How to improve the speed of oral calculation in the first and second grades of primary school?
When parents coach their children in oral arithmetic, the first thing they need to pay attention to is the way their children practice oral arithmetic, that is, they practice "speaking", "reading" and "writing" three times respectively to achieve the three requirements of clarity, speed and accuracy. Practice more and complete the above three requirements, and the speed of oral calculation will be improved.

The logic of "saying" should be clear.

In the first oral calculation exercise every day, parents can pick out several math problems and let their children talk about how to calculate them. The focus of this kind of exercise is to see whether the child's understanding of oral calculation is clear, which is the basis of correct and rapid oral calculation, and at the same time avoids mechanical oral calculation practice. In the lower grades, oral arithmetic generally adopts decimal rounding up to 100 or formula.

Verbally "read" and calculate quickly.

The second oral arithmetic practice every day can make children read aloud oral arithmetic questions, which may be a little slow at first. You can come back for the second and third time and record the time of each exercise for comparison and continuous improvement. After this kind of reading and calculation training, children can calculate skillfully and quickly without thinking or memorizing formulas, and they can also train their reaction ability and calculation speed to make their attention highly concentrated. On the other hand, in the process of children's rapid oral calculation, parents may wish to disrupt the order of oral calculation questions, so that children can flexibly use oral calculation methods according to different oral calculation questions, so that oral calculation is reasonable, flexible and fast, and gradually exercise their mental agility.

"Writing" and oral calculation need to be correct.

The third oral arithmetic practice every day can make children write the oral arithmetic questions they have seen before quickly, and then parents can correct them, so as to know the correct rate of their oral arithmetic. This exercise is about the unity of reading and writing. It is a comprehensive application of understanding, calculation and proficiency. We shouldn't act in haste. After such repeated practice, children can calculate basic oral calculations correctly and quickly.

After children master the method of oral arithmetic practice, there is still a certain distance from forming good oral arithmetic skills. At this time, parents need to pay attention to two points, cultivate their children's interest in verbal arithmetic, and insist on verbal arithmetic training.

Cultivating children's interest in verbal arithmetic can be carried out in vivid and interesting forms. This is very important for children in lower grades. If a single way is often used for oral arithmetic training, it will inevitably make them feel bored, inattentive and ineffective. Here are some methods that parents can try, such as competing with their children for answers, verbal relay races, verbal contests and so on. Or edify them anytime, anywhere. With the variety of forms, children's interest in arithmetic is naturally stronger.
