At The WonderKey School we know that young children learn best through hands-on discovery in an environment that offers a variety of opportunities for child-directed exploration. Our curriculum,  'cross-walked' with the Pennsylvania Early Learning  Standards, is unique to The WonderKey School and has evolved over many years. The Pennsylvania Early Learning Standards guide us as we plan for developmentally appropriate activities for the children and families that we serve. Our goal is to capitalize on children’s interests and strengths while developing new skills and maximizing each child’s opportunities to learn. Individual, small group and large group experiences are offered in the key learning areas including; Learning Through Play, Early Literacy Foundations, Creative Thinking and Expression, Cognitive Thinking and General Knowledge, Scientific Thinking and Technology, Social Studies Thinking and Health, Wellness and Physical Development.
