What is Leboncoin, and how do can it (and other similar websites) be used in a foreign language classroom?
Well, Leboncoin is a platform for exchanging goods, but can also be exploited as a platform for genuine exchanges.

This lesson-plan is based around authentic materials and a student collected corpus to help guide them.  Students are put into real communication situations, where they will have real and meaningful interaction in order to complete their tasks.  They will be exposed to different writing and communication genres, and will need to understand the suitable language “register” to use in these types of situations.
