Numerous theories have illustrated the role of play in children for their development. According to Jean Piaget, children are actively involved in their environment. The child initiates an activity and gathers the necessary information through the exploration of his environment. This is where Piaget introduces the diagram. Schema is essentially how knowledge is structured or categorized in a child's mind. According to Piaget (2006), the schema is formed through the process of assimilation (the child perceives the environment according to his own way) and accommodation (reinforcement of knowledge that the child already knows). Piaget suggested that children develop in 3 stages: mastery stage/training play, play stage/symbolic play, and play stage/games with rules (MCI, Child Development Module, Chapter IV, 2013 ). Play is important for the holistic development of a child which includes physical (gross and fine motor development), intellectual (analyzing, understanding, concentration), language (communicating with others such as speech), emotional (emotions, identity) and social (relationship with others) (MCI, Child Development Module, chapter I, 2013). A holistic approach centers around the child and views each child as an individual. All children go through each area of ​​development and learn different things at different stages of growth like crawling, walking, etc. All are interrelated and if one aspect is not met, the child will have delays or difficulty reaching their milestones (Sheridan, 2002). The game must always be initiated by the child, otherwise the child will not enjoy the game and will not show creativity. According to Vygotsky's theory (1999), cognitive development was directly linked to play. Vygotsky (1999, p10), "distinguishes two l...... middle of paper ......r where the parent must be aware of the level of cognitive development in order to know what type or level of scaffolding can be given to the child. In short, “the role of the adult is to provide a structure within which children can interact – to provide challenges, pose problems to solve, encourage children to test ideas and, perhaps most importantly , open up personal learning strategies for children” (Moyles, 2005, p123). An adult should always observe a child in everything he does. Observation will provide us with important information about the child's development and what more can be done during play (Sheridan, 2002). To understand a child in depth, it is best for the adult to play or use the materials used by the child. This will allow us to know exactly what a child might feel or experience with this particular toy (Jones, et al.., 2006).
