Résumé
This paper presents a first step for designing language support for Grade 9 students working collaboratively on the topic of similarity, more precisely an adaptation of Brousseau’s tangram task. The qualitative study identifies (topic specific) language means which students use for talking about their ideas on how to enlarge figures, combining geometrical and arithmetical ideas. Furthermore, a textbook analysis shows the target language that students should use and understand at the end of the teaching unit. The identified difference between both repertoires of identified language means calls for developing language-responsive teaching-learning arrangements in the future in which both language repertoires can be bridged systematically by macro-scaffolding trajectories.
