Interactive is an exciting four-level course for teenage learners from elementary to upper-intermediate levels (CEF A2-B2). The Workbook provides additional practice in the language introduced in the Student's Book. Portfolio sections offer an alternative writing activity and there is one core listening text, plus additional listening practice for each unit. Vocabulary practice for every unit is extended further. 'Help yourself' boxes highlight key grammar points and offer extra language practice. A 24-page grammar section at the back of the Workbook offers a 'Grammar Reference' and 'Grammar Practice' linked to every unit of the Student's Book. The audio to accompany the Workbook is available from the course website: cambridge. org/elt/interactive | Interactive Level 3 Workbook With Downloadable Audio by Meredith Levy, Boxed Set/Slip Case/Casebound | Indigo Chapters
