In each unit of the Teacher's guide, activities are explained in a clear and sequenced manner, and suggestions on how teachers can fully develop each activity are included. Ideas for optional extra tasks relating to the activities are also provided, together with all the answers and the audio transcripts. A wealth of additional resources for teachers are available online via the ELEteca platform (including photocopiable and projectable materials, tests, suggestions for group-based tasks, videos, and much more). Teachers can also use the resources on the platform to personalise classes and to monitor pupils' progress.
