It is only a reading text about history of pizza. It is appropriate for intermediate students. You formulate some questions about the text and give it your students. The text has been simplified to suit intermediate students. You can also design a pre-reading task and a group discussion task about favourite dishes. You can also design a writing task in which students are asked to write an essay about their favourite dish or their country's traditional dish. This way you can cover all three language skills reading, writing and speaking.
