A few days ago, a mother asked me in a private letter: "Mother Han, my child is now in a large class and has started to learn Pinyin, but he always writes the letters backwards and teaches them many times, but he still makes the same mistake." He pays no attention to his study at all. What can he do? "

In fact, it is normal for children to write letters or numbers backwards. Han Han often asks me while writing:

"Mom, mom, is 6 above or below?"

"Mom, does P face turn left or right?"

When Han Han was 4 years old and 7 months old, she saw me writing reading notes, and she sat next to me and wrote them. She wrote all the black ones, but she can't remember how to write the other colors. When she asked me, I wrote it opposite her. You can see that some letters and numbers are upside down.

At the beginning of learning to write letters or numbers, children often can't tell "6 and 9, 5 and 2", "P and Q" and "B and D".

But it will get better gradually. For example, just after my fifth birthday, I won't struggle with the question of extreme left or extreme right when writing numbers or letters, but I will occasionally make mistakes and find them after writing.

This is the name of the book that Han Han wanted to write by himself when we took reading notes last night. In fact, it is "painting words", but it is getting better and better.

In the process of learning, children's brains will have this primitive phenomenon, not only left and right, but also up and down, such as "9,6", which is collectively called symmetry confusion. Seeing symmetrical things can easily confuse the brain, just like the reflection on the human retina.

Scientists who study children have found that most children will go through such a "mirror stage". This is because children's visual perception and sense of space are not strong.
