This study has studied the impact of mathematics teaching (MEDMÖ), which has been supported by activities consisting of some mind-science games and logical questions, on mathematical success in ratio and percentage subjects of the students of the seventh class. Students’ opinions on the application were also studied. The application lasted seven weeks. In the study, the internal pattern, which is one of the research patterns of karma methods, was used. The research study group consists of two seventh classes studying in a secondary school located in the province of Elazığ in the 2018-2019 educational year. The study applied a mathematical success test (MBT) and a semi-configured conversation form. In the analysis of Nicel data, Mann Whitney U used dependent t tests and independent t tests. The data is subject to visual analysis. The application has been shown to have a statistically significant impact on the success of students in the ratio and percentage mathematics. In the interview, students expressed a general positive view on the application. They pointed out that with the application they developed their thinking, logical thinking and judgment skills. Together with this application, they have begun to think, use and understand their minds and have expressed their success in solving the new generation of problems that require logic.
