Abstract

Place value understanding is essential for developing foundational numeracy skills among elementary learners. This study investigates the effectiveness of place value charts and concrete manipulatives in improving Grade 2 learners’ understanding of three-digit numbers at Ambaguio Central School. Employing a quantitative approach with a one-group pretest–posttest design, the study evaluates learners’ performance before and after implementing structured instructional activities using base-ten blocks, bundled sticks, and place value charts. Data will be analyzed using descriptive statistics and a paired-samples t-test to determine improvements in mathematical understanding. The study aims to provide evidence on the potential of visual and hands-on instructional strategies to address place value difficulties. Findings are expected to inform effective instructional practices and strengthen foundational numeracy competencies in elementary Mathematics education.
