{"abstract":"This study aimed to assess the numeracy skills of Grade 2 students and examine the relationship between their demographic characteristics and their numeracy proficiency. A total of 150 students participated, and data were collected regarding their family income level, parent education, and parental occupation. The study found that the majority of students came from families with moderate income levels, and their parents had varying educational backgrounds, with a significant portion having at least a high school education. The students' numeracy proficiency was analyzed, revealing that most scored in the 41%-60% range, indicating moderate numeracy skills. Statistical analysis showed a significant positive correlation between parental education (r = 0.762) and parental occupation (r = 0.605) with the students' numeracy skills, while family income level did not exhibit a significant correlation. Based on these findings, the study recommends the development of targeted instructional drill materials, parent education programs, and numeracy support initiatives to enhance students' numeracy skills. Additionally, it suggests that professional development for teachers and increased parental involvement are essential to improving the numeracy proficiency of Grade 2 students.","abstract_source":"original","authors":["Jerahmeel Tumaob","Charitte Parazo"],"date":"2025-08-20","doi":"10.70838/pemj.450507","id":6202,"issue":5,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"8137b3c770dce92cbf4f4ae2d0e9ce107940e2d13aae0f6a778bb28677b1aa9d","schema":"scimatic-article/1","title":"Assessing the Numeracy Skills of Grade 2 Students: Basis for Instructional Drill Material Development Program","volume":45}
