A primary annex, built to relieve overcrowding, is attended by children registered in kindergarten through grade 3. The building consists of an open area organized into a number of learning centers plus three closed classrooms. The school's program is based on two concepts adapted from the British Infant School system: (1) family or vertical grouping and (2) the integrated day. Family grouping divides the children into five parallel groups with similar numbers of children of each age level in every group. In an integrated day system the school offers a wide variety of creative, intellectual, artistic, and physical activities. Each child selects from the school's offerings to meet his own personal interests. Subject matter and time are not compartmentalized as in a traditional school. (MLF)
