The article is devoted to the issue of the accessibility of understanding polycode narratives for students in primary grades. It is shown that narrative texts encountered in the experience of younger schoolchildren can be presented both in the traditional linguistic (printed) form and as a visual narrative (comics, graphic stories). The peculiarities of perception and understanding of visual narrative are related to the configuration of visual information, which is important for the selection of polycode texts as a didactic tool. Such texts are especially effective for the development of the textual competence of elementary schoolchildren at the initial stage of education but can be integrated into educational material during the entire period of study at the stage of primary general education. According to the survey the success of primary school students in understanding a vector-type polycode narrative text was found. Gender differences while working with various types of narratives were revealed: girls demonstrate great success in working with polycode narratives and boys - with text narratives.
