BURIGO, Elisabete Zardo; ROSA, Nícolas Giovani da  y  SILVA, Mayara Becker Oliveira da. Skirts and blouses: inventions to learn how to multiply with Modern Mathematics. Educação. Porto Alegre [online]. 2019, vol.42, n.2, pp.245-256.  Epub 21-Ene-2020. ISSN 1981-2582.  https://doi.org/10.15448/1981-2582.2019.2.33793.

The article presents an investigation about an innovative experience of mathematics teaching registered in a notebook of a student who attended the second year of the primary school of the Institute of Education General Flores da Cunha in the town of Porto Alegre in the year 1968. It is an approach of multiplication inspired by the cartesian product of sets concept and oriented to what is currently termed combinatorial thinking. The institution, dedicated to the training of primary teachers, offered a Course on Modern Mathematics Didactics in the Primary School since 1966. Through the cross-referencing of several sources, the research identifies connections between the experience recorded in the notebook, studies promoted in the Course and publications of authors engaged in the Modern Mathematics movement. Considerations are also made on the curriculum practiced in that school, on the creative power of the school culture and on the resonances of Modern Mathematics in the current productions on the teaching of Mathematics for the early years of the schooling.
