The knowledge of your child with the concepts of "high" and "low", "above" and "below", "bottom" and "top"? You've probably already explained to him what they are. Now try to consolidate this knowledge. While walking let the kid calls high items and low, compares them in height: this house is higher than the other, the bus above the car, the cat runs down, the bird flies at the top. At home you can continue this lesson: the Palace at the bottom, on the floor, the chandelier above, on the ceiling, a table above the chair, a Cabinet above sofa, etc.
