The Workbook/Lab Manual has four major divisions: (1) listening comprehension exercises that expose the student to the vocabulary and grammatical structures of each unit in a variety of new situations; (2) oral activities for review and reinforcement of the grammatical concepts presented in each unit; (3) controlled and open-ended written exercises using the same vocabulary and structures; and (4) writing practice. The Answer key for these exercises and the Lab Audio script are on the Premium Website in order to give instructors the choice of offering students the opportunity for immediate self-correction.
