This article, which takes the form of a documentation of practices, reports a co-creation project resulting from a multimodal literacy research-design: the creation of a comic book in class with a historical character. During this project, 6th grade elementary school students produced a multimodal work (text - images) to learn about 1) the 1900-1960 historical period and 2) the complete realization of a comic book. In this article, we present this co-creation project according to the 4Ps approach (portrait of the environment, process of co-creation, project, production). We conclude by presenting several observations. Among these, we identify students’ motivation stimulated by the project and the development of multimodal literacy and several social universe skills: decoding and critical reading of documents made of images, literature research, reception/production of semiotic information by combining text and images.
