“Play is the work of the child.” – Maria Montessori
“The playing adult steps sideward into another reality; the playing child advances forward to new stages of mastery.” – Erik H. Erikson
Teachers and parents know that play is an important part of childhood, a belief that is supported by Erikson, Piaget, and Vygotsky. Play "...helps children to master issues related to affect, cognition, language, and/or social understanding."
