The traditional classroom design is very similar to the grid-like design of a chocolate bar. Figure 1 illustrates this idea through a bird’s eye view, looking at the classroom’s layout from above. On the left-hand side, notice the entry door into the classroom, with the cubbies in the lower left corner. Directly across the room from the entry door is the exit to the outside play yard. Along the top of this image are several windows looking outside, and on the bottom are two doors to the children’s restrooms with a teacher’s sink and cabinets in between.
