This study was focused on the evaluation of the relationship of learning strategies of intermediate pupils with their acquisition of grammatical skills during the online learning modality. The research design used in this study was the descriptive correlation method of research.  The respondents were the ninety (90) Grade 5 students. Further, the research findings revealed that the high or low level of grammatical skills is just as likely to occur with the high frequency of use of learning strategies as it is with the low frequency of use of learning strategies. Moreover, the findings proved the frequency of utilizing the learning strategies does not relate significantly with the grammatical skills of the pupils and that there was a significant relationship that exists between memory strategy and the grammatical skills, thus it was recommended that frequent utilization of learning strategies may be considered to improve students’ grammatical skills.
