There are two principal concepts of geography in the Children’s House:
- The earth is broadly composed of land, water, and air, with land and water being the major focus of study.
- The large earth may be three-dimensionally represented as a globe, or
may be two-dimensionally mapped as on the puzzle maps. Landforms
may be three-dimensionally represented in clay and water, or may be two-dimensionally
mapped as with the blue and brown paper cards.
