How elementary school students can improve their calculation accuracy

1. Guidance on the cultivation of oral arithmetic ability.

Oral arithmetic is the basis of estimation and written arithmetic, and any four mixed arithmetic problems are composed of several oral arithmetic problems, and the correctness and rapidity of oral arithmetic are directly related to the improvement of computing ability. (1) Strengthen the basic oral arithmetic and lay a solid foundation for oral arithmetic; (2) Pay attention to the form of training and stimulate interest in oral arithmetic. Such as games, competitions, rush answers, etc.

in the form of cards, chalkboards or playing cards; Pay attention to exploring the rules, improve the speed of oral arithmetic, enhance the awareness of oral arithmetic, develop the habit of oral arithmetic, and strengthen comprehensive training. (3) Some commonly used special calculation data, such as 8=1000, fractions, decimals, percentages of the interaction of simple common numbers: 1 4=, etc

14 4 4 = etc., students should be able to memorize it proficiently, memorize it repeatedly, and be able to twist it when they need it. Of course, the cultivation of oral arithmetic ability should focus on ordinary times and persistence.

2. Basic skills and practice methods.

In numeracy exercises, strengthening the training of basic skills is the most important step in improving numeracy skills. For example, in the teaching of fraction four, there are often some students who have the right way to process. However, the reason for the error in the calculation results is in the basic skills such as reduction, general or mutualization, which reflects the students' deficiencies in basic skills.

In the course of practice, it is necessary to take measures to strengthen training and guidance in a targeted manner. In addition, in the calculation exercises, it is necessary to guide students to discover and summarize certain regularities, so as to help them skillfully use the basic knowledge to calculate and continuously improve their computing ability. In particular, it is necessary to strengthen the comparative practice of confusing and erroneous questions, find differences in the comparative practice of similar questions, and form a correct appearance, so as to eliminate the negative transfer of fixed thinking.

The form of the exercise should be varied, and some judgments and interesting questions can be added appropriately. Form should serve content. However, it is necessary to pay attention to the grasp of the "degree" of practice, and we cannot only talk about "quantity" without stressing "quality." Engaging in tactics will be counterproductive.

This not only reduces the burden on students, but also increases students' interest in learning.

3. Cultivate students' estimation ability.

Strengthening estimation can promote the development of students' number sense. Estimation plays an important role in the teaching of computing, and the awareness and method of estimation should be gradually infiltrated in the teaching of computing. It helps students to find their own deviations in solving problems in a timely manner, rethink and calculate, so as to prevent and reduce errors and improve their computing ability.

To improve the accuracy of the calculation, let him finish the calculation problem and then check it.

1. First, the amount of oral arithmetic practice is slightly more than the amount of exam questions. In this way, it is easy to solve the problem that some children usually practice less and cannot finish the exam. If you can calculate and complete 70 oral arithmetic questions in 5 minutes, then the amount of questions in the exam will be completed in one fell swoop.

2. The second is to strengthen students' psychological training and reduce tension. Many children are reluctant to be supervised by their parents when they do the questions, which is not conducive to training children's cracking and concentration, nor is it conducive to training children's psychological endurance. Parents should not only supervise their children's oral arithmetic practice, but also make some noise and other external factors from time to time, walk around their children from time to time, imitate the atmosphere during exams, etc., all of which are conducive to helping students overcome their nervousness.

3. The third is to apply the practice of oral arithmetic to daily life. The ultimate purpose of learning is to serve work and life, and it is necessary to train students to apply the knowledge they have learned to their daily lives, so as to achieve the realm of applying what they have learned. The calculation application in life is not only integers and decimals, not only a single operation of addition, subtraction, multiplication and division, but also a variety of compound operations, which is more conducive to improving children's oral arithmetic ability.

For example, when shopping in the supermarket, the calculation of commodity ** involves the multiplication operation of the unit price multiplied by the quantity, and the settlement involves addition and subtraction operations, etc.

4. Fourth, enhance the interest of oral arithmetic practice to avoid boring monotony. I remember when I was in elementary school, there was no condition to print oral arithmetic articles like now, and some of the mimeographed ones were very high-end, and most of them were copied by hand. At that time, doing oral arithmetic problems was even more boring.

At present, parents can accompany their children to do some small games to give oral arithmetic calculations to the game; You can also find some oral arithmetic software from the Internet, so as to improve the interest of oral arithmetic calculation.

Train 100 quick arithmetic questions within two digits every day, and limit the time, don't blame the child if you are wrong, but encourage more, and practice more quickly.

If I want to improve the speed and accuracy of my calculations, I need to do more oral arithmetic question sheets, and if I calculate in a certain amount of time, long-term training will improve.

When I was in elementary school, I could improve the speed and accuracy of calculations, and I could only improve by doing more problems and practicing.

The best way for elementary school students to improve their calculation speed and accuracy is to do more problems, so that practice makes perfect.
