The Workbook has been designed as a complementary material for the class, offering the teacher and the student activities that can be developed in the classroom or assigned as homework. It is divided into 10 lessons that cover the same content as the Student's Book, either as a reinforcement of what has been learned in class or as an expansion of the topics addressed. The exercises are integrated, when necessary, with an icon in the Student's Book. The Teacher's Book recommends which exercises can be developed in class. The Workbook presents various activities, games, and pastimes to learn and practice Spanish in an enjoyable and fun way. At the end of the book, the solutions to all the exercises can be found. Sueña 3 corresponds to the B2 level of the Framework.
