Abstract

This study aimed to develop a Montessori-based teaching and learning aid to help first-grade students to understand better the concepts of addition and subtraction. The research employed a
Research and Development (R&D) method with the Borg and Gall model, adapted to six stages: research and data collection, planning, initial product development, preliminary field testing,
product revision, and main field testing. Product validation was conducted by experts in content, media, and pedagogy, showing that the aid being developed was highly valid for classroom use.
Field trials at MI Al-Maarif 02 Singosari, using a pre-test and post-test design, demonstrated a significant improvement in students' arithmetic skills, with average scores increasing from 70.34
to 94.83. The N-gain analysis showed a score of 0.78, indicating high effectiveness of the learning tool in enhancing students' abilities. This study suggested that the Montessori-based teaching and learning aid significantly improved students' understanding of basic mathematical concepts in a fun and comprehensible way.
