Richard Evan SchwartzRecensioni

Don't let the title or art fool you! This is a book EVERYONE should read. The provides what infinity really looks like. As a math minor, I thought I had a grip on what infinity is until I read this book. For young readers, they probably wont be able go through the whole book (Which is pointed out in the beginning).

The book brings the reader on an adventure over unimaginably large numbers. It has a few combinatoric problems and at the end it describes a notation for hyperoperations with base 10 such that a number x enclosed in an n-gon is 10[n]x, which is really nice.½

The book explores increasingly large numbers in a visually stunning way. I gave the book a five star rating because it makes the concepts of these large numbers more graspable and accessible to the average middle school student.

Coolest math book ever.

Prime numbers, factor trees, monsters? The boy devoured this over two days with both mama and papa.

This books talks about counting, prime numbers and introduces different shapes students will have to learn. This is a great book, for children to get more information on certain math concepts. I would use this is book for 2nd to 4th grades. This can be another outlet for children understanding math.

I was really disappointed with this book. The number 1 was sad, the monsters were overly complicated and did not elegantly explain their value, and the combinations of prime monsters were confusing (either not well done or way-too-overly clever topologically) and did not elegantly explain anything otherwise mathematical. The best part, although still not that well done, was the work done with dots on the left hand pages. The way the dots were colored and arranged often - but not always - demonstrated revealing characteristics of multiplication. I've seen people positively review this book, and say that it worked with their kids, but for me it was not intuitive½

The author has written a wonderfully illustrated book about the first 100 numbers and their characters (prime monsters). All you need to know is how to multiply whole numbers together (like 2 and 3), and this book will put you well on your way to understanding factor trees, primes and composites, and how to find prime numbers. With imaginative monsters and colorful drawings, this would be a great book for homeschoolers and educators to have on hand to make factoring not-so-scary. (except for those weird-looking, colorful monsters, that is!)

Monsters representing the prime numbers dance in this illustrated book about the factorization of the integers from 1 to 100. Schwartz handles this unlikely topic well with brightly colored, geometric digital illustrations and a minimum of text. A section introducing the concepts of prime and composite numbers and prime factorization opens the volume, and it closes with a demonstration of the Sieve of Eratosthenes and the proof of the inexhaustibility of primes. The black background of the pages sets off the illustrations well, but makes the white text difficult on the eyes to read. Younger readers will enjoy paging through the text looking at the illustrations, but it is probably best suited for the classroom library of math teachers who are teaching this topic.½
