does not take the approach that your high school math teacher and textbook took. It certainly answers some basic questions differently. Amdahl and Loats cover pretty much all the topics of first-year algebra and a great deal of earlier math that many kids don't really have a grip on. And they do it all in just 258 pages of remarkably readable and often hilarious text.

Both of my daughters read the book. One, a true math-phobe probably managed to pass algebra in ninth grade as much because of this little book as because of her teacher. My other daughter profited as well, though she's a math lover. Bruce M. Smith, managing editor. -- The Phi Delta Kappan, Feb 1998

Sometimes, despite endless explanations by teachers and dozens of homework assignments, students don't always grasp algebra. Some ask for help, others turn to books, hoping that one will explain things in language they can understand. This may be the book they are looking for. Explanations are short, humorous, and non technical. The authors convinced this reviewer that there is value in sneaking up on a potentially intimidating subject in this way, although I was not so sure at the beginning. -- Appraisal-Science Books for Young Adults

The book contains no exercises. Instead, it simply explains the concepts, vocabulary and strategies of algebra in understandable terms. -- Zentralblatt fuer Didaktic der Mathematik

The innovative author of There Are No Electrons asked math professor Jim Loats to teach him algebra. The result is this wonderful book which explains the basic concepts, vocabulary and strategies of algebra. No exercises, just clear writing, humor and information. -- The Genius Tribe

The volume's easy pace and the use of a game as a metaphor probably will appeal to the casual learner. The book's gentle, conversational, gamelike approach may be sufficient to reach the 'unreachable.' -- Science Books and Films

Product Description

Explains the concepts, strategies and vocabulary of algebra for people who like to understand concepts before they tackle problems. No exercises to complete. This is a book to read the weekend before you start your algebra course, or if you need to refresh your understanding before some test, or if you're struggling in class because you just don't understand what in the heck is going on. Easy reading, conversational style, some mild humor. Homeschoolers love this book. One of only 4 algebra books recommended by Encyclopedia Britannica Online.

4.0 out of 5 stars Great Math book Aug. 20 2002
Best of all the authors explain what it is you're doing when you do algebra. Why doesn't it make sense in the real world? Because it's a game. The conventions may seem arbitrary but the rules are not. The authors multiply things like tenors and pigs and divide them by all kinds of non-mathematical things in order to illustrate the logic of mathematical thinking. They also show that people are thinking algebraically even when they don't know they're doing so. This is a great book if you took algebra a long time ago and are not sure you remember the differences between the various mathematical disciplines. It's also good if you are the type who wants everything explained to you in math, rather than taking it on faith. It won't replace the standard textbook, but it will show you how to use it.

4.0 out of 5 stars Good to get the point across, but silly! June 14 2014
Format:Paperback|Verified Purchase
This book sure helped us as homeschoolers to understand the principles, and they use lots of 'humor' to help keep it interesting, and lots of examples. But it's actually quite silly sometimes which got tiresome. I very much recommend it if you can overlook that. They made it possible to understand the "real algebra book" as they put it.

Kenn Amdahl has succeeded in making algebra look like a game and maybe he is right.
I recommend this book to anybody who has the slightest interest in the subject. It reads almost like listening to your mathematically inclined buddy exchanging a few words on mathematics over a beer; that's what I felt, two buddies getting together and just shooting breeze over mathematics.
It certainly made me conscious of paying more attention to VOCABULARY and CONCEPTS and less on manipulation.
You won't regret the time you spent on this book nor the money!
