Mathematical oral calculation skills in the first grade of primary school

The skills of oral math in the first grade of primary school are as follows:

1、? Cultivate interest in arithmetic.

To improve children's oral expression ability, it is essential to cultivate interest. If children hate verbal arithmetic, even if there are a hundred ways to improve it, it is useless to them. For children in lower grades, cultivating their interest in oral arithmetic can be carried out in the form of lively and interesting oral arithmetic games.

Here are some methods that parents can try, such as answering first, verbal relay, verbal contest, etc. Stay with their children, or edify them anytime, anywhere. With the variety of forms, children's interest in arithmetic is naturally stronger.

For example, a speech contest: mother is the referee, and children compete with father. Mother read the question quickly, and the child and father scrambled to answer it. The person who answers correctly scores points, and the winner is rewarded. Or when shopping in the supermarket, you can let your child check out; Or when children are reading a book, ask them which page they have read today and how many pages they have read ... Under the influence of these forms, verbal arithmetic has come to life and become an interesting and happy thing for children.

2、? Read the questions aloud.

When practicing oral arithmetic, children can read aloud. It may be a little slow at first, but it can be repeated several times to improve the speed. At the same time, record the time of each practice, so as to compare and understand the child's progress. 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.

In addition, in the process of children's rapid oral calculation, it is advisable 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 children's thinking agility.

3、? Tell me how to calculate.

In oral arithmetic practice, you can pick out several math problems, let the children talk about how to calculate, and see if the children are clear about oral arithmetic. This is the basis of correct and fast oral calculation, and it also 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. 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.

4、? Keep practicing every day.

To cultivate children's verbal ability, we should give priority to peacetime and insist on it. Ensure that children practice oral arithmetic for 3-5 minutes every day. On the other hand, the content of oral arithmetic training every day should be organically combined with the content learned that day as far as possible, which plays a good role in consolidating.

5、? Good language habits.

Oral arithmetic errors are mostly caused by bad habits such as carelessness of children. Therefore, good habits are the guarantee of improving computing power. Therefore, it is very important to form a good habit of oral calculation.
