Thanks to a collective letter exchange and in pairs of pupils, children from the classes and schools invloved in this project are offered the opportunity to discover a culture as well as a way of life different from their own, using French as a common language. This project allows pupils to identify similarities in our lifestyles, cultures, celebrations, school experiences and our perspective as future citizens or citizens-to-be while highlighting what allows us to distinguish ourselves from others. Thanks to this exchange, pupils are able to develop a lasting and obviously enriching Franco-Luxembourgish friendship.
