The purpose of this study is to see how some teachers in primary school creates and adapts their mathematics teaching for students with special mathematical abilities. It also aims to identify opportunities and challenges that teachers see in creating a teaching adapted to these students. In this study, qualitative interviews has been done to collect data. The interviews were conducted with five teachers who all are active in the primary school. The study results show that there is great variation in how the interviewed teachers create their mathematics teaching for students with special mathematical abilities. The use of mathematics book proved to be significant for how this adaptation took place. The result also shows that the teachers’ explanations for the choice of the adaptations that they make in teaching vary. Some of the teachers stressed that the teaching they were carrying made it possible for adaptation in the normal teaching while others stressed that they made adjustments to fit the current student best. The result showed two challenges that many of the teachers saw in the creation of a teaching adapted for students with special mathematical abilities. These challenges were time and group.
