Planning activities for pre-school children requires a clear understanding of their developmental needs, interests, and learning capacities. At the pre-school stage, children are in a crucial period of rapid physical, cognitive, social, emotional, and language development. Therefore, the principles guiding activity planning must be child-centered, developmentally appropriate, and flexible enough to accommodate individual differences among children. One of the most important principles is developmental appropriateness. Activities should be planned according to the age, abilities, and readiness of pre-school children. Tasks that are too complex can lead to frustration, while overly simple activities may result in boredom. Properly planned activities help children gradually develop skills such as motor coordination, language expression, problem-solving, and social interaction. Understanding developmental milestones enables teachers to design activities that support holistic growth rather than focusing on isolated skills. Another key principle is learning through play. Play is the natural medium through which young children explore their environment
