The study aimed to create a Simplified Workbook to improve the performance and retention of Grade 7 learners in Algebra at Solotsolot National High School. It addressed research questions about learner profiles, Algebra performance levels, relationships between profiles and performance, and competencies that were mastered or not. Using descriptive-correlational and descriptive-developmental designs, data was collected through the Test Result and Item Analysis Package (TRIAP) for the second quarter, with analysis using frequency count, percentage, mean, and correlational techniques. The findings showed varied learner profiles in terms of sex, parental education, socio-economic status, and study habits. The performance in Algebra was generally satisfactory, with a grand mean of 27.49, and only the occupation of the mother had a significant relationship with performance. Most Algebra competencies were not mastered, indicating the need for a simplified workbook. The study's conclusions highlighted the need for parental involvement, resource centers, and teacher training to enhance learning outcomes. Recommendations included cooperation between parents and schools to improve discipline and interest in school activities, the use of the Simplified Workbook in Algebra 7, and encouraging active participation in Mathematics-related activities. Additionally, it was suggested that Mathematics teachers attend training sessions to enhance their teaching strategies and consider setting up Mathematics Clubs. Future research could examine other factors affecting mastery of Algebra competencies, such as teaching methodologies, social media exposure, and teacher-related factors.
