Resumen
O objetivo desta pesquisa é caracterizar o uso das ações de divisão e iteração na construção do conceito de fração imprópria em um contexto contínuo em alunos do ensino básico 9-12 anos de idade. 138 alunos de escolas primárias responderam a um questionário com tarefas centradas na representando frações impróprias. Os resultados desta pesquisa indicam que al representar frações impróprias os alunos coordenam as operações de dividir em montantes partes iguais e iteram a fração unitária. Os resultados desta pesquisa apóiam a hipótese de que os alunos devem superar a ideia de frações como partes de um todo para coordenar os diferentes níveis de unidades para representar frações impróprias.
