In the courtyard, on the sidewalk of a quiet side street or a dead end street, on the terrace a child lies on the ground.
Then his body is bordered with the street crayon. This can be done by an adult or by another child. Paint out an outline of each child.
Each child can then look at his or her body. Differences can be discussed together, such as who has the smaller feet or who has longer arms. The children can then paint a face and hair or even clothes or a crown.
