POMMER, Wagner Marcelo. The PI number and the concept of approximation: possible routes coming from History to Elementary Mathematics teaching. Ensino em Re-Vista [online]. 2019, vol.26, n.2, pp.345-365.  Epub Aug 31, 2023. ISSN 1983-1730.  https://doi.org/10.14393/er-v26n2a2019-3.

This paper aimed to present and discuss the question of approximation in infinite processes in the surroundings the History of Mathematics as a contribution to weave a possible significant approach of the PI number at basic education. The approximations theme constitutes a connection with rational numbers, since irrational numbers exist only in the pragmatic world through finite decimal representations. The search for documents in the context of the History of Mathematics revealed several moments of the ancient civilizations that allow a dialogue with epistemology, making a connection with didactic references between diverse mathematical themes, which allows the emergence of teaching situations immersed in a present-past feedback.

Keywords : History of Mathematics; PI; Approximation.
