The Student Activities Manual (SAM), thoroughly revised for this edition, includes workbook activities together with audio- and video-based activities, all designed to provide extensive practice of the vocabulary, grammar, culture and skills introduced in each chapter. The organization of these materials now parallels that of the student text, with an A primera vista section followed by En acción video activities, Funciones y Formas, Mosaicos, and Enfoque cultural. A new Repaso section in each chapter provides additional activities designed to help students review the material of the chapter as well as to prepare for tests.
