This article examines the common grammatical errors observed in schoolchildren learning English as a second language. Through a systematic analysis of learner errors, this research aims to identify recurring patterns and challenges in grammatical competence among school-aged English language learners. By shedding light on these typical mistakes, educators can tailor their teaching strategies to address specific areas of difficulty and enhance students' grammatical proficiency. The findings contribute to the ongoing discourse on effective English language teaching methodologies for schoolchildren.
