This study aims to determine the effect of currency-themed busy book media on the understanding of currency value in students with intellectual disabilities at SLB Insan Tiara Bangsa. This study used a quantitative approach with a one-group pretest-posttest experimental design. The subjects consisted of five grade V students with mild intellectual disabilities, selected using a total sampling technique. Data were collected through an objective test that had been validated by an expert before and after the treatment. The data were analyzed using the Wilcoxon Signed Rank Test in SPSS version 27. The results showed a significant increase in students' scores, from an average of 64.80 in the pretest to 88.80 in the posttest with a significance value of p=0.042 (p < 0.05). The use of this busy book media proved to help students learn visually and practically, make the concept of money more concrete, and increase their learning focus. In conclusion, the currency-themed busy book media has a positive and significant effect on students' understanding of currency value, making it highly suitable for functional academic learning.
