The teacher observes and works with individual children, introducing materials and giving guidance when necessary. Through careful observation, the teacher prepares the classroom environment as necessary to aid each child's growth. The teacher continually assesses the direction in which a child has indicated he or she wishes to go, and actively works to help the child achieve his or her goals. In the upper levels, the teacher conducts group lessons in reading and math on a regular basis, as well as group lessons on cultural subjects.
