These KQED interactive maps display the financial divide between four pairs of neighboring nations as measured by gross domestic product (GDP) per capita. They also show GDP per capita for all countries in the world. In the accompanying classroom activity, students learn how to calculate GDP per capita and then compare that for pairs of countries using data from the interactive maps. To get the most out of this activity, students should be comfortable with arithmetic with dollars and cents into the ten thousands. This resource is part of the Math at the Core: Middle School Collection.
