I’m not aware of any existing material to practise the four skills on the topic of Dickens. I’m afraid you’ll have to prepare your own material and design the exercises.
I’m guessing that your lesson plan is for an observed lesson that will be evaluated. If this is correct, you could ask your tutors whether they know of any material that practises the points you mention. Preparing materials yourself can be very time-consuming and it’s best to avoid this when doing an observed lesson for a teaching qualification – just to go easy on yourself.
If you wish to go ahead with this and don’t find materials, I suggest you use a video of a Dickens book along with the book itself. The BBC have produced some very good adaptations. Choose a scene that is light and fun. You might also want to check whether the BBC have produced anything for learners of English to accompany your chosen programme. You could ask the students to read the scene with some comprehension questions and some work on difficult language. Students can then imagine they are TV producers and they decide in groups how they will interpret the scene; ideas include: who will play the parts? Where will it be filmed? What will be on the set?….. Students present their ideas to the class and then watch the video recording and compare it with their ideas. These tasks will practise listening, speaking and reading. You could follow this up by asking students to write a review of the BBC recording either in class or for homework, depending on how much time you have.
All the best,
