ALBARRACIN, Lluís  e  GORGORIO, Núria. Problematizing the estimation of large numbers: Modeling and the influence of context. Relime [online]. 2013, vol.16, n.3, pp.289-315. ISSN 2007-6819.  https://doi.org/10.12802/relime.13.1631.

This article introduces the problematization of estimating large numbers. We study the presence of mathematic modeling processes and the influence of context in problem solving that secondary education students propose. As a result of a qualitative analysis, we divided it into three categories: solution-focused question, strategies and a successful problem solving. This analysis allows us to study the relationships that exist between the strategies proposed by students and the context given when solving a mathematical sentence. We also study the modeling of those situations. From the data collection in this study, we implied that the context may influence the answers students propose for problem solving. We conclude that these kinds of problems may be used as a tool for introducing mathematical modeling in the classroom.
