Review by Publisher's Weekly Review
This compact, innovative book counts to 100 using prime numbers represented as "monsters," each with identifying characteristics (two resembles a bee with two buggy eyes, and three is an angry-looking triangular creature). The book opens with explanations of multiplication, prime and composite numbers, and factor trees, then moves on to a list of numbers. Each prime number looks unique, while composite numbers are represented by scenes involving their prime monsters (eight is illustrated as three of the beelike twos, i.e., two times two times two. Readers may have difficulty deciphering the pictures, which come to resemble little works of abstract geometric art. But especially for creative learners, visualizing the roles each monster plays may lead to deeper number sense. Ages 4-8. (Mar.) (c) Copyright PWxyz, LLC. All rights reserved

Review by School Library Journal Review
Gr 4-8-This hybrid math/art book is both ambitious and imaginative. An introductory section explains the colored-dot configurations and factor trees for numbers 1 to 100, which appear on the verso of each spread. These factor trees are "all the way grown out" to the lowest common factors, or prime numbers. On the opposite page is a monster scene that represents the number. Schwartz has created a creature for each prime number: "Each monster has something about it that relates to its number, but sometimes you have to look hard (and count) to find it." Thus, the monster for 5 is a five-featured, five-pointed star, and the 13 monster sports a pink-and-white eye-patch with 13 segments. The illustration for 14 is a "7" monster eating a "2" monster. The "78" picture includes monsters representing 2, 3, and 13, the prime factors of that number. The pages are glossy black with flat, colorful abstractions. The author's claim, "The only thing you really need to know in order to enjoy this book is how to multiply whole numbers together, like 2 and 3," is an understatement; readers will need patience and an open, undaunted mind to deconstruct the monster scenes. This is a book for math lovers who want to have some fun. Challenge these students to create their own prime monsters and combinations. While the dot configurations and factor trees are less inventive, they provide a more concrete explanation of the math for the rest of us.-Barbara Auerbach, PS 217, Brooklyn, New York (c) Copyright 2010.
