Twenty teacher-developed elementary and secondary instructional activities on geography-related topics are available in a single activity, loose-leaf format as an on-going series. Simulations, role playing, mapping, group discussion, experiential learning, and field excursions are some of the instructional approaches. Materials include case studies, games, descriptive information, maps, graphs, and pictures. Topics covered emphasize student inquiry into current problems such as land use, development, pollution, and population. Among the titles for elementary grades are "Who Should Have the Neighborhood?"; "Moscow, Blueprint for a City"; and "Economic and Social Diversity Within the Urban Setting." Secondary grade materials include "What is All This Dam Foolishness?"; "Regional Planning: Focus on the Toronto-Centered Plan"; and "Game Playing with a Bite!"
