Examination of the Number Sense Skills of Secondary School Students (6th-8th Grades)

The aim of this study is to examine the number sense skills of secondary school (6th-8th grades) students. The screening model among the descriptive research methods was used in the study. 366 secondary school students (6th-8th grades) in Ordu province participated in the study. The study data were collected by the number sense test developed by Kayhan- Altay (2010). The findings of the study showed that the number sense performances of the students were very low. It was determined that there was a significant difference in favour of the 8th-grade students in terms of the grade levels and in favour of the female students in terms of the gender in the number sense performances between 6th-8th-grade students and 7th-8th-grade students. On the other hand, it was determined that there was a significant positive relationship between the mathematical achievements and number sense performances of the students.
