identify deficiencies in children's development. While there are many types of play children engage in that all contribute to development, it has been emphasized that free, spontaneous play—the kind that occurs on playgrounds—is the most beneficial type of play. Recess is key in the development of children. Studies have shown that recess plays a large role in of how children develop their social skills. During recess, children usually play games involving teamwork. On the playground, children use many leadership skills – they educate other children about games to play, take turns, and learn to resolve conflicts while playing these games. The leadership skills promoted throughout recess are how children are able to continue to play the games. Along with developing social skills, recess helps with the development of children's brains. Recess gives the children's brains a chance to “regroup” after a long day of class. Also, the physical activity actually leads to the development of the brain. Brain research has shown a relationship between physical activity and the development of the human brain. Another study supports these findings from the brain research. A school system that dedicated one third of their school day to nonacademic activities such as recess, physical education, etc., led to improved attitudes and fitness, and improved test scores despite spending less time in the classroom. Social development Problem solving is an integral part in child development and free play allows for children to learn to problem solve on their own. Teachers and caregivers can scaffold problem solving through modeling or assisting when a confrontation occurs. Although play should involve adults, adults or caregivers should not control the play because when adults control the play, the children can lose their creativity, leadership, and group skills. Adults should let children create and follow agreed upon rules and only intervene if a serious conflict arises. Problem solving encourages children to compromise and cooperate with each other. The conflict resolution process helps children to attain a vast range of social and emotional skills such as empathy, flexibility, self-awareness, and self-regulation. This vast range or capabilities is often referred to as "emotional intelligence" and is essential to building and maintaining relationships in adult life. Teachers can also view recess as a time to observe children's social and cognitive development skills and be able to develop different activities in the classroom that reflect the children's interests and development.
