The study was primarily concerned with the utilization of supplemental worksheet in teaching mathematics 7. Specifically, the study sought to answer the following questions: (1) What is the level of acceptability of the supplemental worksheet in terms of content with regards to objectives, analysis, activities and assessment; (2) What is the level of acceptability of the supplemental worksheet in terms of characteristics with regards to accuracy of materials, appropriateness of material, clarity of material and usability of material; (3) What is the level of the student?s mathematical performance in terms of pre-test and post-test; (4) Is there a significant difference on the student?s mathematical performance in terms of pre-test and post-test; (5) Is there a significant effect of using supplemental worksheet to the student?s mathematical performance. Findings revealed the following: (1) The majority of teachers who evaluated the supplementary worksheet found its contents which are objectives, analysis, activities and assessments to be highly acceptable. (2) Most of teachers who evaluated the supplementary worksheet found its characteristics which are accuracy, appropriateness, clarity and usability to be highly acceptable. (4) There is a significant difference in the student?s mathematical performance in terms of pre-test and post-test. This mean that the mathematical performance of the students were improved after the use of supplemental worksheet, (5) It was also found out that there is no significant effect of using supplemental worksheet to the student?s mathematical performance On the basis of the foregoing findings and conclusion of the study, the following recommendations are offered: (1) The officials of the Department of Education may issue memorandum that will encourage teachers to develop supplemental worksheet as an intervention material to help the left - behind learners and maximize the teachers? potential in making more effective learning materials. (2) School heads and master teachers can include the making and implementation of more supplemental worksheet that uses a concept attainment strategy. (3) Teacher of asynchronous sessions may use these supplementary materials as a script in the teacher made video lesson. (4) The supplemental worksheet can be used by the learners at their own pace and time. They can enhance their knowledge and skills of their least ? mastered competencies by using the developed intervention material (5) Future researcher may use the workbook in a larger number of respondents. They can also use the strategy in other mathematical topics and lessons. Future researcher may also use this study as their guide or reference for follow up and future studies.
