This study was conducted to determine the perceptions of kindergarten children, primary school 1st, 2nd, and 3rd grade students, and teachers about mathematics. In this qualitative study, a basic qualitative research method was used. The study group consisted of 26 children attending kindergarten, 69 students attending primary school, and 13 teachers. The data of the study were obtained through semi-structured interview forms, and were analysed using descriptive analysis. As a result of the research; most of the children attending kindergarten expressed mathematics as number, operation, lesson, and homework; most of the primary school students expressed mathematics as number/counting, operation, lesson, calculation, and all of life/indispensable/everything. Most teachers defined mathematics as all life/indispensable/everything, number, reasoning skills, and logical thinking. While most of the children in the study group stated that they use mathematics at school, at home, in shopping, and in all areas/everywhere in life, almost all of the teachers stated that they use mathematics in all areas/everywhere in life. While children generally stated that they use mathematics at home, at school, and while doing activities/homework/lessons, teachers stated that they use mathematics in all areas of life, at all times, and with the existence of human life. It was emphasised that most of the children stated that mathematics is mostly used in the teaching profession, while most of the teachers stated that it is used in engineering, all professions, teaching, astronomy, and space sciences.
