Social development is fostered by a classroom where children feel safe and mutually accepted by each other and the adults who are working with them, and also by an arrangement of the furniture - desks and chairs - where appropriate conversations can take place. The teacher and students together - early on - should set the rules for interaction. It is better when these rules emerge from the students and, of course, are reasonable ones. The teacher can also foster development by allowing student leadership, and fairly rotating it, such as in distributing supplies and leading the lunch line.

1. Organize activity spaces in the classroom so at least 3 children work/play together to give the children places to practice interacting with each other. For example, in the Blocks/Building Area, children cooperate with each other and respect the others' space to play.
2. Have a place in the classroom, or activities outside, in which only one child works at a time to promote waiting for one's turn and stopping at a given time. For example, computer time, only one of a certain trike, using a favorite truck or dress-up item.
3. Use a "Helping Hands" bulletin board to promote pride in the classroom, by helping keep it organized, clean, and safe.
