Q: Many teachers and parents have found that when students study mathematics, sometimes there are not too many complicated calculations in practice, but there is still a high error rate. Then why do students always make so many calculation mistakes when studying mathematics? What should parents do?

A: The calculation error is really a stumbling block in the process of mathematics learning. There are actually many reasons. Here are some.

Reason one: insufficient attention. Many students are psychologically contemptuous of the problem of calculation. Don't they always think that calculation is just "doing problems"? What's so hard about that? I always feel that I can just do the math casually. Ignorance of thought leads to careless examination of questions, wrong operation symbols, wrong operation rules and so on.

Reason 2: Bad calculation habits. Some students' handwriting is scrawled when calculating, which leads to the phenomenon of unclear reading and missing reading. Some students, no matter how big or small the numbers are, no matter whether they are skilled or not, always do oral calculations and are unwilling to write calculations; Some students never use special draft paper for calculus, and write calculus on the back and edge of desks, exercise books or test papers at will; There are also some students who are not focused enough in calculation, so they often make mistakes in copying wrong numbers and wrong operation symbols, and such small problems add up to big mistakes in calculation.

Reason three: the method is not skilled enough. For example, it is also a prominent problem in calculation errors that middle and senior grades can't use the algorithm correctly for simplicity. Some problems cannot be calculated simply, but some students take it for granted that they can be calculated together. However, students can't carefully examine and analyze the problems that are easy to calculate, and they can't choose the right simple calculation method to complete them.

Reason 4: I can't consciously check. In the usual homework, few students can consciously check and check after the homework is completed. At the same time, many students will not check at all, but will only read the questions over and over again, and have not found any mistakes after reading them for a long time. On the other hand, sometimes he can't find it even if you tell him that he is wrong.

According to the above-mentioned causes of various calculation errors, I have the following suggestions for parents:

Keep a normal heart. Many parents can't tolerate too many mistakes and carelessness in their children's eyes, but do you know? Sometimes the more anxious you are, the more mistakes you make, and the less you know. For students of this age group, miscalculation is a common phenomenon among many children. When carrying out corrective education, we must not lose patience and blindly adopt some "violent" means. First, it has no effect; Second, the effect is short-term; Third, the more violence, the more problems.

Don't do bad things with kindness. Sometimes many parents stare at a mistake and repeatedly criticize "how so careless", in fact, they are doing bad things with good intentions. Because it is always like this, in addition to making students lose interest in learning, they will also focus on his "carelessness". I think this question will make him feel helpless and insecure. Because of nervousness, it will lead him to repeat questions and make mistakes again. And if your anxiety affects your child's mood, it will only further strengthen the problem.

Sometimes kung fu transcends poetry. As the saying goes, "if you want to learn poetry, kung fu is above poetry." In fact, I don't think you need to say that students are careless. The problem of careless study may not be caused by study itself, but by his natural temperament and personality characteristics. You may pay more attention to exercising his meticulous behavior habits in your daily life, such as deliberately messing up the thread ball and asking him to help you straighten it out. He uses his attention and perseverance to help you keep a happy mood.

Provide some hints. Carelessness leads to calculation errors. In fact, "carelessness" also reflects that children have not learned to review and reflect on their learning process. You can teach him to try: write neatly, including every number, stroke by stroke; Read while writing, and turn unintentional attention into intentional attention; When checking, change the way of thinking and method, if it is still the original way of thinking and calculation, it is difficult to find out.
