This article synthetizes an applied research project that aims to develop iconographic analysis skills through the use of multimodal literacy in 2th grade high school students in preparation for the history unique test in 4th grade. The teacher gives himself a two-year perspective in order to develop in his students their ability to read images, one of the main weaknesses noted in 4th grade. The project has co-constructed several teaching and learning interventions through the school year soliciting different analogue and digital teaching and learning media (historical comics, web application for creating comics, etc.). In this article, this project is presented in the form of the 4Ps (portrait of the environment, co-creation process, project and production) to then identify the central contributions of the project with regard to three elements: skills in LMM, skills and declarative knowledge of the history and citizen education and the digital skill.
