Ethnomathematics: the Mathematical Knowledge of the Shintuya Native Community - Harakbut People of Madre de Dios, 2023

Objective: The objective is to investigate the mathematical knowledge implicit in the cultural and pedagogical practices of the Shintuya Native Community, Harakbut People of Madre de Dios, in order to unveil the mathematical knowledge present in the culture and educational practices. Theoretical Framework: The theories highlighted in ethnomathematics are: Ubiratan D'Ambrosio's Theory of Ethnomathematics, Gorman and Balter's Culturally Sensitive Parent Education, and Weinstein, Tomlinson and CurranView's Toward a Conception of Culturally Responsive Classroom Management. Method: The methodology adopted comprised the qualitative approach, grounded theory and ethnographic method. Data were collected through interview, observation and documentary analysis. Results and Discussion: The results revealed that mathematical knowledge is integrated in practical activities such as: land measurement, calculation of planting times and elaboration of patterns in handicrafts; promoting sustainable management of natural resources. This practical learning is transmitted by adults and elders in a pedagogical process based on observation and oral tradition, where young people apply concepts of quantity, form and proportion, while reinforcing values of respect and balance with the environment. Research Implications: It reveals implications in areas such as: Education, revaluation of ancestral knowledge, intercultural education; Cultural, strengthening of cultural identity; Social, inclusion, equity and community development. Originality/Value: This study contributes to the literature, providing new knowledge on the ethnomathematics of a cultural group that has been little studied. The relevance and value are evidenced in the rescue of ancestral mathematical knowledge, understanding of cultural diversity and design of pedagogical strategies.
