ab: 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.
