Abstract: The article is related to the problem of studying Russian grammar during lessons of Russian as a foreign language. The relevance of the topic is due to the fact that the proper presentation of the didactic material leads to successful mastering of Russian grammar. Great difficulties in understanding are caused by The Adjective, which, as a rule, differs or is rarely used in foreigner's native languages. Practice shows that foreigners use only those lexical items which by association exist in their mother tongues. The goal of the research is to frame and approve the methods of presentation of didactic material contributing to successful digestion of the studied theme. The methodology of the research is based on analysis and observation, which: let the author distinguish the typical mistakes made by the students in the process of building the speech patterns. Conclusions: 1. In the process of studying the topic: The Adjective. The first stage includes studying the definition of The Adjective, what questions does it answer, its gender. The second stage - is studying the endings of The Adjective depending on the gender. The third stage - is coordination of The Adjective with The Nouns. Only after reinforcement of studied material, the studying of cases of The Adjective can be started. 2. The teacher must keep in mind that the teacher should use elementary words in the process of explaining the grammatical material during the first stage of studying. It is necessary to pronounce words clearly, slowly, not to use a great number of linguistic terms which cause difficulties in perception of the Russian language among the students of non-linguistic specialties.
