This study aims to identify and analyze the learning obstacles faced by first-grade elementary school students in mathematics learning using CPA (Concrete-Pictorial-Abstract) approach-based textbooks. The CPA approach is considered effective in helping students understand mathematical concepts gradually, starting from the concrete stage, moving to the pictorial stage, and finally reaching the abstract stage. However, in its implementation, various challenges and difficulties may still be encountered by both students and teachers. This research will be conducted randomly in several Grade 1 classes at Sekolah Lentera Harapan, which are confirmed to be using CPA-approach, namely the Matematika Juara book that adopts the Singapore curriculum. Through qualitative methods and direct observation, this study seeks to gain a deep understanding of the types of learning obstacles experienced by students and to explore the factors that influence the effectiveness of CPA-approach in teaching and learning activities.The expected outcomes of this research include several key aspects. First, documentation of the types of learning obstacles found among students when using CPA-based textbooks. Second, the formulation of more effective teaching strategies to overcome the identified learning obstacles, thereby improving students' understanding of mathematics. Third, a practical guide for teachers on how to optimally implement CPA-based books in Grade 1 classrooms. It is hoped that this study will make a significant contribution to the development of curriculum and mathematics teaching methods, particularly in Grade 1, by promoting more optimal use of the CPA approach.
