Reviews

"Besides depicting the kids learning the metric system, the lively digital illustrations help readers visualize the metric measurements for length (or distance), weight, and volume. . . . Along the way, Adler explains how to convert a measurement from one system to the other and suggests practical, hands-on activities to help readers become more comfortable with the metric system. With few children’s books available on metric measurement, this useful resource will be an excellent addition to many library collections." —Booklist
