This research aims to determine the effect of using flashcard media on the beginning reading abilities of children aged 5-6 years at the Sahabat Rina Medan Kindergarten. This research uses an experimental method approach (Quasi-experiment design) in the form of The One Group Pretest-Posttest Design. The population in this study were all students aged 5-6 years in class B2 with a sample size of 20 children at the Sahabat Rina Medan Kindergarten.

Based on data analysis through non-parametric hypothesis testing, the SPSS 25 statistical test was obtained, namely 0.000. Therefore, it can be concluded that the use of flashcard media has a significant influence on the beginning reading abilities of children aged 5-6 years at Sahabat Rina Kindergarten.
