Mathematical operation ability is to improve operation speed and accuracy. Nowadays, children are careless and waste a lot of precious time in calculation. Strengthening this training can improve the calculation speed and accuracy in a limited time.

First, strengthen students' intentional attention and good calculation habits.

Students are required to be careful when calculating, from examining questions, calculating to writing. Cultivate students' good habits of writing neatly, standardizing the format, consciously checking and checking at any time. To do the following:

(1) The habit of carefully examining questions. Educate students to carefully examine the questions after getting them, see the requirements of the questions clearly, understand the problems that should be paid attention to in the calculation process, and then start the calculation.

(2) the habit of careful inspection. Let the students start with the topic and check it step by step. Check the operation symbols first, then check whether the numbers are moved or copied incorrectly, and then check carefully to see if the results are consistent, so as to achieve the purpose of checking. You can also look at your own calculation process and do the problem again to see if the results are consistent, so as to find the problem.

(3) the habit of writing carefully. Teachers should educate students to write all their homework neatly, even if it is practice, so that students can see the questions clearly and avoid making mistakes when doing them.

Second, strengthen the ability of oral calculation.

Any calculation is based on oral calculation, and the ability of oral calculation directly affects the improvement of students' other calculation abilities. To improve the teaching effect of oral arithmetic, we must first do a good job in basic training of oral arithmetic. Oral calculation is the basis of written calculation, and oral calculation should be practiced in combination with students' specific conditions. These targeted exercises not only consolidate the calculation theory, but also help students calculate the speed. There are often some simple calculation exercises in oral calculation, which can not only consolidate the learned operation rules or properties, but also improve students' ability to process data and information in mixed operation, and find out what can be simplified from mixed operation, so as to optimize the calculation and improve the accuracy of the calculation.

Third, strengthen the computing power.

Strengthen the training of basic computing skills, insist on practicing basic computing skills every day, and achieve proficiency. In calculation, a variety of teaching methods and means can be used to guide students to learn the methods and habits of calculation and thinking step by step, so that students can understand and master the law of operation, which is the premise of improving the correctness of operation. The study and training of operating rules is helpful to cultivate students' basic skills and abilities. You can play the leading role of eugenics in class, let them explain the operation independently and then guide the whole class to speak. Or classmates at the same table will whisper, talk to each other and so on. Improve the ability of speaking and reasoning, and gradually develop students' computing ability through certain training. Let students know not only how to calculate, but also why. In this way, students can not only understand arithmetic, but also integrate what they have learned and cultivate scientific and effective thinking methods.
