The purpose of this study is to investigate children's cognitive maps of school buildings. Sketch-map and placings of specific locations of floor plan were employed to externalize children's cognitive maps. The subjects were the second, the third, and the fifth graders. Some of second graders' maps seems to be as accurate as fifth graders' ones in the placings of specific locations. In one school building, the block slanting at 45 degree angle was distorted to be at right angle and pararell about 30 children's cognitive maps. In the other school building, about 10 children's sketch-maps indicated rotated distortions.
