Presented for teachers, clinicians, and parents is a manual describing approximately 700 activities to be used for language and cognitive development of culturally-deprived, mentally-retarded, hearing-impaired, and learning-disabled preschool or primary grade children. The communication processes in the manual are said to have been derived from the clinical model of the Illinois Test of Psycholinguistic Abilities. The format of the manual, which is divided into a section on curriculum and a section on language; the paginal cross-reference system; and the presentation of activities according to a hierarchy of increasing difficulty are explained. Suggestions are made regarding teaching style, activity management, and behavioral management through environmental structure. Directions, materials, and resources for activities that develop visual and auditory reception and association, manual and verbal expression, visual and grammatic closure, visual and auditory memory, auditory closure, and sound blending are given for the following curriculum areas: color, food, animals, toys, clothes, seasons, shapes, sizes and basic measurement, family, houses and homes, community helpers, senses, transportation, body parts, and opposites and analogies. Each section on an area of language to be strengthened, such as manual expression, is preceded by an introduction which defines the area, suggests a sampling procedure such as asking the child to show use of a comb to assess capabilities in the area, lists skills required for proficiency, and to illustrate approaches to arrangement of pictures or objects that are appropriate for activities.
