The primary contribution of this paper is the finding that lack of activities and interesting learning areas prepared by the teacher in the classroom may negatively impact children's social behavior. Classroom design and the teacher's careful selection of materials to be displayed in each of the learning areas do engage young children in learning activities during learning sessions and their free time. When children group themselves according to their interests in different learning areas, they develop various skills and positive attitude towards each other in their groups and all members of the class. Children engagement in different learning areas in their classroom develop and improve language skills, reading skills, listening skills especially during dramatization, numerical skills, acquire general knowledge in various subjects including sciences and their mother tongues. In a participative classroom, children learn how to share and take care of the materials in their learning areas. While in their learning centers, children develop manipulative skills, leadership and managerial skills, learn how to tell simple stories, and learn how to work together as a team. A friendly classroom develops an environment that creates a desired children's social behavior.
