This study aimed to investigate how some teachers talk to students in grade 4-6 about fiction, more specifically, how the teachers in their reading aloud teaching enable students to develop imaginary worlds through conversation. The material was analyzed based on Langer’s (2005) theory about imaginary worlds. Two questions were formulated to answer the study’s aim: How do some teachers plan their conversations about fiction in reading aloud teaching? Moreover, how do teachers’ conversations about fiction vary in reading aloud teaching? The results showed that all teachers plan their conversations about fiction in the reading aloud teaching in different ways. Three of the teachers plan their conversations by reading the fictionin advance to get acquainted with the story and the characters. One teacher plans her conversations about fiction after reading aloud. The result also showed that all teachers vary their conversations about fiction in reading aloudin different ways, such as text extracts from chapters, work with illustrations, book conversations, and keeping the book secret from the students so that they can imagine what the characters and the environment can look like. Finally, the result showed that through the teachers’ conversations, the students were given opportunities to build imaginary worlds and an increased understanding of the text.
