Yours, mine, and ours: Determining boundaries
http://www.nationalgeographic.com/xpeditions/lessons/13/g912/yoursmine.html
A lesson plan for grades 10–12 Social Studies
Consider the term “boundary.” Now apply it to Earth. Earth is crisscrossed and layered with a system of complex divisions. Beyond the familiar political boundaries of countries, states, provinces, cities, towns, and counties, there are legislative districts, school districts, police precincts, sewer or water districts, the property lines of residential subdivisions, and many more boundaries within which people live. Some boundaries are blurred, based largely on personal or group perceptions: ethnic neighborhoods (Little Italy, Chinatown) or larger perceptual regions (Tidewater, the Middle East).
In this lesson, students assume the roles of decision makers in a boundary dispute. They are asked to consider existing boundaries and other characteristics of an area to reach a consensus on whether an area should be divided or remain a single political entity.
