Independent reading is given lower priority in today's teaching. School activities prioritize students' reading ability to a greater extent than student motivation. Both the curriculum and various mapping materials focus more on students' reading development than on students finding reading pleasurable. The purpose of the study is therefore to explore how students' interest in reading is taken advantage of in grades 1-3 and to make visible how teachers work to promote students' fiction reading. The literature on which the study is based has been found by means of information search via various search services. The material that has been analyzed is eight scientific articles, one doctoral dissertation, one report and two research overviews. These are a mixture of international and national studies. The results of the study showed that there are several factors that affect students' motivation. The study places great emphasis on the factors that have a positive effect; internal motivation, strategies to increase students' interest, the teacher's role in the work with reading and the relationship between student and teacher. Extrinsic motivation is also discussed in relation to intrinsic motivation.
