<![CDATA[This research was motivated by the low ability of children aged 5–6 years to recognize number symbols at TK Pertiwi 14.06.14 Ampih, Buluspesantren District, Kebumen Regency. The study aimed to improve children’s ability to recognize number symbols through the learning by doing method. This research used Classroom Action Research (CAR) based on the Kemmis and Taggart model, consisting of planning, action, observation, and reflection stages. The study was conducted in two cycles involving 16 children in group B. Data were collected through observation and documentation, while data analysis used descriptive quantitative and qualitative techniques. The results showed that the learning by doing method was able to improve children’s ability to recognize number symbols. The percentage of success increased from 35% in the pre-cycle to 62% in cycle I and reached 87% in cycle II. Children became more active, confident, and capable of mentioning, matching, and arranging number symbols correctly. Therefore, the learning by doing method is effective in improving number symbol recognition skills in early childhood.
