In our primary school, calculation teaching can be said to run through the whole process of mathematics teaching, which shows the importance of calculation teaching. However, the accuracy of primary school students' calculation is often influenced by students' interest, attitude, will and habits. When doing calculation problems, students generally have a careless attitude. Some calculation problems are not impossible to do, but because of insufficient concentration, wrong copying, careless operation and no inspection. In order to effectively improve the calculation ability of primary school students, various measures and methods should be taken. In this topic, I have trained and studied mainly from the following aspects, and achieved certain results. First, pay attention to stimulate students' interest in active learning and improve students' computing ability. Interest is the internal motivation and foundation of learning. To be fair, calculation is really boring. It is necessary to cultivate students' interest in computing, stimulate their enthusiasm for learning and stimulate their thirst for knowledge. As teachers, we should try our best to attract students. 1, launch a computing contest. For boring calculation, scholars often deal with it casually after mastering the calculation method, resulting in calculation errors. At this time, properly carrying out some calculation competitions can often better mobilize students' initiative in learning, improve their interest in calculation, and achieve the purpose of improving calculation accuracy. For students with correct calculations, the implementation of small red flags has greatly improved the enthusiasm of students. 2. Enthusiastically encourage students and strengthen the experience of happy learning. We should enthusiastically encourage students to make mistakes because of carelessness. First of all, we must affirm its advantages, enhance self-confidence, and then put forward ardent hopes and urge it to correct its shortcomings. Second, pay attention to cultivating students' good computing study habits and improving their computing ability, which directly affects the formation and improvement of their computing ability. A large number of facts show that the lack of serious study attitude and study habits is one of the important reasons for students' calculation errors. Therefore, teachers should be strict with students and develop good calculation habits. In this study, I mainly focus on the cultivation of the following habits: 1. The habit of carefully examining questions. For application problems, most students can still carefully examine the problems, but for calculation problems, some students start to calculate. In addition, the calculation is monotonous and boring, which may cause psychological fatigue. At this time, when you encounter similar or similar numbers and symbols, you will often have an error in the operation order and copy the wrong symbols or numbers. Therefore, in teaching, students should be trained to carefully examine the questions and see each number and operation symbol clearly. In teaching, we can go in three steps: first, we should carefully check numbers and symbols, and observe their characteristics and internal relations; Second, we must carefully examine the order of operation and make clear what counts first and what counts later; Third, we should examine the rationality and simplicity of the calculation method and analyze the characteristics of the operation and data. And then start solving the problem. 2. Cultivate the good habit of checking calculation. Some students think that inspection is dispensable, but it is not. Checking calculation can not only ensure the correctness of calculation, but also cultivate students' meticulous learning attitude. For example, estimation can be used to judge the rationality of the operation results; In addition, the sum should be greater than each addend; In subtraction, both difference and subtraction should be less than the minuend, and so on. As teachers, we make up jingles with students: copy the questions and write at once; Check repeatedly during calculation; Check up and down when taking off; Check the whole after calculation. Of course, the inspection should have a clear purpose and strict standards, so that every question must be checked and every step must be checked. Step by step, check and check in time, correct mistakes in time, and ensure the correctness of calculation. Every teacher in our school pays great attention to students' habit of checking calculation. Every calculation problem requires students to improve their speaking style in the calculation process to check calculation, thus improving the calculation ability of all students. 3. Develop the good habit of standardizing writing. In my study, I strictly emphasize that the writing of students' homework and exercises should be neat and standardized. Ask students to draw lines with a ruler. The writing of numbers, decimal points and operation symbols in the topic must conform to the specifications and be clear and clear. Teachers should also set an example for their students. For example, in problem-solving teaching, the examination of questions comes first and the analysis comes last; The blackboard writing is concise and focused; The blackboard is vertical and has a ruler. Third, pay attention to cultivating students' oral computing ability, lay a good foundation for computing and improve students' computing ability. The Curriculum Standard for Primary Mathematics points out that to cultivate students' computing ability, we should pay attention to basic oral calculation training, which is not only the basis of written calculation, estimation and simple operation, but also an important part of computing ability. Only with strong oral calculation ability can we speed up the written calculation and improve the calculation accuracy. Therefore, every student should lay a good foundation of oral calculation, strengthen oral calculation training and improve oral calculation ability. First of all, I teach students the basic methods of oral calculation in teaching. For example, the composition of numbers is used to calculate the addition and subtraction within 10; Calculate carry addition within 20 by adding to ten; Do subtraction and want to do addition; Convert it into an integer ten plus or minus one digit; Conversion to addition and subtraction within 20; Convert two digits into one digit minus one digit; First, add and subtract two digits into two digits plus or minus integer ten, and then add and subtract one digit into two digits; Find the direct product sum quotient by multiplication formula; Perform oral calculation according to the multiplication and distribution law; In elementary arithmetic, students learn some arithmetic skills to improve their oral expression ability. Second, set goals and practice openly. It is required to arrange oral arithmetic exercises for 3-5 minutes before each math class, which can be carried out for a long time and can receive good results. Finally, various forms of exercises. Students, such as: do their own calculations, find their own oral calculation questions (calculations), and calculate each other. Students calculate each other's questions and calculate them repeatedly. Through repeated practice, their oral calculation ability will naturally improve. Teachers, such as: visual and numeracy training, listening and numeracy training, verbal arithmetic, verbal arithmetic games, "competitions" and "relay races". It is beneficial to stimulate students' interest in learning. Four. Existing problems and the direction of efforts In this study, I mainly focus on the cultivation of students' verbal ability, ignoring the cultivation of estimation consciousness and ability, which is my main work in the future. Make a good estimate, improve students' self-test ability and improve students' calculation accuracy. Of course, students' computing ability cannot be achieved overnight. As a teacher, we should first apply the calculation rules and laws freely, so that we can be handy in guiding and improve the effect. At the same time, training should be persistent, and it is difficult to get results by fishing for three days and drying the net for two days. In the teaching of calculation, we should constantly think and explore, not just calculate for the sake of calculation, but combine with the life reality and emotional attitude advocated by the current new curriculum standard to avoid the singleness and boredom of calculation. We believe that students' computing ability will continue to improve.
