The full-colour Teacher's Book comes with facsimile pages of the Pupil's Book and Activity Book. An Aims box for every lesson specifies objectives, new and recycled language, materials needed, the Basic Competences that the pupils will achieve, and home-school links. Clear instructions are provided for every lesson along with audioscripts and answers. The Teacher's Book also offers a vast array of extra activities, with warm-up, ending the lesson and extension and reinforcement activities. Unit tests help assess pupils' knowledge with a listening, speaking, pre-reading/reading and writing test. The tests are presented in a familiar way with illustrations and simple activities.
