Over time, the literacy rate enrollment rates and learning outcomes in Sindh have remained static, and despite efforts and pouring a lot of domestic and foreign funds, no visible improvement either in the state of schools has been observed, or any improvements in the enrollment or learning outcomes have been noticed. One key element that is mostly ignored is to make teaching-learning interesting and child-centred in an informal way by introducing co-curricular activities. Co–curricular activities are physical activities and programs that are informal ways of learning and help create a healthy and active learning process at school. This paper highlights the importance of co-curricular activities on child development and its effects on adulthood. Holistic child development is the best way to develop healthy, economically sound nations. Studies have shown that healthy and economically strong countries have strong early childhood education systems. This independent study has examined the impact of co-curricular activities on the increase in enrollment and learning outcomes at primary schools in the Layari district of Karachi by identifying schools with playgrounds. These include physical and mental activities like outdoor and indoor plays, mental activities, and exercises.
