The aim of this short teaching aid is to provide an introduction to the role and place of bi-and multilingual disciplinary literacies (BMDLs) in CLIL, more precisely in teaching Geography through English. This teaching aid is made up of 10 units, the first four focusing on theory, and the next six on practice. The first theoretical unit introduces the concept of BMDLs and their relations to Geography. It is followed by the explanation of the different dimensions of BMDLs in Geography. Unit 3 focuses on BMDLs in the CLIL Geography classroom, while unit 4 draws a genre map of secondary Geography. The second part of the teaching aid looks at some of the types of student output involved in the teaching of Geography through English. These are introduced through practical examples form the Geography matura exams in Hungary.
