Primary school religious education is important and understudied in modern educational practice. Classes on religious education are used to impart knowledge to pupils about the world’s main religions. Knowledge about specific religions, or how to collaborate with representatives of different religions, is mostly absent. Unfortunately, teachers of religious education often do not use their classes as a tool for their students’ moral and spiritual development. It is also one of the problems for Swedish schools and it has to be solved because Sweden is a very multicultural country with representatives of many religions; and one of the tasks of modern schools is to show how to be tolerant of others. This research aims to highlight problems and develop ways of teaching religious education in primary schools through theoretical literature analysis on the research topic. Also, we provide didactic exercises which teachers can use during religion lessons to diversify them and make it more accessible to students.
