Summary: We analyse the representations used by grade 3 students and how they relate to mathematics reasoning on a mathematical problem. Data were collected through audio and video recording in the classroom as well as students' written productions. Students that use schematic representations are those who have more success in solving the problem, in contrast with those that use pictorial and symbolic representations. The reasoning of some students shows interesting instances of making generalizations and working in a systematic way.
