Learning is the essential part of one's growth and there is no doubt that forging a good habit is of great importance both for study and life. So some people think it is good for children to start their study as early as possible and devote themselves in it.However, letting children follow their natures and spend most of time playing with friends or in nature.Playing is the nature of children and it can actually benefit children's learning.There are a lot of things one can learn from playing. Playing enable children inspire their cognitive, responsive and operative ability. Lego has its prestige of developing children's brains.By playing Lego, children's imagination is cultivated and also the operative ability is improved which are significant in learning.Children who spent most time playing, a research shows, perform better than those spent plenty of time on studying. Moreover, playing can assist children forge their characteristics like how to be a good team player, how to get well with others and so on. Children usually play as a team which means they need to learn cooperate with others.In a football competition, it is hard to secure winning unless all the player work together very well.If one player is egocentric and always want to shine, he may let his team lose the chance to win. Next time,when he face the same situation,he will know how to work together with others. That characteristic helps students do well in group study and future life.Of course, if children spend overtime on playing, his mental and physical health will be destroyed, let alone his study. For example, being addicted to computer games steals the time of study and rest.So it is vital for children have self-discipline on playing.Based on what I have discussed, even though spending much time on playing has potential damage on children, as long as control it rightly, it is still the better choice in front of burying children in books most of time.
