Interest centers are designed to meet the needs of the other children in the class while a small group works with the teacher on the Oral Language Program. This manual is intended to assist teachers in organizing the centers, which will be used for about an hour each day. Arrangement of furniture is discussed, suggestions are made for an art center, library center, and self-instruction center, and the daily routine for using each center is outlined. Detailed lesson plans are provided for the first 10 days, with suggestions for further activities. Four appendixes explain how the services of a teacher aide can be used, how to prepare "thinker boxes" of activities and games to develop concepts and skills, the possible extension of interest centers to include sand, water, woodwork, house area, and building block activities, and sample plans for the arrangement of the classroom.
