Developing grammatical competence in primary school English lessons via CLIL

Innovative approaches to grammar instruction in early language education are gaining attention as educators seek more engaging, content-rich alternatives to traditional methods. This study examines how the CLIL methodology supports such development in young learners. As there are the limitations of traditional grammar teaching methods which are often characterized by decontextualized drills and rule memorization the study offers a more engaging and communicative approach grounded in meaningful content and learner participation. CLIL, as an educational framework, allows young learners to acquire grammatical competence organically by embedding grammar within subject-based activities across various disciplines from the school curriculum. The article outlines various strategies including storytelling, project-based learning, interactive games, visual grammar aids, and digital tools. These techniques foster a deeper understanding of grammatical structures while supporting cognitive development, emotional engagement, and maintaining learner motivation. Special emphasis is placed on scaffolding, multimodal input, and the developmental needs of primary school students. The study draws from qualitative research, content analysis, and pedagogical modeling to demonstrate how grammar can be internalized through real-life communication contexts and integrated learning scenarios. Practical classroom examples such as sentence-building games, storytelling with targeted grammar points, and interdisciplinary projects illustrate how CLIL promotes both fluency and accuracy in language use. The article also examines the role of the 4Cs Framework (Content, Communication, Cognition, Culture) in shaping effective grammar instruction. Ultimately, CLIL-based grammar teaching is shown to enhance students' communicative competence, align language acquisition with natural learning processes, and support long-term educational outcomes. This approach contributes to a more holistic, inclusive, and effective model of early language education by emphasizing interaction, creativity, learner-centeredness, and relevance to learners' everyday experiences and interests.
