In fact, the "loophole" of thinking is when checking this problem, because we don't believe that we will make mistakes in this link at all, so whenever we check this link, our thinking will automatically skip.

Although he was checking the problem again and again, he didn't check the simplest little link of 8 times 4. Therefore, it is precisely because of the existence of this thinking "loophole" that I have not found my own mistakes after many times of investigation.

2. Treat every assignment as an exam.

In the process of learning, students often hold "It doesn't matter if I do the questions at ordinary times, as long as I'm not careless in the exam!" "

In fact, this idea of students is very unrealistic. No one can be careless at ordinary times and take exams seriously. Besides, careless faults and careful habits are formed over time. Therefore, only when students consciously cultivate their serious habits in the usual learning process can they be really serious in the exam.

3. Encourage children to be fully prepared in advance and check repeatedly afterwards.

Children who can make full preparations in advance are often careful children. Parents can encourage their children to make a list before doing things, pay attention to the details, and then take into account possible accidents to cultivate their children's good habits of being careful and thoughtful. At the same time, let the children go back to check patiently every time they finish the task, which can reduce mistakes and avoid careless mistakes.

Extended data:

The reason why children are careless.

1, children's own physiological characteristics are prone to careless habits.

The bad habit of carelessness may be found in everyone, but it is more obvious in children. For example, toys and clothes are put by themselves, but they can't be found when they are used; The questions you will do in the exam, the answers in your mind are different from those written, and so on.

In the eyes of adults, sometimes children's carelessness is very funny and inexplicable. But this is not necessarily bad for children, because children are limited by the characteristics of physical development, limited memory ability, weak visual recognition ability and insufficient brain thinking processing ability. When the brain needs to run at high speed, it is easy to get confused and make mistakes.

2. There are too many tasks, and children are impatient and tired to cope.

Children are careless and careless, probably because there are too many tasks in front of them in a short time. Children are too anxious, eager to complete the task, and can only complete the task in the least time, so they gradually develop the bad habit of carelessness.

Just like many children in life, they usually finish their homework well, but once the exam comes, they need to finish the test questions within the specified time, and the questions they make will be terrible. Therefore, when the child is careless, parents should observe whether the child's carelessness is caused by pressure and many tasks.
