(A) mutual integration, learn from each other.

We can effectively integrate abacus mental arithmetic into mathematics teaching, not only can we further integrate mathematical operations into abacus mental arithmetic to help students better understand arithmetic, so as to sum up the methods of pearl picking by themselves and master the skills of pearl picking in continuous practice; Moreover, abacus mental arithmetic can be introduced into mathematics teaching, so that students can improve the calculation speed and accuracy through abacus mental arithmetic on the premise of mastering arithmetic.

In this way, abacus mental arithmetic can be integrated into the teaching of primary school mathematics, which has good effects in many aspects of mathematics, such as the related calculation of the number of objects. We should learn to give students a chance to study independently before teaching, so that they can discuss and explore to produce their own results, and then explain their classmates' confusion, so that students can understand knowledge more deeply.

(2) Enhance thinking and experience.

Each of us is an individual, we can think independently, and we will accumulate experience through the process of thinking about problems and apply these experiences to actual situations. This kind of thinking is often accompanied by our thinking activities and requires some knowledge of mathematical calculation. These thinking processes are solved through our own experience and thinking, and we don't need outside help.

We can design some vivid research activities in some interesting ways. At this time, we can combine them through mental arithmetic, so that students can develop the habit of being willing to think, diligent in thinking and good at thinking, and sum up experience in thinking.

(C) into life, internalized experience

Practice is a highlight of the textbook reform of Jiangsu Education Edition. At present, some primary schools in Jiangsu Province have become experimental schools for abacus mental arithmetic, and abacus mental arithmetic is fully taught in grades one to three. Because many teachers are new to abacus mental arithmetic, the research on the teaching content and methods of abacus mental arithmetic is not deep enough, and it is difficult to achieve the teaching goal in the 40-minute course because of the teaching time and students' operational ability.

However, most students' experience in mathematical activities is accumulated through practical activities. We can link mathematics with life through practical activities, so that students can understand mathematics knowledge more deeply and use what they have learned to solve practical problems in life. Therefore, abacus mental arithmetic can be integrated into the classroom of mathematical practice activities, so that the two can promote each other and integrate with each other, and finally help students improve their problem-solving ability.
