¡A que sí! Enhanced Fourth Edition is designed to encourage critical thinking and help you express yourself in Spanish. The Enhanced Fourth edition gives you an opportunity for in-depth exploration of relevant contemporary issues and revolves around four main themes: Espacios: Publicos y privados, Encuentros y desencuentros, Patria Nacion: Acercamientos, and De aca para alla. Each thematic unit is now supported by an authentic short film with accompanying engaging activities to inspire creative thinking and conversation. The short films and related activities can be accessed through iLrnAdvance, the online digital solution that accompanies the ¡A que sí! program.
