This book is the first in a series focusing on different topics in elementary school mathematics The author's premise is that "children must understand important core mathematical concepts . . . that are elaborated upon, expanded, refined, and deepened over time" (p. iv).
To help teachers improve their own understanding of the concepts, the book's introductory section contains background information about the ideas in the book.
