The 14 lessons in this guide are intended to enhance elementary students' personal correspondence skills. The activities encourage creative personal interdisciplinary expression in language arts, visual arts, social studies, science, and mathematics through lessons that can be presented independently or integrated into existing lesson plans. Each lesson has a clearly stated objective and a "What To Do" section to get projects started. Additional sections include: "Communication Ideas"; "Suggested Art Techniques"; "Making Connections"; and "Book Suggestions." General information for teachers offers ideas for assessment, displaying student work, and cooperative learning. Mailbox activities provide correspondence information from the U.S. Postal Service and encourage correspondence networking and exchange. (MM)
