The research presents results of an investigation about the process of continuous training of teachers in service who teach mathematics in the initial years of Elementary School in schools of the municipality of Ponta de Pedras, in Marajó, Pará, Brasil. Researches indicate that in the early years of Elementary Education (aiEF), there is still greater emphasis on teaching other blocks that make up the mathematics curriculum, compared to working with Space and Form, more specifically, when compared to studies related to geometry. However, these same research points out the importance of teaching this content in aiEF. Faced with this problem, the question that emerged and which guided this research was how gemetry has been taught by teachers who teach mathematics in the initial years of Elementary School? In these terms, we present as objective, to investigate how the geometry has been taught by teachers who teach mathematics in the initial years in the municipality of Ponta de Pedras. To collect data were used questionnaire, audio recording, documents and logbook. The research was structured in two stages, applying a questionnaire that allowed to draw the profile of the teachers and to detect their experiences and experiences related to the teaching / learning of geometry and the planning and development of five training meetings, with the purpose of reflecting on teaching / learning geometry. In these terms, the research was carried out from March to November 2016 and had as participants a group of teachers and graduates of the Integrated Degree in Science, Mathematics and Language Education offered by the Institute of Mathematical and Scientific Education. As a final product, differential of this modality of masters, a proposal of continuous formation in service on the block Space and Form, in particular, teaching/learning of geometry for the initial years is presented.

This research objective is to identify, explain and describe to a better comprehension of how a teacher organizes and develops with the students the learning of geometry within investigative practices. As for the question that guided this project it was defined as: how teachers organize and develop alongside with the students in the learning of geometry within investigative practices. It was used as the theoretical foundation the ideas of Ponte among others, to approach the math related questions. The subject developed through investigative practice was the geometry of blocks – Space and Shape – in fifth grade. It is a qualitative research with an active approach, as for the analysis of collected data; it was used Discursive Text Analysis technique proposed by Moraes e Galiazzi. Interviews and audio recording were utilized as forms to gather data. The analysis shows that teacher while developing activities proposed under service instruction presented in your actions signs of investigative practice reshaping and producing a better engagement of students in the learning of geometry subjects brought to class; using tests, assessments, demonstrations, and validation. At the end of the research, an E-book was presented as a final product, arranged from the experiences with the activities developed by participant teachers during this research, aiming to be used by fifth grades teachers while targeting subjects related to the geometry of blocks, shapes, and forms.
