Primary school can be said to be the most important period for children. The enlightenment of knowledge, the cultivation of habits, the cultivation of reading and computing ability, the consolidation of oral foundation, the cultivation of hobbies, the shaping of personality, etc. Almost all of them are formed in primary schools. These important things have three critical periods in primary school, namely, entering primary school, grade three and grade six. To sum up, these important things can be divided into four categories, namely:

Cultivation of three important abilities in primary schools;

Three things that affect life in primary school;

Three key periods of primary school can not be ignored;

What parents in primary school should remember.

We will discuss it in 12 articles. In this article, we talk about three important primary school abilities: the cultivation of computing ability.

Computing ability is a basic mathematical ability and a concrete embodiment of comprehensive ability. The cultivation of computing ability is not only closely related to the basic knowledge of mathematics, but also affects and promotes students' thinking and non-intelligence factors. How can we help children develop their computing ability in primary school?

First, mastering basic knowledge is the premise of forming computing ability.

In the face of calculation problems, if we want to get the calculation results, we must first consider what mathematical concepts, operation rules, operation properties, operation rules and calculation formulas are used, so fully understanding and mastering these basic knowledge determines whether we have the calculation ability.

For example, to learn the calculation method of the four scores, we must first understand the meaning and nature of the scores, and understand and master the basic knowledge and corresponding basic skills, such as the relationship between total scores, reduced scores, band scores and false scores. Only by explaining the basic knowledge clearly and letting the children really master it will there be no calculation errors.

Compared with the lower grades, the basic knowledge of the higher grades is more abundant. Therefore, in the process of imparting knowledge, don't rush for success, but help children to start from sorting out the basic knowledge they have learned and use migration to deepen it.

Second, strengthening basic skills training is the key to forming computing ability.

Learning mathematics, not solving problems, just talking about not practicing or practicing more and less will affect the improvement of computing ability. As the saying goes, "The fist never leaves the hand, and the song never leaves the mouth", so does improving children's computing ability.

In the process of children's learning, we should always urge and guide them to strengthen the cultivation of computing ability. Otherwise, they will make mistakes in the calculation. For example, when calculating the four operations of decimals and fractions, students often encounter that the calculation rules are correct, but the results are wrong. The reason is the error of induction and generalization, the error of reciprocity, and the problem of oral calculation within 100. These all reflect the defects of children's basic skills. In computing practice, strengthening basic skills training is an important link to improve computing ability. To this end, when guiding children to practice, we should be targeted and strengthen the training of basic skills.

In addition, helping children sum up some regular things can also greatly improve their computing ability. For example, the mixed operation of fractions and decimals is generally simple to calculate with decimals, but judging whether all fractions can be converted into finite decimals has become the focus of this kind of calculation. With the breakthrough of this key point, children's computing speed will be accelerated and their computing ability will be improved.

Third, master appropriate speech skills and cultivate speech ability.

The cultivation of oral arithmetic ability is an important part of primary school students' mathematics ability education. Only by grasping it effectively can it be conducive to the all-round development of primary school students' mathematical ability. Here are some practical operations.

① Use language cards to maintain the continuity of training.

Using language cards can stimulate students' enthusiasm for learning. Vision is the most sensitive organ in the process of perception, and it is easy for students to concentrate when looking at the mouth card for visual calculation. Generally, you can use the first two or three minutes to concentrate on training. For example, we make all the formulas of non-carry addition and non-abdication subtraction within 20 into oral cards, so that mothers can make cards quickly and children can do oral calculations quickly. Twenty cards are a round, and the best scores in history (including time and scores) are posted on the child's bedside. After each training, if the records are broken, they will be updated.

Now there are some games that can achieve this effect, but I still think the card effect is better.

(2) Master some fast calculation skills of rounding.

For example, add up to ten. Whether the calculation of "carry addition within 20" is correct and fast is the core of this part. How students master carry addition will directly affect the calculation speed of carry addition, thus affecting the abdication subtraction within 20 and the calculation of four integers. Therefore, it is very important to master the calculation of carry addition within 20 by using the "complement ten method".

In fact, addition, subtraction, multiplication and division can be applied to the fast calculation skills of rounding off ten.

Fourthly, cultivating good habits is an important guarantee for the formation of computing ability.

Some children, if they keep staring at the exam before the exam, their grades will change greatly. The reason is not that the basic things are not mastered, but that the usual habits are not good. Therefore, good study habits directly affect the formation and improvement of computing ability. This requires children to listen carefully, think positively, finish their homework independently, and develop the habit of consciously checking and correcting mistakes.

Let children develop the habit of reviewing questions before seeing them, so that the calculation method will be more correct and reasonable, and the calculation speed will be continuously improved.

It is common to make mistakes in calculation, so it is very important to guide children to write carefully. A standardized writing format can express the ideas and steps of operation.

It is true that cultivating students' good study habits can't be achieved overnight, and it can't be grasped. Only perseverance can have an effect.

In the whole primary school stage, the four operations run through the whole process of mathematics learning, and the whole primary school mathematics is learning it for more than half of the time. Therefore, helping children lay a good foundation, paying attention to basic skills training and cultivating children's good study habits can help children form strong computing ability.
