The aim of this dissertation was to investigate 4th grade children's skills in reading and interpreting graphs as well as their conceptions of the statistical measure mean. More specifically, the study addressed the research question: What are the contributions of a teaching intervention based on the use of manipulative materials to the teaching and learning of elementary statistical concepts the primary school? To this end, an interventionist research approach was adopted in a study involving two classes of the fourth year of "Ensino Fundamental" in a public school in São Paulo. One class constituted the control group (GC) and the other the experimental group (GE). The field research was organised in two phases the administration of diagnostic instruments (pre- and post-tests) to both the experimental and control groups; and the teaching intervention, which was applied only with the experimental group. The results from each phase were analysed in relation to two research foci the reading and interpretation of graphs and the concept of arithmetic mean and in relation to the types of graphs used vertical-bar graphs and "two-entry" graphs (as represented in the software Tabletop). Analysis of the results indicated student difficulties in the reading and interpreting of graphs in particular situations, such as graphs with non-unitary scales and/or with null frequency; The reading and interpretation of two-entry graphs was not associated with major difficulties. For the arithmetic mean, an increase of almost 50% in students' performance was observed from comparisons of the pre-and post-test results. On the basis of these results, it appears that the teaching intervention enabled the development of strategies for solving the presented situations as well as favouring the forging of important relations between the two concepts investigated, which influenced the amplification of students' knowledge of Data Handling
