Hi C., my son has been going to the Children's House of Bucks County Montessori school since his preschool years. It is a wonderful school. My son is now in second grade and he loves it. The children benefit from being in a room with other children that are slightly older or younger than they are. They learn from each other. My son was so excited the first time he gave a lesson to one of the younger children in the class. I have never seen him so proud of himself. They learn everyday activities like cleaning up after themselves and it really makes life at home alot easier. They also do arts and crafts and their whole philosophy is centered around creativity. Each child learns at his/her own pace. There are no dittos or worksheets, it's all hands on. I can't say enough about the staff and the teachers. You have to check it out.
They offer many different options for days/times depending on what you want. Toddler-Elementary. www.chbcmontessori.com
