Cognitive development in early childhood is a crucial foundation for later academic achievement and overall intellectual growth. This study, conducted at TK Ma’arif NU 1 Taman Cari in East Lampung, Indonesia, examined the effectiveness of puzzle-based learning in enhancing cognitive abilities among children aged 5–6 years. Using a Classroom Action Research (CAR) design implemented over two cycles, the intervention aimed to strengthen children’s understanding of fundamental concepts such as shapes, colors, sizes, and patterns. The findings showed a significant improvement in children’s abilities to classify, sequence, and solve problems, meeting and surpassing expected developmental standards. These results highlight puzzle-based learning as an effective and developmentally appropriate strategy for promoting cognitive growth in early learners. Beyond the local context, the study underscores the broader potential of play-based and interactive learning approaches in early childhood education.
