I have made this study because I want to know what pupils think about mathematics. If they like it or not and if they think it is important for them. I also wondered if I could see any differences in attitudes between ages and why they think as they do. This because I, as a teacher, want my pupils to like mathematics and have a good attitude to mathematics even when they get older. My work is built upon literature and interviews with twenty-four children, between ages seven to eleven. In the literature I have studied which causes that make a difference in attitudes. I have also asked the pupils why they like mathematics or why they don’t like it. The analysis shows that there is a difference between younger and older pupils about their attitudes to mathematics. The younger pupils like it a lot but the interest decreases by age. But almost everyone think it is an important subject in school. Maybe the reason why the older pupils have lost their interest for the subject is because the mathematics has become too much theoretical and not so varying like the mathematics subject is at the lower class.
