Mastery of early numeracy skills is essential for progressing to higher-order mathematical thinking. To excel in Mathematics, learners must demonstrate proficiency in number sense, pattern recognition, and problem-solving. These competencies form the cornerstone of mathematical understanding and are vital for fostering students' ability to analyze and think critically. This study dealt with the development and validation of instructional skill book in grade 1 Mathematics in Lupi District, Camarines Sur, school year 2022-2023. It determined the following: 1) proficiency level of grade 1 learners in Mathematics along number sense, number seriation, and problem solving; 2) significant differences in numeracy level among learning areas and among learning groups; 3) design of the developed skill book for grade 1 learners in Mathematics along expected learning outcomes, learning content, and learning activities; 4) curricular validity of the skill book in terms of alignment of curriculum objectives, meeting individual needs, and diversity of drills/ exercise for learning activities; and 5) implication to educational management. The result of the study would be a great help to the grade 1 learners, teachers, and curriculum makers to consider the use of supplementary materials in enhancing learners’ numeracy skills that will encourage and motivate learners to learn more and develop their skills along number sense, number seriation, and problem solving.
