In the present study, those activities were updated taking into account elements from recent Brazilian investigations on the meanings assigned by Brazilian students of 1st-8th grades to relations and to order relations, and elements of the Brazilian Curricular Guidelines of 1997 and 1998. By applying the methodology of case study, and in the light of the notion of tool object dialectic of Régine Douady (1984), the updated activities were presented in eight sessions to two mathematics teachers of the 7th and 8th grades in a private school in the city of São Paulo, both of whom were experienced in working with this theoretical framework, with the purpose of investigating what aspects these teachers take into consideration when discussing and developing their lesson plans regarding those activities. Particular attention was given to the changes and adaptations they made to the activities in order to facilitate their use in the classroom, based on their teaching practice, the actual features of the school and educational system in which this study was conducted, the school s program, recent investigations conducted with Brazilian students, the Brazilian Curricular Guidelines of 1997 and 1998, and the theoretical framework developed by Douady. In the present study, this process has been termed reupdating / A partir de atividades de Régine Douady (1986) envolvendo enquadramento de números racionais em intervalos, voltadas a alunos franceses do segmento de ensino correspondente ao ensino fundamental do Brasil, realizou-se na presente pesquisa uma atualização dessas atividades, estabelecendo diálogo com pesquisas brasileiras recentes sobre significados atribuídos por estudantes brasileiros do ensino fundamental a relações e relações de ordem e com os Parâmetros Curriculares Nacionais de 1997 e 1998. Recorrendo-se à metodologia de estudo de caso, e à luz da noção de dialética ferramenta objeto de Régine Douady (1984), as atividades atualizadas foram apresentadas em oito sessões a duas docentes do ensino fundamental, de sétima e oitava séries, de uma escola privada da cidade de São Paulo, experientes no trabalho com esse quadro teórico, com o objetivo de investigar o que essas professoras levam em consideração ao discutirem e elaborarem planejamentos de aulas referentes a essas atividades. Foi dada particular atenção às alterações e adaptações feitas por elas a essas atividades, de modo a favorecer sua proposição em sala de aula, tendo em vista sua prática docente, a realidade escolar em que se realizou este estudo, o programa dessa escola, pesquisas recentes realizadas com alunos brasileiros, os Parâmetros Curriculares Nacionais de 1997 e 1998 e o quadro teórico de Douady. Esse processo foi por nós denominado de reatualização
