Don't let him spell every word at first, so he will soon get bored. It's best to refer to some simple syllables for him to practice, similar to "no" and "horse" with one initial and one vowel. Or words he knows, you try to teach him to spell. You will find that he will have a special sense of accomplishment. He must have exaggerated when he spelled it. But there is a problem here. Some children just can't pronounce initials and finals. Even though he has learned it, he just can't remember how to pronounce it or mispronounce it. At this time, parents can teach him to spell it again, such as "dad" and "b-a-ba". Let him be familiar with the structure of pinyin constantly, and let him have a basic impression of initials and finals, which is probably that initials come first and finals come last, thus forming a basic impression and sense of language.
Clever use of children's songs to increase the vividness and interest of Chinese pinyin is the earliest literary style that children come into contact with. It is always accompanied by children's play activities, and it is also one of the most willing forms of learning for primary school students. Children's songs are short and pithy, easy to understand, suitable for children's physiology, rhythmic cycle and strong musicality, and are effective tools for teachers to increase the vividness and interest of Chinese pinyin.
We must learn to read first. Pinyin is different from learning Pinyin when we were young. Now primary schools teach literacy first, which is more in line with children's cognitive laws. Learn pinyin after you have accumulated a certain amount of literacy. It will be easier to remember if you can associate it with the corresponding words immediately after spelling. At the age of 5-6, children can read when they know more words. With a lot of reading accumulation, phonological knowledge will be more handy.
