This work has as its central focus the analysis of the possibilities that Mathematical Modeling offers to the mathematical learning concepts in a class of an Agricultural Technician course in a federal institute of education situated in Alegrete-RS. The justification is supported by the possibility of adopting a teaching methodology which is able to create opportunities for students to have contact with everyday problems, developing the ability to solve them and to analyze and interpret the solutions and at the same time learn mathematical content. The proposed activities involved the modeling of field objects used in the work of a trooper who lives in the state of Rio Grande do Sul with the help of the software GeoGebra. The research was grounded in the ideas of realistic mathematics education proposed by Hans Freudhental and his approach to the ideas of mathematical modeling. The enquiry was operationalized, in a qualitative approach, based on data collected through interviews with the historian responsible for the Gaucho Museum of the city of Alegrete, participant observations of the activities with the students, reports of the subjects of the research informed in the Field Diary and documents produced by them. Based on the theoretical assumptions, their own reflections and research objectives established the data analysis. With the analysis it was possible to notice attitude changes during the research and the students commitment to the work developed. It was observed that the work with mathematical modeling based on a topic that is part of the students everyday lives and with the help of computational tools aroused the interest and motivation to study mathematical content as well as the development of abilities for investigating and understanding the socio-cultural role of mathematics.
