From the perspective of developing children's intelligence, parents should pay special attention when they are four or five years old. Using the right method and mastering the degree of early education will benefit children endlessly. Explain patiently "why". With the change of brain, children urgently need to expand their knowledge and often ask their parents, "Why is this?" In this case, parents should try to explain patiently with their children's language and way of thinking, not too complicated. Children's memory will be further improved while learning knowledge. Cultivate the ability of simple reasoning. You can take children to nature and let them observe animals and plants in detail and ask questions. For example, "Why do birds fly in the sky?" "Why do young trees only grow on the ground?" After returning home, compare the pictures in the book, tell them stories and stimulate their imagination. Practice fine finger movements. Ten fingers are connected to the brain, so the development of the brain can not be separated from the promotion of finger activity. During this time, parents can try to let their children do some simple manual work, such as folding paper planes and clothes, or even just encouraging their children to rub their hands, which is good for brain development. Enrich the game content. Children aged four or five are curious about all kinds of movements and postures. Parents should play games with their children more often, and let them learn to climb, climb and throw through games. In this process, they will feel excited, and this reaction can directly stimulate the brain nerves, which is of great help to children's observation, reaction and judgment. However, Lu Jie reminded parents not to let their children learn some complicated knowledge and actions too early, such as writing and memorizing uncommon words, otherwise it will not be conducive to their healthy growth. I hope it will help you and be adopted.
