"While our world has many different places with different governments and economies, it is still vastly interwoven, through the global community. The United States has the world's largest economy. It is a massive importer and exporter, creating a constant wave of commerce. Canada's largest exports are mineral fuels, vehicles, precious metals, wood, and computers. Your budding economists will analyze how the advances in science, technology, and economics in the United States and Canada impact the larger global community. Readers will survey how past and present technologies are tied into each area's natural resources and factors of production. The extent to which United States and Canada rely on and contribute to the economies of other regions is explained. Graphic organizers and vivid photographs support the analytical narrative." -- amazon.com
