Mathematical modelling occupies a relevant place in international educational research. In this context, the present study deals with a mathematical modelling activity designed and elaborated from the theoretical approaches of both Fermi problems and Modelling Eliciting Activities (MEA's). The aim of the study is to describe and understand the processes of mathematical modelling through the productions and reactions of Ecuadorian primary school students (10-11 years old) when they solve one of these activities. A mixed methodological approach was used through an intensive case study design. The results show that students, despite having no previous experience with these activities, are able to understand the problem, make conjectures and assumptions, and propose ideas for solutions. It is concluded that these activities have great advantages for the development of modelling skills of students at this educational stage
