How can I improve my mathematical calculation skills

1. Cultivate oral arithmetic ability and pay attention to training.

To cultivate students' numeracy skills, we must first start with oral arithmetic skills. So I insist on doing it: 1. Practice every day, arrange oral arithmetic training in each class, no more, just 10 questions.

2. Change training in a variety of ways. Such as: listening and arithmetic training, rush answers, "** car", etc.

In this way, it not only trains students' listening, but also enables students to concentrate on learning in a short period of time, and also improves students' numeracy ability. However, training focuses on perseverance and perseverance, and only in this way can better results be achieved.

2. Advocate the diversification of algorithms and improve computing skills.

I advocate the diversification of computing teaching algorithms, advocate and recommend an optimal computing method, teach students according to their aptitude, and explore the mathematical potential of each student.

3. Cultivate good habits and improve the effectiveness of calculations.

In order to improve students' numeracy ability, it is necessary to pay attention to the cultivation of good numeracy habits.

1) The habit of carefully examining questions. In my daily teaching, I ask students to: 1. examine numbers and symbols, observe what characteristics and internal connections they have; 2. Review the order of operations, and clarify what is counted first and then counted; 3. Review the reasonableness and simplicity of the calculation method, analyze the characteristics of the operation and data, connect the nature and laws of the operation, judge whether the calculation can be simplified, and then start to solve the problem.

2) The habit of concentrating on proofreading. The most obvious psychological characteristics of children are competitiveness, eager to be happy, and often do things when they see them, regardless of the future. Therefore, in the actual calculation, students are required to carefully compare, and after copying, they should compare with the numbers and symbols in the original question, so that they are exactly the same word and foolproof.

Multi-computation. Skill comes from practice. Just practice. to be able to increase your computing power.

Dear, give it one.

Pay attention to the cultivation of oral arithmetic and estimating ability.

Pay attention to the teaching of calculation methods and ideas.

Flexible application of easy methods.

Estimation is an open-ended method of creation, often with indefiniteness. How to estimate based on conditions, how to extract the main information, which information is negligible. The formation of these skills runs through the whole process of learning, and the ancients said: "It is better to teach a man to fish than to teach him to fish." ”

In the learning process of estimation, since there is no precise requirement, it mainly depends on whether the estimation method is correct. The commonly used estimation method is to estimate two numbers at the same time or at the same time or one at the same time, and one is estimated to be large, and one is estimated to be as small as ten or hundred, so that it is convenient to calculate a rough number or range. For example:

397+103 can be simplified to 400+100, which translates into 2 3

Some calculations are actually very simple for students, and most students can do calculations even if the teacher doesn't teach them. However, as a teacher, we must not only be satisfied with students' ability to calculate, but let students understand arithmetic from the process of solving problems, summarize the rules, and participate in the whole process of knowledge formation.

For example, in the teaching of three-digit multiplication of two-digit numbers, 102 24, from reviewing the arithmetic of two-digit multiplication of two-digit numbers to three-digit multiplication of two-digit numbers, most students can quickly calculate 102 24, and students habitually write 102 on it and 24 below 102 when they are vertically listed. Students start to make mistakes, and they don't really understand the calculations.

So, a computing lesson is more than just numeracy. To involve students in the process of calculation, not only to know how to calculate, but also to know why it is the way it is, this is the real purpose of the calculation class.

Many students think that the simple method is a type of calculation problem, and most students can do it when they say "calculate with the easy method", but when the same formula is put in the application problem, the student will not think of using the easy method.

For example, for the calculation of 38+75+62, put it in the application problem, for example: Arbor Day, four (1) classes planted 38 trees, four (2) classes planted 75 trees, four (4) classes planted 62 trees, how many trees were planted in these three classes?

Students quickly list the formula: 38+75+62, and then calculate the answers in the order from left to right, and there are few students who use the easy method. Therefore, it is necessary for students to appreciate the value of simple methods, and make them as simple as possible.

In addition, if students are familiar with some common data in the four operations, they can better grasp the skills and skills of calculation, which will help students' computing ability to meet the requirements of "correct, fast, reasonable and flexible". For example, 25 4 = 100, 125 8 = 1000, etc.

<>1. Do more and practice, practice makes perfect.

Freezing three feet, not a day's cold", calculation ability is a child's essential basic skills, we should make a long-term plan, short-term arrangement, purposeful, planned, step-by-step teaching and training.

In daily life, we should insist on 3-5 minutes of oral arithmetic training every day, and insist on practicing 10 oral arithmetic problems every day. In this way, while strengthening the child's oral arithmetic ability, the child's writing habits and concentration habits will also be strengthened.

At the beginning, it can be completed under the supervision of parents, and slowly let go of the children to form habits and complete them consciously and voluntarily.

2. Quality and quantity training.

Record the time it takes to complete one page of each exercise, correct the correctness and analysis of the cause of the error immediately after completion. Every time you do a training session, compare it with the speed of the last time to see if there is any progress, and if you make progress, parents should praise the child appropriately.

Children need to be encouraged in a timely manner, just as a player who is struggling on the court needs his teammates to be cheerleaders, and they can also be encouraged to post their excellent practice in a prominent place at home, and sometimes give them a small prize.

Parents must not be impatient when they see their children's speed a little slow, and say, "What stupid, how can you do it!" "If you are a parent, it will have a detrimental effect on your child, and it is something that requires patience and love to do well.

For children who have regression, you can analyze the reasons for regression with your children, and then gently touch their heads to suggest what they should do in the oral arithmetic in the future, and praise them in time if their grades improve next time, encourage them to continue to work hard and build self-confidence.

3. Diversified training forms.

Doing more and practicing is the premise, but children are used to being interested in new things, especially like to learn in games to increase their knowledge, if a long-term practice alone, children are easy to feel bored.

As a result, the practice method can be lively, vivid and diverse, and the supplementary ways that can be used in the practice are: playing poker (24 points), listening to the calculation, ** car, matching passwords, grabbing the red flag, sending letters, finding friends, regular testing and so on.

At the same time, through some practical mathematics activities, children can experience the importance of numeracy ability cultivation to our daily life, such as grocery shopping, supermarket visits, etc.
