Abstract

This experience report deals with the application of a practical assignment from the Problem Solving subject in the 1st year of the Mathematics course at UNESPAR - Paranavaí Campus, with the aim of measuring the area of a small square located in the city of Paranavaí near the school where the activity was developed, based on the students' previous knowledge and problem-solving skills. The activity was carried out at the school with a group of 2nd year high school students, where the class was divided into groups and each went to an external location to carry out the activity on site. Once the measurements had been taken in the triangular square, the academics and the group of students returned to the school and carried out the other stages of systematizing the problem-solving activity in the courtyard. Throughout the activity, we were able to observe the students' line of reasoning, the main strategies used and understand and try to resolve their main doubts about the content of plane geometry. The experience allowed us to get to know the students' main difficulties in relation to mathematics and problem solving and to find the approximate area of a square using alternative resources.
