ENThe development of metaphorical thinking occupies a significant place in the process of holistic (total) education of the personality. The development of children's metaphorical thinking is a current issue that opens up new opportunities for scientific and practical researches in the field of cognitive potential of childhood; therefore it is especially important that this education begins as early as possible in both formal and informal environments. The aim of the study is to analyze the means of expression of metaphorical thinking in primary school Lithuanian language textbooks. Having analyzed the literature of Lithuanian and foreign authors and the qualitative analysis of the content of primary school Lithuanian language textbooks, can be stated that the development of metaphorical thinking is an important criterion in the education of primary schoolers. The development of metaphorical thinking in primary classes takes place consistently and systematically – new words / phrases are presented; figurative words/phrases; thoughts that can be expressed indirectly; international words are used. The means of artistic expression, which are abundant in primary school textbooks, are one of the forms of expression of metaphorical thinking. In conclusion, it can be stated that the analyzed Lithuanian language textbooks for primary classes correspond to the 2022 updated concept of general education programs. Keywords: metaphorical thinking, primary schoolers, textbooks. [From the publication]
