This thesis is focused on pictograms used in Croatian language classes at early stages of education. The paper deals with pictographic language and its different types, historical background of pictograms, and pictogram design. It studies the general use of pictograms in classes, as well as their use in Croatian language classes. The research that was conducted for this thesis had a goal of exploring the primary students’ knowledge of pictograms in Croatian language classes. The aim was to find out how much were the younger learners acquainted with pictograms, and their ability to differentiate between them. The research participants were the students of first, second, third, and fourth grade of Vladimir Nazor primary school, in addition to local schools of Donja Motičina and Seona. There were 65 participants made up of both genders (M=31, F=34). The research was composed of 19 students of first grade, 16 second grade, 12 third grade, and 18 fourth grade students. The respondents were obliged to answer questions about gender, the grade they attend, and state their knowledge on the pictograms used in Croatian language classes. The last seven questions required the names of the offered pictograms. A questionnaire made up of fourteen questions was produced for the sake of the research.
