The best way for parents to teach their children is to play with them. Since indoor and outdoor play is a child's opportunity to explore his new world, it is very important for his growth. To help their children develop cognitive, social and psychological skills, parents should actively participate in their children's playtime. The first step parents need to take is to give the child enough space to play. Sufficient play space will give way to paths, ramps, bridges, hills, etc. (Strickland par. 3). Since the child will have more space to move, his body will engage in actions, which is important for him to learn how his mind cooperates with his body. Provide tools such as plastic shovels, buckets of sand or wooden blocks to encourage him to build anything he wants. Things like sand, water, building blocks and boxes are movable. Since they are mobile, they are also changeable; he can calculate in his head what needs to go where (Strickland par. 1). Balancing, lifting and carrying will help develop his cognitive skills because he will use his mind to complete his project just as he imagines it (Strickland par. 2). Movements and strategies accompanied by outdoor projects will improve his motor coordination and refine his timing skills (Muller par. 38). Dr. Katheleen Alfano, director of research at Fisher Price, states that “there has been a lot of research recently on the link between play and movement and intellectual development” (Muller par. 37). Of course, the parents' role in this activity is to monitor the child's play, but not to linger or intervene. Parents may feel pressured to correct the child's construction method, but it is essential that the child…… half of paper……k. There is no time commitment and the child still enjoys the moment of play (Bush par. 4). There are many things to do outside that help define the child's character: reading outside (Bush par. 8), looking at the sky (Bush par. 9), listening to the sounds of animals (Bush par. 10), looking at the many insects and much more. When a child sees an eccentric insect, his reaction will represent its character and personality. It also helps him explore his feelings (Bush par. 7). Allowing aggressive play and scheduling time to see the world together are ways parents can actively participate in their children's playtime. The famous author Dr. Seuss thinks that "adults are obsolete children." However, parents sometimes need to put adulthood aside and actively participate in their child's playtime to help him develop cognitive, social and psychological skills..
