Children's LiteratureIt's spring in Monster Town and the Math MonstersAddison, Split, Multiplex and Minawant to plant two gardens. They call on Aunt Two Lips at her garden shop and ask her to deliver two sets of the same number of seeds. But when they arrive, the piles do not look the same. Follow along as the Monsters figure out the best way to count the seeds and discover that two rows can look very different but still have the same number of seeds. Entertaining and amusing, this book is an excellent way to introduce children to the concept of number conservation, or how an object's number, quantity or length do not change even if that object is moved, rearranged or hidden. The book uses photographs from the Math Monsters public television series as well as simple, easy-to-read text. Multiple questions throughout the book actively engage the reader and related activities listed at the book's end give children and adults an opportunity to reinforce the book's concepts by putting them into practice. The Math Monsters public television series was developed in cooperation with the National Council of Teachers of Mathematics (NCTM). The "Math Monsters" series of books is designed to meet and support NCTM Standards for Pre-K-2 mathematics content and process instruction. 2004, Weekly Reader Early Learning Library, Ages 5 up.
