Quem dança com quemo desenvolvimento do raciocínio combinatório de crianças de 1ª a 4ª série
(2009) BORBA, Cristiane Pessoa e Rute
In the present study it was observed how Elementary School pupils understand combinatorial problems and what strategies they use. Different types of problems (Cartesian product, arrangements, permutations and combinations) were present in the test applied and answers were analyzed according to age and problem type. Progress was observed through different school grades. Arrangements and permutations problems were the most difficult, probably because of the difficulty in exhausting all possibilities, in which the order of presentation of the elements is important. Strategies varied from total incomprehension of the relations involved, passing by relation comprehension without exhaustion of possibilities, until the identification of the product that summarizes the situation. It is necessary to recognize that combinatorial reasoning may develop also out of school, being necessary emphasis on the total exhaustion of possibilities whilst solving these types of problems in the classroom.
