This study determined how the mathematical proficiency influence achievement in sequence of Grade 10 students and used the findings as basis in crafting worktext in Sequence, at Anib National High School, Anib Sipocot, Division of Camarines Sur for School year 2024-2025. Specifically, it answered (1) the level of mathematical proficiency of the students; (2) the students’ achievement in sequence; (3) the relationship between mathematical proficiency of students and their achievement in sequence; (4) the influence of students’ mathematical proficiency on their achievement in sequence; (5) the design of the worktext, and (6) the curricular validity of the worktext. The research employed descriptive-correlational and research and development (R&D) methods, involving 80 Grade 10 students from Anib National High School in school year 2024-2025. Data collection tools included teacher made test and evaluation checklist. Statistical tools involved Mean, Standard Deviation, Proficiency Level, Pearson-product Moment Correlation Coefficient, Coefficient of Determination and Weighted Mean. Key findings were (1) the level of mathematical proficiency of the students’ has an overall proficiency level of 39.37; (2) the students’ achievement in sequence have an overall proficiency level of 41.23; (3) the relationship between achievement of students in sequence and mathematical proficiency ranged from r-value of 0.009 to 0.770 and a p-value from 0.000 to 0.936; (4) the degree of influence of students’ achievement in sequence on mathematical proficiency obtained an r2-values of 0.000 to 0.593; (5) the design of the worktext was divided into learning objectives, learning content, learning activities, and learning assessment; and (6) the curricular validity of the worktext obtained an overall average weighted mean of 4.83. The major conclusion were (1) the mathematical proficiency skills of students were in the developing proficiency level; (2) the students demonstrated developing proficiency on achievement in sequence; (3) there was a significant relationship between the mathematical proficiency of students and achievement in sequence across parameters; (4) the mathematical proficiency influence ranged from negligible influence to high influence on the achievement of the grade 10 students in some areas; (5) the worksheet design enhanced the students mathematical proficiency and achievement in sequence, and (6) the overall validity of the worksheet was deemed very highly valid.
