Learning Management Systems (LMS) are becoming increasingly important in today's educational system. The study aimed to determine students' insights and the advantages and disadvantages of using a learning management system in mathematics class. The participants in the study were ten (10) students who were carefully chosen for the study. Vygotsky's sociocultural and e-learning theories were the foundation for this study. A single descriptive case study design was utilized in this study, and thematic (Braun & Clarke, 2006) data analysis was used to analyze the data acquired through a semi-structured questionnaire in a google form and a virtual focus-group conversation. The results demonstrated the following insights: feasible learning tools, adequate learning resources, and a depository of learning. The antecedent of knowledge and self-driven growth are advantages of using a learning management system in a mathematics class, then the disadvantages include unpredictable learning occurrences and internet service disruption. The findings of this study enable the academic community to develop additional online techniques and materials that can enhance learning outcomes and engage students even during a pandemic.
