Interchange Fourth Edition is a four-level series for adult and young-adult learners of English from the beginning to the high-intermediate level.
Workbook, Level 1 has six-page units that follow the same sequence as Student's Book, Level 1. The workbook helps recycle and review language by providing additional practice in grammar, vocabulary, reading, and writing. It is appropriate for in-class work or assigned as homework.
Student's Book, Level 1 builds on the foundations established in the Intro level for accurate and fluent communication, extending grammatical, lexical, and functional skills. 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.
