Abstract

This research, with a qualitative, exploratory approach, aimed to analyze the teaching of metric relations in the right triangle in the 9th year of elementary school in the perception of teachers in schools in São Raimundo Nonato-PI. For theoretical foundation, authors such as D’ Ambrosio (2011), Bassanezi (2006), Polya (1995) Miguel and Miorim (2011), among others, were used. The field research was carried out in two municipal schools and the instruments used to collect the data were: observation and questionnaire. The results corroborated the importance of diversifying teaching methodologies to streamline classes, highlighting the most appropriate methodologies for teaching metric relationships in the right triangle: Problem Solving, Games and Concrete Materials and ICTs, also highlighting the fact that limitations during initial training and the structure of schools that make the planning and development of these methodologies difficult. Therefore, improvements in school infrastructure are necessary, as well as the development of public policies for continued training that allow teachers to use different trends and methodological resources in teaching metric relationships in the right triangle.
