When it comes to Teaching Mathematics in riverside spaces located in the city of Igarapé- Mirí-PA, it is faced with numerous difficulties that imply students' performance, for example: the lack of adequate didactic materials and motivating themes; the restricted access of students, due to lack of mobility and the distances between their homes and the school, in addition to the precarious conditions of these spaces. With regard to didactic resources, the main instrument used by teachers, in their teaching practice, is still the textbook. We understand, then, that the elaboration and use of concrete and manipulable materials, adequate to the students' learning needs are important alternatives to riverside schools, since they can be easily related to the experiences of these students. With this in mind, this dissertation aims to create an Ethnomathematics Laboratory in the Tocantina Amazon, which is a space for experimenting with school content related to the daily practices of students living in riverside environments. The riverside school needs spaces that promote the understanding of mathematical concepts and their relationship with instruments and daily practices and, in this sense, teaching laboratories fulfill this role. Thus, when we interact with riverside practices such as: fishing, handling and extraction of açaí, construction of houses and boats, in addition to the making and manipulation of instruments that assist in these practices, we are faced with opportunities to learn mathematics from the perspective of Ethnomathematics Education.And so, looking at the mathematical content from the traditional practices of the riverside communities, we propose to address the fundamental concepts of symmetry and proportionality to develop teaching materials. Thus, the work was developed based on the assumptions described by Vergani, when describing an ethical strategy to stimulate individual and socio-cultural development, D'Ambrósio when he portrays an Ethnomathematics from the point of view of the student's know-how, as well as the experience in socio-culturally differentiated environments and Bishop, who portrays mathematical enculturation, teaching mathematics from a cultural perspective. As a didactic product, result of this research, we propose the composition of a catalog with several activities developed for schools in riverside environments, didactic materials and methodological structures organized for the creation of an Ethnomathematics Laboratory in school spaces.

Um navegar pelos saberes da tradição das ilhas de Abaetetuba (PA) por meio da etnomatemática

The present work presents the final result of a qualitative research master's thesis developed in the Abaetetuba city (PA), specifically in the region of the islands of this municipality. The motivation for the research came from the author's immersion in a course of initial training of teachers to work in schools in the field that has been happening at the Federal University of Pará – Campus Abaetetuba and serves students from the communities of field regions and Islands roads of five municipalities of the lower Tocantins, Pará State. The research aimed to investigate how the knowledge of coastal tradition can contribute to an educational math education, without which these knowledge are conditioned to a mathematical concept institutionalized at school. The investigation was developed in three, of seventy-two existing Islands in Abaetetuba where we obtained the information through formal and informal conversations among the riparians, recorded in video, audio and pictures as methodological tools, in addition to the record of observations in field journal. Data were analyzed through the Ethnomathematics Program developed by D'Ambrosio (2001), after understanding what are knowledge of tradition and scientific knowledge, supported by authors such as Almeida (2009; 2010; 2012); Cruz (2007); Farias (2006). As well as the contributions of Santos (2003) in breach of some paradigms of modern science, which enabled the author to use Bicudo (2005; 2010) and D'Ambrosio (1996; 1999; 2001) because they presented sharp discussions on teaching Mathematics in Brazil, in addition to reading the National Mathematics curriculum parameters governing the teaching of Mathematics in Brazil. Galvani (2002), in turn, has contributed to important discussions on the training of teachers. In addition to finding in Morin (2010) the Foundation for the pursuit of education educational Math. The survey results indicate that the sociocultural context of Abaetetuba islands has a lot of knowledge of social, political, religious, and production that may contribute to the process of teaching and learning of mathematics in schools. Some of these knowledge go hand in hand with the school knowledge, establishing possible dialogues, especially those that are noticeable when looking at the visual. But, there are other knowledges that go in parallel, not just by the fact of not being easily identified, but because the school consider unimportant, pointing to a hierarchy of knowledge. Thus, there is a need to clarify that knowledge, as much as the school bordering, different as they are, seek to provide answers to the problems of the daily life of men and women.
