| Sumario: | The aim of this study is to examine the number sense strategies used by 6th grade students during solving percent problems. Number sense is the ability of flexible applying number and operation information in mathematical cases. The students use benchmark, round off numbers and approximately guess the numbers, compose/decompose the numbers without the written operations or rules in order to find the result using number sense ability. A total of 30 (15 male, 15 female) 6th grade students from a preliminary school in the province Sakarya participated in this study. A test consisting of 8percent problems are used as the data collecting instrument. The students are asked to explain their solution method after having solved the problems. In data analysis, at first the answers are examined and it is decided that the answers are right or wrong. In the second part of data analysis, the strategy the student used is determined. The strategies are coded as number sense based, rule based and answer given or not. By examining their solution methods, it is determined whether the strategies they used were number sense based or rule based. As a result of the analysis, it is revealed that 60 (25%) of the solution methods used by 30 students to the 8 questions were number sense based and 138 (57,5%) were rule based. This result has shown that the students, participated to the study, are tended to use rule based strategies and cannot use number sense strategies sufficiently while solving percent problems. |
