The work on enriching the vocabulary of students with vocabulary is of great importance for the formation of writing skills, for the prevention of spelling errors in the written speech of children, because it develops in schoolchildren a versatile attention to the word, a responsible attitude towards it. The solution of the main task of vocabulary work - the enrichment of the active vocabulary of students - is facilitated by the systematic consolidation of newly learned words. The main condition for the consolidation of new words is their repetition, systematic use in coherent speech. New words in each lesson of the Russian language should be given in a strictly limited number, which makes it possible to introduce a planned and systematic presentation of the material, to instill in the student a responsible attitude to vocabulary work. Rationing increases the responsibility of the teacher himself for the formulation of vocabulary work.
