D2.Geo.2.9-12 Maps, regions, and political and economic dynamics
Use maps, satellite images, photographs, and other representations to explain relationships between the locations of places and regions and their political, cultural, and economic dynamics.
Why water teaches this standard well
Most major cities sit on rivers, harbors, or aquifers, and maps make that pattern impossible to miss. Students can use maps and imagery to explain how access to water shaped where economic and political power concentrated, from river ports to irrigated valleys to basins whose boundaries cross state and national borders.
Materials tagged with this code are written to the full standard , and each carries a written note explaining the alignment. See how we review materials.
