Contained in this teaching guide are two units that offer teaching strategies and activities for use with severely and multiply mentally impaired elementary aged students. The with severely and multiply mentally impaired elementary aged students. The guide is intended to provide structured experiences to foster the use of augmentative and alternative communication systems.

Activities are developed to build on three levels of performance/response: awareness, imitation, and self-initiation. Instructional methods stress precision teaching (task analysis) and effective group teaching. A sample classroom layout, instructions for making pillow chairs and a swing-out divider arm, and a sample schedule precede the specific unit on "back to school learning." The unit's four instructional objectives are (1) becoming familiar with staff, peers, and routine; (2) learning to use basic objects and equipment associated with school; (3) building a classroom "family'" and (4) building and strengthening each person's identity. Activities for this unit and for the "autumn antics" unit focus on "current events,""integrated arts,""discovery," and "home management." The "autumn antics" unit revolves around the concepts of autumn and apples, fall sports (football, World Series), fall leaves and their colors, and country life. Presented for each activity in both units are a general description, content area, materials, teaching suggestions (coded to behavioral objectives) and a form for recording the individual student's response to the activity. Instructional materials for duplication are appended to both units. (DB)
