A careful study will reveal that many children are careless, playful and not serious in life. In the face of what they think is boring and unimportant, 80% or 90% of adults will also make careless, playful and unimportant mistakes. Psychologists abroad have long noticed this so-called learning disability. Our ancestors did not force children to do calculations when they were young, but asked them to recite a lot to exercise their memory.
I think that when educating children, we must find ways to make ourselves consider the problem from the perspective of children, carefully study the root causes of the problem and solve it. Never make subjective assumptions and follow the trend. For example, the teacher asked the children to draw green grass, red sun and blue sky. The child painted green grass, green watermelon and blue sky. A teacher can't judge a child simply because of a painting mistake. Because the child is color blind, he can't tell red from green in his eyes. To put it more figuratively, in the eyes of children, a good uncle who gives sugar and a bad uncle who gives sugar are indistinguishable.
In the face of a bad answer sheet, you can ask the child to do it again and find out the reason for his doing so in time. If it is determined that it is only a calculation error, I suggest you take your child to learn quick calculation (it must be mental calculation) first. After some intensive training, there will be no mistakes. After all, counting numbers is only a technical activity, and judgment, understanding and perception are the most important abilities to determine a child's future.
What you must be reminded here is not to worry too much about your child's teacher. You must be careful when choosing a teacher. You'd better choose a younger, caring and more civilized teacher. Prevent teachers from beating, cursing, humiliating and intimidating children because of their temporary poor grades. If the teacher scolds the child for being stupid at school, the parents also say that the child is careless, so that the child's self-confidence and positive attitude of communicating with the outside world will be dampened.
Parents should also accompany their children to do some exercises and homework, compare them after completion, and give them corrections or suggestions. After all, parents are the best teachers for children. Parents' answers are not wrong, and children will also enhance their confidence and yearning.
At any time, you should understand that no one really cares about your child's feelings except yourself.
