The cultivation of mathematical calculation ability in primary schools is a basic ability in primary schools. The cultivation of computing ability is the foundation of mathematics, and students' computing ability will affect the whole process of mathematics learning. At the same time, computing ability is an important tool for us to open the door to mathematical knowledge. Therefore, through my teaching experience, I want to talk about how to improve students' computing ability:
First, stimulate students' interest in computing?
Interest is the best teacher, using various forms of exploration and calculation exercises to master mathematical knowledge and skills. Simple calculation is boring, students are unwilling to do it, and even make students tired of calculation. Therefore, teachers should find corresponding forms and methods for different calculation exercises in their usual teaching activities, so as to stimulate students' interest in calculation. For example, "Mathematical black hole" uses "magic 495" to find the password and uses three different numbers to form the largest three digits. Adopt game forms such as "group competition" and "relay competition"; Use learning tools, teaching AIDS, multimedia and other ways to combine teaching content for training, so that boring calculation becomes rich and colorful. So as to fully mobilize the enthusiasm of students, and only in this way can the cultivation of students' computing ability be well improved.
Second, form the habit of collecting mistakes and correcting them?
Error correction includes two aspects: first, students collect mistakes and correct them themselves. Second, the teacher collects all the students' calculation mistakes and corrects them. In students' actual study, a large number of calculation problems are omitted, including knowledge and skill errors and careless errors. Collect these mistakes in the notebook, and after correcting them, you can always take them out to remind yourself not to make the same mistakes. For teachers, these wrong examples are the best teaching resources, and use these resources to teach and train students in a targeted manner. Kill students' mistakes in the cradle, thus effectively improving students' calculation accuracy. ?
Third, cultivate good computing habits?
? Computing habits directly affect the formation and improvement of students' computing ability. There is a famous saying: "We walked too far and forgot why we started". Mathematical calculation requires accuracy, one step wrong, one step wrong. It is too simple for teachers to impart knowledge, but it is quite difficult to cultivate students' interests and correct habits. In fact, some students made mistakes in some calculations, most of which were not "mistakes" in the real sense. Therefore, this requires teachers to be strict with students in the actual teaching process, urge students to be rigorous in calculation attitude and cultivate good calculation habits. Therefore, in teaching: first, we should cultivate students' habit of carefully examining questions and seeing numbers and operation symbols clearly, rather than blindly calculating; The second is to cultivate students' standardized writing. Students' writing includes handwriting and format, which is easily mistaken for "5" as 3 and "6" as 0; The format is not standardized and the numbers are misplaced, which easily leads to errors; Third, cultivate the habit of checking carefully. Students often make mistakes, mistakes and omissions in calculation, and the accuracy of calculation can be improved through repeated inspection. Of course, this habit is not formed in a day or two, and it is necessary to carry forward the spirit of perseverance and form a conscious good habit. ? Fourth, strengthen the calculation practice? .
? Strengthening the training of computing skills is an important link to improve computing ability, which includes oral computing ability, estimation ability and written computing ability. The skills of oral arithmetic estimation are ignored by some students at some stages, which has a great influence on written arithmetic. We should not only practice the calculation methods we have learned in time, but also practice all kinds of calculations persistently and take various forms of intensive exercises to improve our calculation ability effectively and comprehensively. ?
? The cultivation of students' computing ability is a long-term process. Under the correct guidance of teachers, students' serious attitude and unremitting efforts, the computing ability will be gradually improved.
