Why is calculation important for children?
First of all, the basic education system of mathematics in China is based on calculation, and other links in the mathematical system are inseparable from the assistance of calculation, so calculation is the basis of the mathematical system.
Secondly, calculation is the basis of solving all kinds of mathematical problems and life problems with mathematical tools, and bears the brunt, so calculation is the basis of mathematical application.
Furthermore, children who are good at calculation can exercise logic, such as the order of calculation. Being good at calculation can reduce the length of children's thinking, so calculation is the basis of mathematical thinking training.
How far does the child's calculation need?
For children, computing can be divided into five areas:
The first level is dead reckoning, which is the basic calculation from elementary school to grade one. This is the most basic level that children need to reach. There are three requirements: knowing logarithm, knowing symbol and knowing algorithm.
The second level is fierce calculation. The requirement at this level is that as long as the child knows the basic operation rules, all the problems can be worked out, which is actually to build confidence in the child.
The third layer is clever calculation, emphasizing methods. The first requirement is imitation, the second is to understand its essence in the process of imitation, then to understand, and finally to use flexibly.
The fourth layer is fast calculation, which requires children to reach a state, that is, accurate and fast calculation. This is actually a higher requirement for children, and this is the basis for children to get high marks.
The fifth layer is estimation, which is actually to cultivate children's sense of numbers, that is, to understand the range of numbers, which is a kind of ability that children should have.
Where is the problem of calculation?
The basic calculation is not solid: the basic operation rules are not clear. The problem is that children don't understand when studying or practicing and following up, and how to use it is not very clear.
Habits are not easy to be sloppy: habits can not be solved by saying a few words, but need to be accumulated and cultivated for a long time in training, which takes a certain amount of time.
Unskilled problem-solving skills: many problems need skilled calculation, that is, methods, but many children can't use them, mainly because they don't know the methods and are not skilled in them.
The steps of solving problems are not standardized: the primary school is not obvious, and the middle school is the main one. For example, solving equations is very easy to make mistakes because of irregularities. A big reason is that the proficiency is not enough and the basic content is not solid. The best solution is to write the process frequently.
How to conquer computing? -Principles
Correct mentality: There is nothing that can't be calculated, but some children are still on the road for the time being, which requires a certain amount of time and effort, and mentality is the most important.
Step by step: the training of calculation must be from shallow to deep. It is difficult to master the simple first, and then master it. High-rise buildings start from the ground and can only be lifted when the foundation is mastered.
Imitation and innovation: both learning methods and knowledge points are imitated at first, and in the process of imitation, they will produce their own cognition and then be used and innovated.
Timely feedback: Here, children are required to carry out repeated training and stimulation to ensure that they win in the weak links, because timely feedback helps children to make a detailed evaluation of the weak areas and correct the root causes of mistakes.
How to conquer computing? -Methodological articles
For calculation, the foundation is the premise, so we must lay a solid foundation for calculation, and secondly cultivate children's interest in calculation. Here, we need to pay attention to the cultivation of a sense of accomplishment and honor. For example, grades and rankings, primary schools should pay attention to interest, and middle schools should pay attention to grades.
Let children develop the good habit of calculating and solving problems, paying special attention to accumulating over time. The specific calculation habits can be summarized as: seeing (taking an exam), thinking (thinking), calculating (calculating), checking (taking an exam), and being cautious (finding a starting point, practicing one problem and solving many problems at ordinary times).
Children's calculation exercises must be standardized, which is necessary, and they should be skillfully memorized and mastered. When doing problems, we should be accurate first and then fast, and the weak links of key contents should be strengthened.
Children should master clever calculation problem-solving skills, and scientifically formulate exercise plans, especially skills and methods, which must be understood first, and then mastered through practice, so as to be more reliable, while scientific exercises, such as 3-5 questions per day for primary school students, and several questions per week if time is tight.
The above is a comprehensive interpretation of computing power. It is important for children to learn how to calculate well. I hope every parent can pay attention to it.
