This research aims to improve early childhood cognitive abilities through the application of brain gym activities at ABA Kartini Kindergarten, Binjai Kota District. Based on the results of initial observations, most of the children of group B have low cognitive development, namely 30% have not developed and 40% have begun to develop. This condition shows the need for a learning strategy that is able to stimulate the balance of right and left brain functions so that children can think actively, creatively, and focus. The study used the Kemmis and McTaggart spiral model Class Action Research (PTK) approach with four stages: planning, action, observation, and reflection. The study subjects consisted of 20 children aged 5–6 years (11 boys and 9 girls). Data was collected through observation, interviews, and documentation, then analyzed quantitatively using the percentage of learning completeness and qualitatively through the description of the observation results. The results showed that there was an increase in children's cognitive abilities from pre-cycle by 30%, to 55% in cycle I, and increased again to 90% in cycle II after the application of brain gymnastics activities.
