by Johnny Ball
Of all the books about math that we have purchased or checked out of the library, this is our favorite. My son was already interested in math when we bought this, but I credit this book with convincing him that math is the coolest subject.
Every brightly-colored page of this book is packed with pictures and fascinating information on topics such as ancient number systems, infinity, prime numbers, and fractals. There is so much on each page, that it may seem a little overwhelming at first, but that is part of what it makes this book so great. You can come back to it again and again and learn something new each time.
The book is divided into four main chapters:
- Where do Numbers come from?
- Magic Numbers
- Shaping Up
- The World of Math
Some of the questions that Ball answers in the book include:
- Did Cavemen Count?
- How many molecules are in one glass of water?
- How do insects use prime timing to survive?
- Why are hexagons found so often in nature?
In addition to all the information, Ball includes many brain-teasers and activities you can try at home, such as making a tetrahedron out of an envelope and drawing your own maze.
This book is recommended for ages 8 and up, but it could be good for child that is slightly younger. I bought it for my son when he was 5, and my daughter, who is currently 5, enjoys looking at the pictures. I highly recommend this book to anyone who has a child that is interested in math or anyone looking for a little inspiration to help their child love math.
