Abstract

The objective of this work is to apply a series of activities approaching a content of Plane Geometry, more specifically, quadrilaterals. Geometry is one of the areas of mathematics and is present in the high school curriculum. Many objects around us have a geometric representation, and, in this way, students can see it applied in their social context. In this work, a differentiated class was presented, showing examples of geometry application. Calculating the area of ​​plane figures is a way of understanding the size of a given space. Thus, land allocation is carried out from the measurements presented in flat figures and results in an area that, in rural areas, is called a task. It was discussed how land cube calculations are developed, through the resolution of mathematical problems. For this research, a qualitative approach was taken. Data analysis was performed according to the students' answers in solving the mathematical problems. Therefore, this work opens space for an analysis and discussion about everyday mathematical knowledge present in different cultures, which can be adopted as an integral part of the local curriculum, contributing to the understanding of mathematical concepts and applications in the social context.
