General Background: Fine motor development is an important aspect of early childhood development, particularly for children aged 4–5 years who require stimulation involving small muscles and eye-hand coordination. Specific Background: At TK Islam Al-Ikhsan, several children experienced difficulties holding pencils, opening bottle caps, grasping objects, and performing activities requiring fine motor control. Knowledge Gap: The study addresses the need for a more varied classroom activity by applying collage with simple materials to the observed fine motor difficulties in Group A2. Aims: This study aims to examine the application of collage activities and the improvement of fine motor skills among 4- to 5-year-old children. Results: Using classroom action research conducted in two cycles, data were collected through observation and documentation. Achievement increased from 12.50% in the pre-cycle to 37.50% in Cycle I and 87.50% in Cycle II. The activities used origami paper pieces, corn kernels, and Dacron attached to prepared picture patterns, with improvements including enlarged patterns and easier-to-handle materials in Cycle II. Novelty: The study applies simple collage materials and step-by-step classroom improvements to train eye-hand coordination, grasping, and object-picking skills in the specific context of Group A2. Implications: The findings indicate that structured collage activities using accessible materials can be used as a classroom activity to provide repeated stimulation for fine motor development in early childhood. Key Findings Highlights Achievement increased from 12.50% before the intervention to 87.50% after two cycles. Enlarged picture patterns and easier-to-handle materials addressed difficulties observed during the first cycle. Children showed better coordination, grasping, object-picking, focus, and independence during the second cycle.
