National Curricular Parameters

A so boarded subject in all the areas of the knowledge, since a simple preference of a group for determined modality of sport until the one field research the vote intentions, the graphs occupy some the first pages of magazines and periodicals. A reporter is common during a esportivo program divulged the probabilities of one definitive teams of champion soccer to be regional in the dispute of the turn and returno for run points. Data are presented in percentage, later a comparison are made through graphs, indicating the club with bigger possibility. Daily periodicals circulate for the cities, have a specific notebook for economic subjects such as: inflation, trade balance go up, it and go down of the dollar, given are grouped in tables. When turning pages the periodical, exactly not making a refined reading of the subject, if the reader to be intent to tables and graphs, will be able to make comparisons, to take off conclusions if to relate given with the heading or subject of the subject being able to be along with the facts. However, so that this mathematical language is dominated is necessary that it has the proposal of daily situations on the part of the professors so that the pupils can interpret to this type of information who constantly are gifts in its lives.

The National Curricular Parameters of Mathematics for Ensino Fundamental (PCN) detach the importance in the treatment of the information in relation to tables and graphs. With regard to the Statistics, the purpose is to make with that the pupil comes to construct procedure to collect, to organize, to communicate given, using given, using tables, graphs and representation that appear frequently in its day-by-day. Moreover, to calculate some statistical measures as it measured medium and fashion with the objective to supply new elements to interpret given statisticians. (PCN, 2001, p.52). The document above points the importance of appropriation of the knowledge, abilities and abilities in constructing and reading tables and graphs in the education of the pupils, therefore currently is a subject that daily is explored in the medias that reaches the most diverse social classes. The fact cannot be dealt with disdain.

We must point out that it is of basic importance, when is studied given statistician, to alert the students on the types of tables so that they are delineated the differentiations for the graphical conversion well. On the other hand, when it has conversion of data tabulated in graphs is cautious with certain frequency to guide the pupils who are 0 variable that if relate, indicating comparisons that can be gotten. However, in the construction of a graph it is necessary that if it makes a detailed analysis of the data to opt to that one that is convenient the situation proposal. Some types of graphs are very used, as of bars, of columns, of line and of sectors. To propitiate conditions so that the students can construct them and interpret them and use them as part of the mathematical alfabetizao in daily real situations are a challenge of the educators of this new millenium pautado for an education of quality. It will be cautious to only mediate the knowledge of the statistics in average education? Or, we must dissimulate blind people and contribute for a functional illiteracy?
