The Globe of World Parts (G 005) is a two-tone sandpaper globe distinguishing land from water by texture, serving as the child's very first introduction to geography in the 3–6 environment. Children trace the rough landmasses and smooth oceans with their fingers, building a sensorial impression of the Earth's surface before any labels or continent names are introduced. It anchors the entire geography sequence and is an essential foundational material for any prepared Casa environment.
