This study aimed to examine the effect of the Pink Tower learning media on the ability to recognize object sizes and the concentration of children aged 4–5 years. The research employed a quasi-experimental method using a pretest–posttest control group design involving 20 children who were divided equally into an experimental group and a control group. The findings revealed that the experimental group demonstrated significantly greater improvement than the control group. These results indicate that the Pink Tower learning media has a positive and significant effect on enhancing children's ability to recognize object sizes and improving their concentration during learning activities. Therefore, the Pink Tower can serve as an effective Montessori-based educational medium to support cognitive development and learning readiness among early childhood learners.
