RESUMO

This research aims to investigate what teaching strategies, considering the use of a calculator in the classroom can become more efficient perception of mistakes in handling additive and multiplicative between students in a 7th grade of elementary school, in the afternoon shift of a State School in Osasco city S.P. (Brazil). This study consisted of a qualitative research as a tool with the use of two mathematical games: MAZE and HEX OF MULTIPLICATION. To achieve these games have used two hours/class of instruction for each one, the first without using the calculator. Thus, students enrolled in a sheet of paper paths (played) chosen using the additive and multiplicative. In our analysis, we point out that the mistakes made by most students when it comes to work with structures additive and multiplicative with decimal numbers were: a) adding or subtracting the decimal part of the whole, b) errors in the algorithm of division and multiplication c) errors in the positioning or absence of the comma d) subtracting tenths of hundredths. In the second hour of instruction, students played using the calculator, seeing their mistakes, beyond giving the results, providing opportunities for understanding the steps taken and opening new paths to knowledge. By assessing the strategies used in research on the foundations of Bianchini (2001) and Cunha (2002) and Bonanno (2007) and Rasi (2009) on the issue involving decimals, and additive and multiplicative, in the case of the use of games, we rely on research Grando (1995, 2000) and realize that such use involving the calculator, we allowed for greater efficiency in the perception of mistakes, and as our theoretical research by Penteado (2001) and Rubio (2003) and Borba ( 2005) and Schiffl (2006) and Borba et al (2008) and Sampaio and Leite (2008). Although these authors support the use of a mediator, there are various forms of resistance from many teachers in relation to such use. The argument used is that the student will not learn more mathematics, because no longer think, will do more calculations, nor shall the algorithms. Accordingly, we raised some discussions, which could help to illustrate the potential use of calculators and games in mathematics lessons. However, the analysis of collected data shows us that the practice of teaching mathematics gains new ground with the aid of games and calculator, which can facilitate teachers in their work to promote a more meaningful teaching of mathematics and the students a different view of use the calculator in the classroom
