Abstract(s)Investigating mathematical knowledge used in everyday contexts of fishing communities has been our area of interest in mathematics education. Initially we investigated the fishing community of Câmara de Lobos (Madeira - Portugal) and later we also investigated the largest Portuguese fishing community (Caxinas - Vila do Conde in the North of Portugal). The initial purpose was to collect everyday mathematical knowledge of these fishing communities and then contextualize it within the curriculum documents that guide mathematics teaching. A second purpose was the development of mathematical tasks based on the information previously gathered from these fishing communities, for future use in the classroom.
