Abstract :This study aimed to investigate the measurement estimation strategies used by gifted students. Case study was used. 17 seventh grade students who were studying in the Science and Art Center located in a province in Eastern Anatolia Region of Turkey and who were identified as gifted participated in this study. The data was obtained through “The Measurement Estimation Skill Form” which includes nine open-ended tasks. In addition, clinical interviews were conducted with five students. The data were analyzed using descriptive analysis. The findings of this study indicates that students use eight different strategies, which rough guess ,breaking down, using prior knowledge, reference point, unit iteration, comparison with referents, subdivision clues and squeezing, in cases requiring measurement estimation. It was also found that while gifted students mostly used strategy “rough guess”, strategies “subdivision clues” and “squeezing” are used very little. Furthermore, the findings of this study show that gifted students did not use different strategies at the expected level in the measurement estimation situations.
