The document compares and describes several popular preschool curriculums: Montessori, Waldorf, Reggio Emilia, High/Scope, and Bank Street. Montessori uses child-centered, guided learning where play is the vehicle for academics. Waldorf is play-based with mixed-age classrooms and no media/academics. Reggio Emilia is project-based and encourages child-led discovery. High/Scope follows a plan-do-review routine with interest areas. Bank Street balances child and adult activities using mixed-age classrooms.
