Abstract: The aim of this article is to describe, categorize, and classify the mathematical representations on paper of 5-6-year-old students and explanations about their experiences in two workshops on decomposition of the number 7 and to create a tool for interpreting and evaluating representations on paper on this topic. The participants in the study was a group of 24 early childhood education students from a school in Catalonia. The methodology was based on a descriptive-interpretative approach. The written productions of each student obtained from the workshops were analyzed and semi-structured interviews with students are carried out. The analysis were conducted in two phases: identifying the typology of productions and analyzing the mathematical content of the representations. The results reveal that students used pictorial, written, and symbolic language in their representations and that these languages often appear combined. Regarding mathematical content, a rubric was designed with six levels, considering a possible learning trajectory for the decomposition of the number 7.
