How to improve the mathematical calculation ability of junior primary school students
A person's mathematical calculation ability mainly includes three aspects:

1, the accuracy of the calculation results;

2. Skills of calculation method;

3, the speed of calculation.

To improve primary school students' mathematical calculation ability, efforts should be made in the following four aspects:

First, let students master the law of operation skillfully: in primary school, students should learn three kinds of numbers-integer (natural number), decimal and fraction. These three numbers need four operations-addition, subtraction, multiplication and division. Each operation of each number has its own specific operation rules and is proficient in all kinds;

Second, pay attention to cultivating students' estimation ability: The new curriculum includes cultivating students' estimation ability, which fully embodies the importance of estimation in mathematical calculation and real life. Estimation ability is also an important aspect of a person's computing ability. It has good estimation ability, and practice has proved that it has four advantages:

1, help us predict the calculation results;

2. It can improve the ability of mathematical analysis;

3. It can solve real life problems;

4, check whether the results are basically correct.

Third, strengthen students' oral arithmetic training: In the classroom, the following steps are generally taken for oral arithmetic training:

1, let the students work out the results with their mouths first.

2. Let the students talk about their own oral calculation methods and affirm good oral calculation methods in time. Sometimes, for the same topic, ask students if there are any other oral calculation methods.

3. Finally, the teacher explained and emphasized the oral calculation method.

4. Be good at using simple algorithms: Some mathematical calculation problems have obvious characteristics of form and digital structure, which is a great opportunity for us to show simple algorithms. Through a certain number of simple calculation exercises, it not only improves students' observation ability and analysis ability, but also gradually strengthens students' skills and speed in mathematical calculation, and also gives them a pleasant spiritual enjoyment, which is of great benefit to stimulating students' interest in learning mathematics.
