O uso de letras na matemática: um estudo em uma escola do campo

Abstract

This work was carried out as part of the Regency and Field Research Internship of the Degree Course in Rural Education, held at the Joel Pereira Cunha Municipal Elementary School, located in the Sabino São Pedro Settlement Project near Vila Geladinho in the rural area of the municipality of Marabá / Pará; the work was developed with the 7th grade class formed by 15 students, with the theme The Use of Letters in Mathematics: a study in a rural school, the algebraic expression and the corn culture being the main elements of the research, having as objective to carry out studies through algebraic expression with the mathematical elements present in corn production. For the development of activities that took place in the classroom, having a theoretical class with the presence of a farmer who presents us with his knowledge as a producer of corn, a function he learned by accompanying his father from an early age on farming activities, as well as a practical class where there was the involvement of all students in the construction of a maize planting model, the research was carried out from the corn culture because most students also cultivate this cereal on their land, thus the practice of planting corn grain it is very present in the families of students, when exercising these activities, the elements of mathematics are observed in human activity and are often not even perceived; with this the research tries to show the study of the language of algebraic expression through the corn culture, showing the planting area as well as the time of preparation of the cereal, the use that the farmer makes of the mathematics for the planting in his property , thus being a generating factor for the construction of mathematical exercises that involves everyday life to think about algebraic calculations.
