Resumo: The paper concerns the construction of the combinatory reasoningwhen problems of Cartesian product are solved by 3rd to 6th grade ElementarySchool students’. Stemming from the revision of hierarchies described in earlierstudies, it is based on Piaget’s and Vergnaud’s proposals. The participants, 110students attending State Elementary Schools (mean age 10;5), answered a paperand pencil instrument containing four multiplicative problems of Cartesianproduct. A qualitative and a quantitative analysis result in a revised hierarchy ofthe combinatory reasoning, and show its absence on solutions in all grades andproblems, but a significant tendency to advanced solutions in 4th grade to someproblems. Concerning the hierarchy, the discussion underlines the progressivecombination of variables; the passage from arithmetical to algebraic reasoningand from additive to multiplicative schemata; the progressive overture to thepossibilities in its interplay with the necessities. Methodological restrictions andimplications for mathematical education are presented.

O trabalho decorre do reexame de hierarquias descritas em estudos anteriores, com base em proposições de Piaget e Vergnaud. Os participantes, 110 alunos de escolas públicas (média etária 10;5), solucionaram por escrito quatro problemas multiplicativos de produto cartesiano. A análise qualitativa e a quantitativa dos dados permitiram: redefinir patamares do raciocínio combinatório; apontar ausência de raciocínio combinatório nas soluções em todas as séries e problemas, mas tendência significativa a soluções de níveis mais adiantados na 4ª série em alguns problemas. A discussão destaca na hierarquia descrita: a combinação progressiva das variáveis; a passagem do raciocínio aritmético para o algébrico e a dos esquemas aditivos aos multiplicativos; marcas da progressiva abertura para os possíveis em relação ao necessário. Restrições metodológicas e implicações para a educação matemática são apresentadas.Universidade Estadual de Campinas2010-12-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionTexto info:eu-repo/semantics/otherapplication/pdfhttps://periodicos.sbu.unicamp.br/ojs/index.php/zetetike/article/view/864669810.20396/zet.v18i33.8646698Zetetike; Vol. 18 No. 1 (2010): jan./jun.
