For the few years, we had been all staying in our homes due to the lockdown and community quarantine policy implemented by the Government, but learning should not halt. The Division of Ilocos Sur had an orientation on preparing learners’ self-learning kits (SLKs) based on the K to 12 most essential learning competencies (MELC) to address quarantine issues. One of the fundamentals of Mathematics that students should know is fractions, however, the competencies in addition and subtraction of fractions were the least mastered as perceived in the Test Item Analysis of Pias Elementary School (ES) during the First Periodic Examination for Grade 6 pupils for School Year (SY) 2021-2022. This study aimed to determine the effectiveness of Digitized SLK in improving the numeracy skills of Grade 6 pupils of Pias ES. Further, it sought to determine (1) the level of the numeracy skills of Grade 6 pupils in Math before the implementation of Digitized SLK, (2) the level of numeracy skills of the Grade 6 pupils in Math after the implementation of Digitized SLK, (3) the rate of pupils with improved performance and, (4) the significant difference between the level of performance of the pupils’ respondents before and after the implementation of the Digitized SLK. 

The study used one group pretest-posttest research design to determine the effectiveness of the Digitized SLK in improving the mathematical skills of the 17 Grade 6 learners composed of seven (7) boys and ten (10) girls. They were presently enrolled learners of Pias Elementary School for SY 2021-2022. A total enumeration of Grade 6 learners was considered as respondents of the study because all learners have difficulties understanding the lesson due to very low-test results. The researcher created a digitized self-learning kit based on the approved self-learning kit of the Schools Division of Ilocos Sur. The learners used their smartphones since all the enrollees in Grade 6 have their smartphones at home based on their Learner Enrollment Survey Form.
