The journal Bulletin de l'enseignement de l’Afrique occidentale française was created in 1913 by Georges Hardy, then director of colonial school for a year, to promote the cohesion of the teaching staff through a system of collaboration. The aim of this paper is to study mathematics teaching in the French West African school system between 1913 and 1958, as seen through this journal. First, this paper will examine the place of mathematics in the African school system, both in importance and level, to compare it with the one of Metropolitan France. In particular, the examination test statements will be studied, and their level will be compared to the Metropolitan French ones. More qualitatively, we will look at impressions expressed by some authors on the level of students and teachers in West Africa. Then, we will focus on the official recommendations of the institutions concerning the content taught, the pedagogical methods and the resources. Among that, it is necessary to analyse the role of the European educational trends of the time (method of “the centers of interest”, Freinet or Montessori’s methods and “active pedagogy”) in the colonies. Finally, practices on the ground will be watched: the observation of the environment and the local population, the possible adaptation of teaching to the specificity of the territory and its inhabitants, and the various experimentations reported in the periodical. We will be careful to Hardy's ambition to see the birth of an “indigenous pedagogy”. This study is a way for us to travel through periods, personalities, and texts, just through reading magazines and staying on French soil. It is also an opportunity to see an example of how mathematics education has been impacted by a very particular historical and sociological context.
