The Teacher's Book has been designed as an essential material for teachers, as it presents methodological issues and explains how the proposed exercises work. It details the steps that should be taken to develop the activities and expand upon the statements of the Student's Book. The pages of the Student's Book are reproduced in the Teacher's Book so that the teacher knows where they are working.

It groups together all the elements that make up the Sueña 2 course in its explanations. It proposes how to integrate the Workbook into the learning process, indicating when an activity from the Workbook should be carried out in class and when it should be assigned as homework. References to the Workbook exercises indicated in the Student's Book by an icon serve merely as a suggestion for the student, in case they want to continue practicing the same content in the Workbook exercises.

Additionally, the transcriptions of the audio exercises from the Student's Book are included, along with explanations on how they should be listened to and worked on. As supporting material, two audio CDs with the recordings from the Student's Book are included. Sueña 2 corresponds to the B1 level of the Common European Framework of Reference.
