Mathematics curriculum standard points out that mathematics is an indispensable tool for people's life, work and study. An important task of primary school mathematics teaching is to cultivate students' correct and fast computing ability, which is very important for further study and future participation in productive labor. The present situation of computable teaching is thought-provoking, and students' computing ability is worrying! The calculation accuracy decreases and the speed of oral calculation slows down. It is worth discussing how to effectively improve the effectiveness of computing teaching, improve computing skills and develop mathematical thinking ability while cultivating students' interest in computing. I. My views are as follows: 1. The created situation should be closely combined with the students' real life. The new curriculum standard clearly points out that students should learn mathematics in life and feel the close relationship between mathematics and life. And can use mathematical knowledge to solve practical problems in life. Close contact with students' real life, so that students can clearly understand that the formula comes from our real life, not from the outside world. This is a good method, which can restore the true colors of mathematical calculation problems, better let students feel the value of mathematics in life, and thus stimulate students' interest in learning. 2. Leave enough time and space for exploration. Boglia said: The best way to learn anything is for students to discover it themselves. Because this discovery is the deepest to understand and the easiest to grasp the law, essence and connection. After the curriculum reform, teachers have such teaching ideas: return the right to study to students; Give students the time they want; Leave the opportunity to do it to students. Teachers consciously guide students to explore and discover, understand calculation and master calculation methods through interlocking questions in the new class. For example, what should be counted first? How to calculate? What is it? Let the students know clearly how to calculate, how to write and why to calculate. As the saying goes, we should know why, but also why. It is necessary to integrate arithmetic and algorithm, truly understand arithmetic, improve arithmetic, and finally form calculation skills. 3. We should advocate the combination of algorithm diversification and optimization. Algorithm diversification is the display of students' different personalities and different thinking results. Paying attention to diversification can be said to cultivate and improve students' thinking ability while optimizing the algorithm. In math class, it is common to see the diversification of oral calculation methods. With the encouragement of the teacher, the students have all kinds of oral calculation methods. Teachers should not blindly give affirmation: great! Creative! Teachers should give valuable guidance to students' oral arithmetic methods, guide students to compare and communicate, feel the characteristics of different strategies, understand the advantages and disadvantages of different methods, make reasonable judgments and value evaluations, make choices and self-adjustments, and seek simple, easy and fast methods. The teacher said: You can choose your favorite calculation method, but what the teacher likes is to better guide students to optimize and diversify on the basis of caring for and respecting students. 4. Strengthen the cultivation of verbal ability. Oral calculation is an important part of computing power, and it is also the basis of written calculation, estimation and simple calculation. I don't know when the students' verbal ability has declined. Some of them are not familiar with multiplication formulas, and some can recite multiplication formulas skillfully, but they can't use them well. It is often a simple multiplication problem in the table, but they have to recite it from the first line. What makes students' verbal arithmetic so bad? In my opinion, it has a lot to do with our usual oral arithmetic training. We often see that when teachers are training oral arithmetic, all formulas appear together, so it is difficult to improve the speed of oral arithmetic. Because when other students calculate the last question, some students are already calculating the next question, thus losing the meaning of verbal calculation. Can't achieve the expected effect. Therefore, the oral calculation questions should appear one by one. For example, showing them cards is a simple and feasible method. When designing a card, the front is the formula and the back is the result, which is quick and effective to operate. Interesting is effective. To improve students' oral arithmetic ability, it is necessary to combine it with improving students' interest in oral arithmetic. During training, you can use calculation forms such as competition, driving a train, rushing to answer questions, and checking passwords. Arouse students' interest in oral arithmetic, and then improve the frequency and intensity of oral arithmetic training, which not only realizes continuous training, but also improves the classroom, so that oral arithmetic ability can be improved orderly and effectively. 5. Cultivate good computing habits. Good calculation habit is the guarantee to improve the ability of approximate calculation. When calculating, the requirements for students should be: correct and fast, not fast and correct. In other words, it requires increasing the speed on the correct basis. It requires students to look at the questions carefully, calculate them carefully, and form the habit of checking. 6. Pay attention to infiltrating ideological and moral education. The Curriculum Standard of Primary Mathematics clearly stipulates that ideological and moral education for students is one of the goals and tasks of primary mathematics teaching. As Suhomlinski said, the goal of intellectual education is not only to develop and enrich intelligence, but also to form noble morality and good quality. It can be seen that it is very important to infiltrate moral education in mathematics classroom teaching. Therefore, teachers should be good at grasping all kinds of educational opportunities, infiltrate ideological education into the whole teaching process, and let students receive excellent ideological and moral education. Understanding ideological education is both teaching and educating people. In a word, mathematics is a culture and a skill. Calculation teaching can only be developed and improved harmoniously in arithmetic, algorithm and skills, so as to really improve the effectiveness of the calculation course, cultivate students' interest in calculation, improve students' calculation skills and develop students' mathematical thinking ability.
