In this paper, we report the development of a research project with students in 8th grade of elementary school, with context problem solving for the teaching of polynomial functions of first degree. The research is qualitative and used the of Teaching-Learning-Assessment methodology for problem solving. The research aimed to examine the possibilities of working the concept of function with students in 8th grade of elementary school, through the solution of problems related to cultivation of agricultural products. We worked with 22 students from a rural school located in the municipality of Candelaria, RS. In collecting data, was made use of questionnaires, with mixed questions and observations of activities. The project had three stages: first, we applied a questionnaire to collect data on agricultural production of students' families, in the latter, there was a talk of a technical from EMATER, about the cultures, and in the third stage we developed with the students the sequence of planned activities. It was found that students, at the most, correctly solved the problems directly linked to data for crops, but failed to respond properly to problems involving the laws of the functions or graphical representation in a system of Cartesian axes. In the activity of discussing data provided by the technical, it was noted that students were motivated, discussed and took the information for applying in their families´cultures. We conclude that in applying contextual issues is necessary, first, to review prerequisites concepts, so students have more autonomy in the resolutions and understand the contents involved. As a suggestion for application in other classes, we constructed a sequence of activities, with problems related to the cultivation of tobacco, corn and beans, presented as the product of this research, available also on CDROM.
