This study aims to develop a mathematics education program supported by stories for 48-60-month-old children attending pre-school education institutions and examine its effect on children's early mathematics skills. The study group consists of 48-60-month-old-children who continue pre-school education in an independent kindergarten affiliated with the Ministry of National Education in Usak province, in 2020-2021. The study was carried out with 33 children, 18 in the experimental and 15 in the control group. A pretest-posttest quasi-experimental design with a control group was used in the study. Test of Early Mathematics Ability-3 (TEMA-3), developed by Ginsburg and Barody, was used to collect data. The test's adaptation, validity, and reliability to 48-60-month-old Turkish children had been conducted by Seker (2013). Regarding data collection, TEMA-3 was administered as a pre-test to the experimental and control group students before implementing the program. After the pre-test, the "Mathematics Education Program Supported by Stories" was instructed to the experimental group three (3) days a week for eight (8) weeks. During the implementation, "Mathematics Education Program Supported by Stories" was instructed to the children in the experimental group by the researcher; the daily education flow specified in the 2013 Pre-School Education Program was continued for the control group children. The data obtained from the research were analyzed with the SPSS statistical program. Independent and dependent t-tests were used to test the difference between the pre-test and post-test between and within groups. Based on the findings obtained from the analyzes, there was no significant difference between the pre-test scores. However, there was a significant difference between the post-test scores in favor of the experimental group. It was concluded that the mathematics education program supported by stories effectively improved children's mathematics skills.
