In this study, it is aimed at developing the concepts of step value of primary school 3rd grade students. The research is designed according to a group-free semi-experienced design, pre-test-on-test control. Students with difficulties in scale value have formed the research work group. The study group included eight students. Data collection tools have been used to test the scale of scale value, anxiety and attitude scale. In the application, computer-supported teaching materials developed by researchers were used. The experimental process lasted 2 weeks and a total of 6 lessons hours. After the experimental process, the work group was tested and the durability test was applied after 3 weeks. In the analysis of the obtained data related samples have been used the t-test technique. The analysis resulted in a significant difference between the study group’s pre-test and final-test average points in terms of the percentage value. It has been shown that computer-backed educational materials have developed the student’s understanding of step value. Anxiety and attitude variables from the student’s sensual characteristics have also not had a meaningful impact on computer-backed education. When it comes to the durability test scores, there is no significant difference between the student's final test scores average and the durability test scores average.
