Calculation is the foundation of primary school mathematics, and the level of calculation ability reflects the firmness of students' mathematical foundation, which directly affects their future mathematical study. Therefore, it is very important to cultivate the computing ability of junior primary school students. These methods are as follows:

1, cultivate students' interest in computing. Interest is the motivation to maintain students' learning activities. Only when students are interested will they take an active part in learning.

2. Encourage students to actively look for calculation methods. Encourage and advocate the diversification of algorithms, and encourage students to find more reasonable and simple calculation methods through independent thinking, so as to realize the diversification and optimization of calculation methods;

3. Cultivate students' good computing habits. Many students make mistakes in calculation, mostly because of bad calculation habits such as carelessness and sloppy writing. Therefore, developing good computing habits is the most important thing to improve students' computing ability.
