The brand new WorkFiles function as an extension of the textbook with activities and exercises that are cross-referenced at specific points in both the student text and the Annotated Instructor's Edition. The WorkFiles empower you to customize the program to fit both your specific teaching needs and your students' varied learning styles. Simply choose from one of the many sections to suit your curriculum goals, teaching style, or the learning styles of your students. WorkFiles now include the Workbook, the Lab Manual, Vocabulario suplemental activities, Gramática suplemental activities, Práctica comunicativa activities, and Realidades en video activities that are tied to the all-new reality-television based Intercambios video program.
