Arts; Crafts Across the U.S.A. The United States is one of the largest countries on Earth. It is a diverse and fascinating land. Each state within the United States is unique and holds treasures within it that are particular to it alone. The histories, cultures and people of each state are varied, too. To give students an insight to that diversity and richness, classroom teachers in every state in nearly every 4th, 5th or 6th grade are asked to teach about the U.S. This book aids in that teaching process.
