In primary school mathematics teaching, the cultivation of computing ability is basic and very important. In the process of cultivating computing ability, the training of observation, memory and expression ability can be infiltrated, thus laying the foundation for developing students' intelligence. Some students are bored and uninterested in calculating problems. Therefore, when calculating, we can't look at the problem comprehensively and accurately, can't analyze the problem carefully and patiently, and can't choose the algorithm correctly and reasonably. If you don't see the topic clearly, you can't check it, resulting in calculation errors. So how to overcome it? I think we should train from the following aspects to cultivate students' good computing habits.

First, strengthen basic skills training and strive for everyone to pass.

1. Pay attention to the basic training of oral arithmetic. In the first three minutes of math class, students are arranged to have natural and rapid oral arithmetic training. Attention should be paid in training: first, teachers should show oral arithmetic problems in combination with teaching practice; The second is to open up a way to make questions, so that students can make their own questions, and everyone in the class can participate and turn them over. Before each class, there are fifteen cross-calculation problems. Students prepare their own oral cards. The students who gave the questions in the last class showed the questions, and the rest of the students did oral calculations. This method not only cultivates students' computing habits, but also improves the flexibility of their learning methods. You can also listen and watch with mistakes that students often make and confusing exercises. This kind of intense and orderly training can arouse students' great interest. In oral arithmetic training, we should pay attention to every student, especially the poor students, so that they can improve their oral arithmetic ability through more practice, so that every student can have fast and accurate oral arithmetic ability.

2. Strengthen the training of students' operating speed. On the correct premise, we should be flexible and fast, and train students to correctly use the calculation rules to guide the operation. In the process of operation, correctness is the first, but speed is also very important. Therefore, on the basis of students' reasonable application of calculation rules and correct operation, speed training should be carried out to train students' operation speed regularly and quantitatively. Practice has proved that paying attention to correcting some bad habits in calculation and cultivating students' good learning attitude and calculation habits are important measures to improve students' calculation ability. When good study habits are formed, students will strive harder for the accuracy of calculation, thus improving the accuracy of students' calculation.
