Resumen

In the last two decades of the 20th century and the first of this, the academic community has been reflecting about girls and boys as scientists. Some authors propose thinking the activity scientific as an activity cognitive that looks like what the children and girls make in the world that surrounds them. Within this approach, the development of scientific skills can assimilate to certain specific thinking skills of research processes. This work has as objective the development of a didactical proposal in the area of mathematics for the development of skills cognitive, starting from processes of research on the nutritional status of the girls and the boys, driving concepts as Index of Mass Body and Carving for the Age. The work was carried out with sixth grade students of education basic of the educative institution Felix Henao Botero of the city of Medellin, in Colombia. The area of mathematics was the base for the development of this project that also sought that the student acquires the basic skills of the course in the mathematical thinkings required for the grade. The paper presents the theoretical basic approaches in that it is supported the project, the structure of the intervention made, as well as the results obtained in front of the skills that they can develop.
