Studies in Combinatorial Reasoning: investigations and practices K-12This paper presents research carried out over the past five years, by the Grupo de Estudos em Raciocínio Combinatório do Centro de Educação da Universidade Federal de Pernambuco – Geração. The group's research lines are presented in the paper, as well as the main theoretical references used. Investigation by the group on teaching resources are analysed, research results developed with students of different levels and types of education are presented and discussed, as well as studies with K-12 teachers. The set of results obtained enable reflections concerning how combinatorial reasoning develops, what are the difficulties to be overcome and how practices can be more effective in teaching Combinatorics.
