"Play is a form of education that traditional schools excluded because it seemed to have no functional significance," Jean Piaget once observed. Play was considered merely a rest or a release of surplus energy. This simplistic view neither explains the importance children attribute to their games nor the consistent form that children's games take, the symbolic or imaginative inventions (J. Piaget - Psychologie et pédagogie). The experiential, functional, and expressive aspects of knowledge and expression of the child within every student, the human development of cognition that leads from elementary sensations, movement, and speech, logics that contribute to the emergence of the individual, are fundamental prerequisites for a modern – progressive formation of systems and methods capable of producing situations that transform stereotypical data with tools of imitation, movement, and the child's perceptions through the conversion of a mental image into action. Events and incidents, behaviors and needs that concern a child, should interest every educator, teacher, psychologist, and theater expert. This book aims to move in this direction. Using the tool of Theatrical Play – theater pedagogy as a social and cultural asset. Because authentic Theatrical Play can function as a multi-tool, a lesson, a vehicle that can contribute as a method, assist children, and lead them to approach and familiarize themselves with the theatrical phenomenon. Because theater is a complex, social, and intensely educational art. "All the world's a stage" (William Shakespeare), and on this stage, children cannot be absent. As long as there are still "children."
