How to improve the accuracy of students calculations

Practice more, do more questions, repeat mental arithmetic, use the interesting communication of things with numbers around you at any time in daily life, guide, pen arithmetic, mental arithmetic, and you can give a certain reward after the calculation.

This is my experience.

How to improve the accuracy of the calculation of mathematics in the high school entrance examination, there are four methods for reference:

First, we need to pay enough attention to calculations. 62616964757a686964616fe4b893e5b19e31333431376564

Many students always think that calculation questions are much easier than analytical application problems, and they have learned some laws, laws and other knowledge more solidly, and calculation is a breeze, so they are overconfident or unable to concentrate when calculating, and the results are full of errors. Actually, it's not easy to get the calculations right. For example, to calculate a simple equation like 37 54, you need to use the rules of multiplication and addition, and you can complete it after four times of intra-table multiplication and four times of one-digit addition.

As for calculating a fraction and four decimal mixed operation problems, it requires a lot of knowledge such as the order of operations, the laws of operation, and the rules of the four operations, and has gone through dozens of basic calculations. In this complex process, a little carelessness can lead to miscalculations of the whole question. Therefore, the calculation should not be sloppy.

Second, it should be carried out in the general order of calculation.

First of all, clarify the meaning of the topic and see if there are any special requirements such as simple methods and keeping a few decimal places for the number; Secondly, observe the characteristics of the problem, see how many steps of operation, and whether there is a simple algorithm; Again, determine the order of operations. On this basis, the calculation is carried out using the relevant laws and laws. Finally, it is necessary to carefully check to see if there are any mistakes, omissions, and miscalculations.

Third, it is necessary to develop a good habit of serious calculus.

Some students make mistakes because they are not serious about the calculations. The data is not clearly written, and the identification is wrong. When making drafts, the vertical type cannot be arranged in a certain order, and there is adhesion up and down, left and right, and the same digits are not aligned, which is not easy to check and easy to read the wrong data.

Therefore, we must develop the good habit of arranging vertically in an orderly manner and writing numbers carefully.

Fourth, we can't blindly pursue high speed.

Calculation is the most ideal goal, but it must be known that correct calculation is a prerequisite and the most basic requirement, and high speed without the correct basis is worthless. Therefore, it is better to calculate slower, but also to ensure that the calculation is correct and improve the accuracy of calculation.

Ways to improve your students' calculation speed:

1. Strengthen the teaching of calculation rules.

The law of calculation is the basis of the calculation. If the rules are well mastered, students can quickly reproduce the content of the rules and choose a good algorithm after seeing the problem. Therefore, in order to improve the speed of students' calculations, it is necessary to strengthen the teaching of calculation rules, so that students can know what is and why they are in calculation, that is, they must not only master the algorithm, but also be able to say the arithmetic.

2. Make full use of the abacus.

Abacus is a tool calculation, which enables students to intuitively and vividly learn the rules of calculation and understand the arithmetic. When teaching, after the teacher teaches the method of dialing beads of an arithmetic, he also trains students to think about arithmetic while dialing beads, not dialing beads, only looking at the abacus and wanting to dial the beads, and not looking at the abacus and wanting to dial the beads, so that students can finally form a plate diagram in their minds. This has a great effect on improving students' computing speed.

3. Increase the training of multiple solutions to one problem.

The training of multiple solutions to one problem can enable students to make full use of their knowledge reserves, open up their ideas, and find the fastest method. When guiding students to solve multiple problems in one problem, the teacher can introduce them to methods such as "deformation" and "rounding".

4. Strengthen oral arithmetic training.

Oral arithmetic is a method of calculation based on thinking and verbal activities, and it is a basic skill that students should have.

1. Examination of the question is the key: 1. The number of the first trial should be comprehensively viewed to see whether the question involves integers, decimal numbers or fractions, or whether a topic contains two or three numbers at the same time; Second, we should also look at the numbers clearly to see if there is a special relationship between the numbers and the numbers: the same, each other is the reciprocal, etc. 2, the trial symbol, here refers to the operation symbol +, -

Observe how many operation symbols there are, and what they are; Whether it conforms to a certain law of operation or the nature of the operation. 3. Review the order of operations. In elementary school, we learned about the complex four mixed operations, and in the problems with ( ), we had to figure out the order.

At the beginning of the lesson, students can be guided to use markers to calculate the process.

2. Guidance of methods and skills: 1. Memorization of (1--25) times the value of pi; Memorize the commonly used decimals, fractions, and percentages, e.g. 1 8 = 1 125 =

3. Develop a good calculation habit for inspection.

To cultivate students' computing ability, we should pay attention to basic oral arithmetic training, insist on regular practice, and gradually reach proficiency, because any question is composed of several oral arithmetic questions, which is the basis of written arithmetic, and oral arithmetic ability directly affects the accuracy and speed of written arithmetic.

Attention is important, and "miscopied or miswritten symbols" is a manifestation of inattention. Students can consciously do some training to improve their concentration. The second is to treat the homework as an exam and concentrate on it - this can not only improve concentration, but also exercise the mind, so as not to panic and lose concentration in the exam room.

It reduces low-level errors – which directly affect test scores. Attention matters! Improving concentration, doing things can often get twice the result with half the effort, and greatly improve efficiency - this is a heartfelt statement, and I hope to accept it.
