The "Arriba "Student Activities Manual, available both in print and within MySpanishLab, includes a vast number of practice activities, many of which are audio- or video-based, for each chapter of the text. It also contains speaking activities that are recordable in MySpanishLab. The activities are integrated and organized to mirror the corresponding textbook chapter. Each chapter of the manual includes a "Letras y sonidos" section, a "Perfiles "section, two "Cuanto saben?" sections, comprehensive activities on the "Observaciones" video segments, and a "Nuestro mundo "section.
