The Greenfield Public School preschool programs are dedicated to the developmental philosophy, meaning that curriculum is based on the developmental level of each child, their learning style, and is individualized to the needs of each child. This is accomplished in varying ways including different activities for each child and open-ended activities for all children in which each child can respond in a way that he or she is able. The environments are designed to foster interaction among children and to promote "learning through doing" in an active and prepared setting.
