Second, the reason:

1, if the child doesn't attend classes in math and Chinese, once he develops bad habits, he will lose more than he gains.

2, if the math language, teaching is wrong, especially the pronunciation of Chinese pinyin is not accurate, it is more laborious to correct.

3. There will be some differences between children who have studied Chinese mathematics and children who have not studied Chinese mathematics when they first enter school, but this difference will disappear after half a semester. Mainly in learning Pinyin, children who have attended school have a certain understanding of Pinyin and their spelling ability is slightly stronger. There is no difference in mathematics, physical education, music and other aspects, because the main physical exercise ability of children of this age is similar. If there is a difference, it is also determined by the child's own personality and physical condition, and it has nothing to do with whether he can go to preschool.

4. In the first semester of primary school, children have to learn more than 200 Chinese characters, but the preschool part is very few. After all, they don't study systematic primary school textbooks, and their reading or computing ability is limited. After a month or two, they ran out of Chinese knowledge in preschool and began to learn new content like other students.

In terms of attention or discipline in class, it is not because there are differences between mathematics and Chinese, but according to children's personality characteristics, some children are lively and active, while others are quiet. Teachers usually adopt active teaching methods according to children's age characteristics in class to make children willing to accept new knowledge.
