In establishing the basic laws of the land and creating our three branches of government, the U.S. Constitution is among the most important documents ever written. But what exactly is a constitution? And why do nations need one in the first place? In this volume, readers consider what it might be like if there were no rules to follow in a schoolyard game—and why it’s important that countries have rules. 32 pages, full-color photographs, paperback, grades 4-6.
