Mathematics is an abstract subject that is often perceived as difficult and thought-provoking. People are considered to have strong feelings about the subject, either it is something you like, or not. As a result, the teacher has a great responsibility in working with the students' attitude towards the mathematics subject at a young age. This study is conducted in order to create an understanding of how third-grade teachers work to promote good attitudes among students in the subject mathematics, and which factors affect teachers who work with this. The subject has been investigated through the use of a qualitative method in the form of interviews. The study is based on the framework factor theory, which explains how teachers' work is affected by framework factors to which school activities relate to. The results of the study have been worked with and analyzed in relation to the framework factor theory and previous research studies. As a result, similarities and differences were presented among all respondents' working methods to promote good attitudes among their students towards the subject mathematics. It also emerged that the respondents had common opinions that varied teaching is central to the promotion of students' attitudes. They themselves work in different ways with varied teaching, outdoor teaching or laboratory material. The results also showed that the respondents are affected by various factors such as the school's relationship to current finances, time and individuals, which relates to the framework factor theory. The conclusion of this study is that teachers work in different ways in order to create a positive attitude for students towards the subject mathematics, but their work is affected by various factors that the school acts upon.
