This document consists of three separately published fact sheets combined here because of the close relationship of their subject matter. The first fact sheet, "Communication Interactions: It Takes Two" (Kathleen Stremel), defines communication; suggests ways to find opportunities for interactive communication; offers specific suggestions for improving interactions (such as interacting often, allowing the child to participate in as many activities as possible, and providing examples for others); and gives an example of communication interaction. The second fact sheet, "Expressive Communication: How Children Send Their Messages to You," defines expressive communication, lists reasons to communicate at an early age and at a later age, explains use of a communication map to assess the child's expressive communication, recognizes the progressive nature of communication development in planning an individualized program, and presents guidelines for developing an effective communication program. The third fact sheet, "Receptive Communication: How Children Understand Your Messages to Them," defines receptive communication, offers tips for sending effective messages, and explains the use of a communication map to evaluate the child's current receptive language abilities and to design a program for the child based on his/her hearing and vision, motor abilities, and cognitive abilities. Each fact sheet also includes an annotated list of suggested resources. (CR)
