Unlock 4 Listening and Speaking Skills Student's Book and Online Workbook

Unlock is a four-level academic skills course that combines thought-provoking video from Discovery Education™ with carefully scaffolded exercises and a fresh approach to critical thinking skills. Unlock Listening and Speaking Skills Level 4 provides 60-90 hours of classroom material. Access to the Online Workbook is provided via a code packaged with the Student's Book. Critical Thinking sections give students frameworks to formulate their own opinions and express themselves effectively in the end-of-unit academic tasks. Unique research into common learner errors (using the Cambridge English Corpus) focuses the language used in Unlock on those areas learners find most challenging.
