PALMAS, Santiago  and  BLOCK, David. Access to a written representation of natural numbers: a didactic sequence for adults with little or no schooling. Relime [online]. 2014, vol.17, n.2, pp.165-189. ISSN 2007-6819.  https://doi.org/10.12802/relime.13.1722.

This paper points out the difficulties in adults with little or no schooling when teaching mathematics. Our objective is to contribute to the spread of didactic alternatives for adults regarding the conventional written representation of natural numbers by recovering their former mathematical knowledge from their daily lives. This kind of knowledge is not often expressed in a written representation but in an oral one. The study includes a formal experience of didactic engineering with an adult with no schooling and from a rural area.

Keywords : Adult education; Numbering; Semiotic data; Didactic of mathematics.
