This research focuses on the period marked by Modern Pedagogy hegemony in the country, therefore our analysis considers the implications of a renewed and modern education in arithmetic prescriptions. This historical analysis adopts the documents which regulated the reform as research's source. The study allowed to design an educational panorama where the pedagogical matrix of intuitive teaching, based on serial graded studies, characterized a new standard for arithmetic teaching in Santa Catarina School Groups.
