This thesis examines the occurrence of multilingualism in three Swedish educational aids. A both quantitative and qualitative content analysis has been carried out, in order to find out in what way multilingualism is portrayed in the digital educational books, whether it is described as a challenge or not, to what extent multilingualism is mentioned implicitly versus explicitly and last but not least, if emphasis is put on multilingualism connected to words or speakers. Sweden is a multicultural society, with students of different ethnicities, speaking different languages. By carrying this study out, it will show whether these students are included in the teaching materials or not. Results show that the word multilingualism itself is not mentioned explicitly more than four times. Moreover, the educational aids seem to put more emphasis on speakers rather than words. Also, it is made clear that multilingualism does, to some extent, challenge the Swedish language. As for the concept itself, it is mostly described as a phenomenon connected to people who speak more than one language.
