The article is devoted to the study of a pressing issue in linguodidactics -the development and implementation of a methodology for overcoming phonetic, graphic, and orthographic difficulties in the process of teaching Ukrainian as a foreign language (UFL) to preschool children (4-6 years old).The main topic of the research covers the analysis of specific language barriers that arise in an allophone environment and the search for optimal ways to minimize them through game and interactive technologies.The problem of the research is determined by the need to overcome linguistic interference, which is most clearly manifested at the stage of a child's transition from the initial level of language proficiency (A1) to the basic level (A2).Special attention is paid to the articulation of complex sounds and the assimilation of specific letter combinations that are often absent in the phonological system of the language of the child's country of residence.The aim of the article is to provide a theoretical substantiation and practical demonstration of the effectiveness of a comprehensive approach to teaching UFL based on the third part of the textbook My Friends (Difficulties in Pronunciation and Writing).The work analyzes the structure of thematic lessons aimed at correcting the pronunciation of affricates [dzh], [dz], the sound [shch], as well as studying jotted phonemes and the rules for using the soft sign and apostrophe.The research methodology is based on the communicative-game approach, which corresponds to the psychophysiological characteristics of preschool children.The generalized results of the study indicate that the use of multimedia content (songs, poems, video materials) in combination with a clear algorithm of exercises Listen -Repeat -Find -Say significantly increases the level of speech competence of preschoolers.Practical testing on the material of the lesson The Room demonstrated that the integration of grammatical material into the lexical context promotes the natural assimilation of language norms without excessive cognitive load on the child.The proposed methodology provides the formation of stable articulatory skills and lays the foundation for successful mastery of Ukrainian writing.
