Apart from the usual 'compare your answers' (pair check), here are some ideas of how you could make IELTS preparation lessons communicative:
Listening
- Discuss a list of test strategies - valid or not valid?
- Discuss and justify predictions about some test questions, e.g. gap-fill and multiple choice
Reading
- Jigsaw reading - piece an article together (different paragraphs or sections of the article)
- Discuss and justify predictions about some test questions, e.g. multiple choice
Writing
- Writing Task 1 - work together to identify key features of the given visual(s), or even collaborative writing
- Writing Task 2 - brainstorm ideas and discuss/select ideas for writing
Speaking
Discuss a list of test strategies - what's valid and what's not
Discuss and justify predictions about some test questions, e.g. gap-fill and multiple choice
