review 1: This book is about prime numbers and factoring using numbers up to 100. I really did not enjoy the illustrations in this book because each monster has a defining feature that relates to its number and I found a few monsters whose characteristics were not clear enough to tell the corresponding number. I think it would be a little difficult for young children to keep track of the corners of the monsters while counting. I did like how the author had visuals of factoring, using groups of dots to show multiplication.
review 2: This book was recommended to me by an English teacher; her 9-year-old son was fascinated by it. Each number is depicted by a monster; composite numbers have the accompanying factor tree on the left side, with a composite monster on the right.... more Prime numbers have more unique monsters that are not simply divided into smaller parts, like composite numbers that can be factored.This book could be used on several different levels, and in some cases, I wasn't sure how the monster (prime ones in particular) represented the number. (EX: 79) The book could be used with many different ages; much more complex explanations are in the back of the book. Teachers could simply show a page or two and have students off to the races! It's a different, colorful way to look at numbers.The NPR interview with the author is interesting, as well. less
