Dealing with quantitative difference: A study with second graders

Résumé

The main goal of this paper is to understand students’ reasoning when solving a task that involves quantitative difference. A qualitative methodology was used within the modality of teaching experiment. The data collection was done through the participant observation supported by video and audio recording of the work developed by two pairs of second graders, as well as the records of whole class discussions. To analyse data, we organized them into two categories: additive comparisons and complex additive relationships. The results show that these students were able to deal with quantitative difference, establishing relationships between quantities, even in a situation where initial numbers were unknown.
