Pupils often make mistakes of one kind or another in the calculation process. Many teachers and parents think that this is only caused by children's carelessness. It is necessary to objectively analyze the factors that cause students' calculation errors and make targeted corrections.

Two kinds of bad calculating mentality

First, contempt psychology: students think that the calculation problem is a "dead problem" and do not need to think, ignoring the analysis of the calculation problem and the check after calculation; Second, fear: students think that the calculation problem is boring. Whenever they see many calculation steps or large calculation figures, they will feel bored and lack patience and confidence, so the calculation is inaccurate.

Second, unskilled knowledge and skills.

This part of the calculation has no complicated conceptual nature. As long as students fully understand and firmly grasp, they can form very good computing skills. However, due to the lack of basic skills such as oral calculation, unclear calculation rules and lack of basic calculation skills, it is a major problem of calculation error.

Third, bad calculation habits.

Some students scribble in calculation and writing; Regardless of the size of the number, whether proficient or not, they are unwilling to write calculus; Some calculations do not use paper, and they are calculated at the back and edge of the exercise book or test paper on the table at will; After calculation, it will not be carefully checked by methods such as estimation and checking calculation.

According to the above analysis, in order to reduce the calculation error of students and improve the accuracy of calculation, practical methods must be taken according to the specific situation.

First, strengthen oral arithmetic training to lay a good foundation for other calculations.

Oral calculation is the basis of all calculations. Only when the basic oral calculation reaches a very skilled level can students pass the calculation well and form a good calculation ability. For this reason, I always use my spare time like five minutes before class to do some oral arithmetic exercises. Parents can also insist that their children do oral math problems every day. The content of oral calculation includes the oral calculation questions in this book and the basic oral calculation contents learned before, so that students can practice it repeatedly to achieve proficiency.

Second, design various forms of exercises to improve students' interest in learning calculation.

In order to cultivate and improve students' computing ability, it is necessary to achieve the goal through continuous and large-scale exercises, so that students can do a lot of monotonous test and calculation exercises repeatedly, which will easily lead to students' boredom and fail to achieve the expected results. Therefore, it is necessary to design diverse, flexible, targeted, knowledgeable and interesting exercises, use students' "initiative" and "competitive" psychology, design some math game calculation problems, stimulate students' interest in learning, and urge every student to actively participate in them, so as to get twice the result with half the effort.

Third, cultivate students' good computing habits.

1 Cultivate the habit of carefully examining questions. When reviewing the questions, we should look at them first (see clearly the numbers and symbols in the questions), cross them out second (mark which step to calculate first, then which step to calculate), think third (when to calculate orally and when to calculate with a pen, is it possible to calculate simply), and calculate fourth (calculate carefully with a pen).

2 cultivate the habit of careful calculation. Train students to be patient, not impatient, think seriously, and be cautious even when doing simple calculations. When calculating, you should write neatly and have a standardized format. Even if it is calculated on draft paper, it should be written clearly to facilitate inspection. 3 cultivate the habit of timely inspection. Be patient and careful when checking, check one by one. One is to check the number symbols, and the other is to check the calculation process. Summarized as a "step by step" calculation habit, check step by step when calculating. Check whether the copying of numbers and symbols is correct, whether the numbers are accurate, etc. And ask students to calculate patiently and carefully according to various corresponding calculation rules to overcome carelessness. 4 cultivate the habit of clever estimation. First, before the system calculation, the range of quantity can be estimated by estimation; Second, the system can judge whether this figure is correct and reasonable through the calculated estimate.

To cultivate students' computing ability, we must be regular, planned and step by step, pay attention to speed in time, have density in quantity, be flexible and novel in form and content, and persevere to get good results.

How to Improve Arithmetic Ability

I am an expert in mental arithmetic. It is absolutely right to practice more. The most common topic is 65x 12= 65456+55456= ````````````````` I write my own topic and do it myself. That's how I practice.

How to Improve Arithmetic Ability

Simply put, arithmetic ability depends on more calculations and mastering calculation methods.

As for enhancing memory.

Of course it can be changed. The following are the methods studied by experts from various countries, you can try ~!

Did you forget where you put your glasses and backpack again? Do you forget the wonderful joke every time you listen to a joke ... When people reach middle age, it is inevitable that their memory will decline. However, CNN10 reported on June 5438+05 that even if forgetting is a necessary experience in life, it is not immutable. Here are 9 ways to help you remember, so give it a try.

Play a thinking game: When you plan your day, you can connect it with creative ideas. Scott Hegewood, the winner of the Memory Contest and the author of Memory: You Can Cultivate Good Memory-An American Memory Master teaches you how to do it, said: "To say that you must remember to buy milk and take your son to the dentist, you should relate these tasks by imagining your son drinking milk, which overflows his teeth and deposits calcium."

Smell the roses: A new study in Germany divided some students who played matching cards into two groups. Let a group smell the roses first during the game and then before going to bed; The other group didn't. When they woke up, a group of students who smelled the flowers remembered the matching poker better. Therefore, in order to improve memory, it is beneficial to smell the fragrance of roses from time to time.

Roll your eyes horizontally for 30 seconds: British researchers say this kind of exercise can help you remember words. As for the reason, experts believe that turning the eyeball horizontally will make the left and right brains interact, which is very important for repairing memory.

Take a deep breath while meditating: Meditation in advance helps people to concentrate. Sonia Lupion, director of the Center for Human Stress Research at the Douglas Institute in Montreal, Canada, said that attention is the door to memory. Never thought about it before, did you? In a quiet room, or sitting or lying on the floor, put your hands on your stomach, take a deep breath, focus on this silence, and meditate for at least 10 minutes every day.

Learning a new language: Dr. Margo Laziman, director of the American Life Development Psychology Laboratory and professor of psychology at Brandeis University, believes that new ideas will help you clear your mind, such as learning a foreign language. You don't have to go to great lengths or master it skillfully. You can learn through educational CDs. You can try a new hobby, such as cooking or dancing.

Have a good sleep: this will refresh you and you can better face any situation that requires memory to dominate your body. The research of Israel Deaconess Medical Center shows that the cerebellum controls the speed and accuracy, and the activity of the cerebellum is particularly intense after adequate sleep.

When you are ready to leave, don't forget to "look back": if you look back carefully, you won't be embarrassed because you forgot to park your car four times in a row this week. It would be better if we could do it at any time.

Brush your teeth with your other hand: Not only that, you can also grow nerve cells in your brain by changing your daily habits, such as starting a new way of working.

Exercise for at least 30 minutes three times a week: A new study by scientists at Columbia University shows that exercise can promote the growth of a nerve cell in the brain region, which is closely related to preventing memory decline. Experts believe that it is good to engage in any aerobic exercise or strength training.

How to improve your arithmetic ability?

To learn mathematics well, senior high school students must solve two problems: one is to understand the problem; The second is the method.

Some students think that learning to teach well is to cope with the senior high school entrance examination, because mathematics accounts for a large proportion; Some students think that learning mathematics well is to lay a good foundation for further study of related majors. These understandings are reasonable, but not comprehensive enough. In fact, the more important purpose of learning and teaching is to accept the influence of mathematical thought and spirit and improve their own thinking quality and scientific literacy. If so, they will benefit for life. A leader once told me that the work report drafted by his liberal arts secretary was not satisfactory, because it was flashy and lacked logic, so he had to write it himself. It can be seen that even if you are engaged in secretarial work in the future, you must have strong scientific thinking ability, and learning mathematics is the best thinking gymnastics. Some senior one students feel that they have just graduated from junior high school, and there are still three years before their next graduation. They can breathe a sigh of relief first, and it is not too late to wait until they are in senior two and senior three. They even regard it as a "successful" experience to "relax first and then tighten" in primary and junior high schools. As we all know, first of all, at present, the teaching arrangement of senior high school mathematics is to finish three years' courses in two years, and the senior three is engaged in general review, so the teaching progress is very tight; Second, the most important and difficult content of high school mathematics (such as function and algebra) is in Grade One. Once these contents are not learned well, it will be difficult for the whole high school mathematics to learn well. Therefore, we must pay close attention to it at the beginning, even if we are slightly relaxed subconsciously, it will weaken our learning perseverance and affect the learning effect.

As for the focus of learning methods, each student can choose a suitable learning method according to his own foundation, study habits and intellectual characteristics.

How can I improve my arithmetic ability?

It must be mental arithmetic, there is no suspense. But first, you should practice your attention. I'll teach you a way to practice your attention. It's simple: when you are free, walk around and count the steps to see how many steps you can count. When you count, make sure you don't think about anything else. Just count two or three hundred steps at first, and add it every day. Don't underestimate it. This is very difficult. Then you will find it very helpful for your calculation. Of course, this is an aid. You should practice as much as you say upstairs.

How to improve children's arithmetic ability, and what good educational methods are there?

If you want to improve your child's arithmetic ability, you first need to find out which stage your child is currently in:

First, I won't do it;

Second, will do, not serious;

Third, I will do it and do it seriously, but there is always a small problem: the draft is made right but copied wrong, and there is a clerical error.

Then you can use the following methods to develop:

First, use poker to calculate quickly and develop mathematical potential.

Second, using chess to develop logical thinking ability,

Third, strengthen training.

Intensive training includes:

1, copying training (reducing copying errors and improving learning efficiency,

A. Copy the phone number (the left hand refers to the right hand to copy it to reduce mistakes)

B. copying numbers; (Check the online numbering rules for financial personnel)

C. write (full grid).

2. Habit cultivation:

A. posture training (correct writing posture can improve learning efficiency);

B. Cultivation of study habits

C. training in drafting. A good draft is conducive to inspection, especially in exams (disorderly, random and chaotic drafts will also bring some unnecessary troubles)

D. Training in writing and typesetting habits (many children make mistakes because of irregular writing,)

3, the training of learning methods (review previous homework, etc.). Good learning methods will benefit your children);

4. Plan training (some children are short of time because they have no plan, and planning can save children a lot of time to do what they want to do).
