Student's Book, Intro is the introductory level of the Interchange Fourth Edition series and is designed for beginning students needing a thorough presentation of basic functions, grammar structures, and vocabulary. Intro is based on the principle that low-level learning does not equal low-level thinking. The Student's Book contains 16 teaching units, progress checks, additional Interchange activities, and a Grammar Plus section that provides additional grammar explanations and practice. Included is a Self-study DVD-ROM that provides the full class video and extra practice with vocabulary, grammar, speaking, listening, and reading.
