How it works: how math works (How It Works)

This is a great math tool that I have sitting on my shelf and it has helped my kids do wonderful in math. I would additionally like to share this site http://thecyberprofessor.com/ which gave me the insight into know mathematical sciences as well.

This is simply the best math "activity" book out there! Well worth every dollar! Kids need help with many activities, but it is well worth the parent's time. The activities are not only educational but really FUN and engaging.

As a writer of educational materials, I have dozens of books like this on my reference shelf. Each has a different advantage, but HOW MATH WORKS is the best overall. It is full of fascinating information, easy-to-do experiments (yes, experiments!), and the clearest explanations of complex concepts I have seen. The full color layout is clean and appealing. The organizational features mentioned in other reviews are excellent. Highly recommended for teachers, parents, and others who work with students in grades 3-5.

A great resource for teaching math to kids from the very young to upper middle school. This wonderfully illustrated book covers everything from logic to probability and stats, with a little bit of Trig & Algebra thrown in for good measure. Each subject is covered to a reasonable depth in brief, simple language. There are oodles of 'feast-for-the-eyes' graphics, games, biography bits, obscure math facts, experiments, try-its, and tricks. The emphasis is on 'learning by doing' and makes good on the author's promise to "Share the Wonders of Mathematics"

This colorful, fun book is a far-ranging, nicely-illustrated exploration of the world of mathematics. It has sections on algebra, probability, statistics, calculation, geometry, topology, and more. Each pair of facing pages discusses a mathematical concept and its history. Most pages offer an amusing puzzle in which the concept plays a role along with a thing you can make or do that involves the concept (how to make a set of ``Napier's bones'' to help in multiplication, how a topologist can take his vest off without removing the jacket worn over it, a card-file/knitting needle database machine). A child who spends time with this book will learn to see math for the fun game it is.
