Early childhood mathematics is an important foundation for later learning, yet initial observation at TK Kasih Ibu showed that many Group B children had difficulty recognizing and representing number symbols. Previous studies have shown the potential of QR-code media for early childhood learning, but limited research has combined QR-code exploration, a scavenger hunt activity, and animated demonstrations of number formation. This study aimed to examine the effect of QR Code Scavenger Hunt media on children’s number-symbol recognition. A pre-experimental one-group pretest-posttest design was conducted with 28 Group B children. Data were collected through pretest and posttest assessments and analyzed using descriptive statistics and the Wilcoxon signed-rank test. The mean score increased from 69.63 to 87.79, with an average gain of 18.16 points. The proportion of children achieving the highest score category increased from 35.7% to 92.9%. The test showed a significant difference between pretest and posttest scores (p < 0.001). The novelty lies in integrating physical exploration, QR-code access, animated visualization of number formation, and follow-up learning activities. The findings indicate a significant improvement in children’s number symbols recognition following the implementation of QR Code Scavenger Hunt media among Group B children.
