Abstract
This article examines the scientific and practical foundations of communicative grammar as they relate to the process of writing. This study is relevant because previous research has not sufficiently addressed the methodological aspects of developing communicative grammatical competence in written Kazakh, leaving both theoretical understanding and classroom practice underexplored. The purpose of this article is to develop recommendations for mastering grammatical skills and using communicative methods of teaching the Kazakh language in the process of writing. The results of the study made it possible to claim that the formation of aspects of grammatical skills in the process of writing is considered as an indivisible part of all components of the formation of speech activity. The practical significance of this study lies in the development of a structured set of tasks designed to improve students'writing skills through the use of communicative grammar. Grounded in the principles of communicative language teaching, task-based learning, and functional grammar, these tasks offer a pedagogically sound approach to language instruction. The materials developed in this research can be effectively utilized by educators in designing lessons for both schoolchildren and university students. These resources are particularly relevant for educational institutions across the Republic of Kazakhstan, providing teachers with practical tools to support language development in a communicative and contextually meaningful way.
