The aim of this research is to determine the impact of a differentiated teaching approach on the achievements and attitudes of primary-school third-class students in the math course. The research is designed according to the semi-experimental model of the pre-test-final test control group of quantum research methods. The study group consists of third-class students of a state primary school located at the lower socio-economic level of Adana or Ceyhan district. As a data collection tool, "matematical success test" and "matematical attitude scale" were used. In the study, t test analysis was used to compare students' pre- and post-examination test scores with independent groups. According to the data obtained at the end of the study, the success test found a statistically significant difference in the benefit of the test group in terms of the final test and durability scores. However, with students in the experimental group, the conclusion was that there was no significant difference between students in the control group’s pre-examination, post-examination and durability attitude points.
