In this study, a quality research method has been used to determine the teachers' views of the mathematical course in basic education. In this study, the quality research patterns have been used to study the situation. The study group consists of 15 class teachers. For the purpose of obtaining detailed data on the research problems, discussions were conducted with teachers identified using the maximum variety of sampling methods from the purpose sampling methods. In this study, a semi-structured form of conversation was developed to be used in the discussions that will be held in order to show the opinions of teachers. In the research, content analysis and visual analysis techniques were used to analyze the data obtained from interviews. Some of the findings from the study are as follows: when the teachers’ opinions are assessed on the mathematical lesson curriculum in basic education; when they are assessed adequately in general in terms of scope and content, some teachers have noted that they are insufficient and that they should be in accordance with age groups. As regards the number and nature of profits, some teachers say that they are too many, while some teachers say that they are insufficient.
