The data collection instruments were questionnaires and observations. While the data analysis technique is quantitative descriptive analysis. This research resulted in a product of an Educational Game Tool Kado Pintar and a Module. Media expert rated EGT Kado Pintar as "very feasible" with an average score of 4.00, while material expert rated it "fairly feasible" with an average score of 3.00. Parents gave an average score of 3.7 which means "very practical". The results of the small group test was in the "fairly effective" criteria with a percentage of 50%. In the field test, the control group got a percentage of 33.33%, the category "fairly effective," while the experimental group got a percentage of 80% or "very effective". These results indicate that EGT Kado Pintar has a significant influence and it is "feasible, practical, and very effective," to introduce number symbols to early childhood children aged 5-6 years in Cimpar, Laci-Carep Village.
