In the first oral arithmetic practice every day, parents can pick out several cross arithmetic 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 fast oral calculation, and at the same time avoids mechanical oral calculation practice.

Generally speaking, the oral calculation in lower grades adopts the methods of making up ten and making up one hundred or formulas. Parents can also read math books or communicate with teachers to learn other methods. When children learn some oral arithmetic methods, they can concentrate and stimulate their interest in oral arithmetic, which is helpful and more convenient for future oral arithmetic practice.

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.
