This lesson on language occurs in a unit on culture. The student text introduces the term 'communicate'.
Students discuss gestures and symbols as forms of communication.
The teachers' notes foster the insight that for communication to take place, both sender and receiver must understand the gestures and symbols. Advantages of maps and universal symbols are suggested. Human and animal communication are compared. It also stresses how language enables us to speak of the past and the future, as well as how the written word helps us preserve human experience. 1976 by Houghton Mifflin.
