Sort out the wrong problem set. Many children often make mistakes because of carelessness, but they don't analyze their mistakes carefully, so it is difficult to learn from them. When correcting the wrong question, it is not where the wrong question is and what the reason is, but just doing it again from beginning to end and doing it right, so it is useless to correct the wrong question. To sort out the wrong question set, we should copy the wrong questions intact in the wrong question set, leaving "error files"; Carefully check where the mistake is, and draw a curve under it with a red pen; Find out the cause of the mistake and write it down. To be specific, is the concept unclear or the formula wrong, unclear or sloppy calculation. Don't just write the word "sloppy" for sloppy mistakes. Write clearly how sloppy it is, whether to copy "+"as "-"or "3" as "5". The more specific the better. Finally, correct the mistakes and write the correct answers.

Find the real cause of the wrong question and correct it in time to avoid making the same mistake again next time. Carelessness is a common problem of children, the knowledge structure has not yet been formed, the mindset is not obvious, and the mistakes in homework are accidental and random. As long as children are taught to reflect on themselves and correct their mistakes, this is fundamental. You can ask him to correct it again in time, because the process of correcting children's mistakes is also a process of exploring success. With their physical and mental development, I believe that carelessness can be gradually overcome. We ask children to find out the cause of the error, whether it is a calculation method error or a verbal error, such as 15×3/5 = 1/25. This kind of mistake is that students have not mastered the calculation method of integral multiple scores.

Teach children how to check. Many children come straight with questions, but they never think they need to be examined. They leave the inspection work to parents and teachers and never take the initiative to find mistakes. Therefore, parents can make the following requirements for their children: 1. Slow down the operation speed and ensure that the question is correct; 2. After finishing, be sure to check independently; 3. The inspection method is to do an inspection, and then do the next one after it is confirmed.
