How can high school students improve their numeracy skills?

Back. It will definitely be useful to do more arithmetic exercises, but since you are already in high school, you must already have the comprehension required for numeracy skills, so the best way to improve your numeracy skills in a short period of time is to memorize! Specifically, it is to memorize the 19 19 multiplication table and write down this **, which can cope with the calculation requirements of most topics, especially the square of some numbers, and the cube should be written down.

When memorizing the 19 19 multiplication table, you don't need to spend a lot of time memorizing, you can make a ** at home, read it every day, and often look at it will naturally form a memory. Here the back also includes trigonometric values for various typical angles, formulas for special points, special lines and the memory of their results, etc.

Of course, it is to do more questions, but to choose to do more questions, I once participated in the Olympiad, a professor told us to practice computing ability in this way: when brushing the questions, first look at the practice answers, find the kind of answers to do more calculation process, in addition, pick the kind of questions that require calculation skills to do, for example, some geometry problems can be used in the calculation process can use some small tricks (because the notes of the Olympiad are not good to take pictures at school to give you examples) The calculation process must be focused and serious, not half-hearted and impetuous, Determination and tenacity to persevere are almost enough.

Train. This practice is not to find an oral arithmetic book to practice like elementary school students, but to strengthen the calculation ability in the usual exams and homework, do not rush to find a calculator when encountering calculation problems, and pay attention to the usual accumulation. Examine.

What to look for? Fill in the gaps. I have found that many high school students are weak in multiplication and division, especially division.

For multiplication, we can use the 19 19 multiplication table to do it, for division, many students are at a loss, my suggestion is, use more fractions, more divisives.

Personally, I think we can only rely on practice, our math teacher has also mentioned to us about the improvement of computing ability (I am a sophomore dog in high school), you can buy the kind of calculation problems that primary school students do, such as multiplication and division within a hundred, etc., after all, what you want to improve is computing ability, and it is the key to grasp the foundation, don't think that the questions of primary school students are useless.

Do basic calculation exercises, from brackets to perfect square formulas, from logarithmic exponential operations to trigonometric function deformation, from conic curve convincing to space vector operations, there are many basic calculation problems on the Internet for you to practice, do it patiently one by one, be sure to ensure 100% accuracy at the beginning, and then increase the speed, if the mind can't calm down and can't focus, just change the time.

The only way to improve your computing ability is to see a complex calculation and don't run away from it, just do it and get familiar with it, buy a calculation card to practice, there is no shortcut to improve your computing ability, you can only do it step by step, and improve your proficiency.

My conclusion is that "slow is fast", and slowing down the speed of solving problems can improve the accuracy rate. During the exam, sometimes you can write two big questions in 5 minutes, but sometimes you can't write a difficult question in 20 minutes because it is difficult. But those two big questions didn't get a full score because of quick calculations, and then the puzzle didn't go without a score, isn't it hurt?

I have always written the first two big questions slowly so that they are correct, and I can get the first score if I can't solve them later.

Clause.

1. Memorize various calculation rules.

As parents, we certainly think it is very simple to do arithmetic problems for elementary school students. However, for children who are in elementary school, the various rules of arithmetic can be a big challenge for them.

Simple addition and subtraction calculations are fine, but when it comes to mixed operations, the rules are relatively complicated, and many children feel stupid and can't tell the difference.

Memorizing the calculation rules of various types of questions is an important guarantee for children to not lose a single point in their calculations. If you don't even have a good grasp of these basic algorithms, what can you do to expect a high score? Of course, these rules should not be memorized by rote, and the most important thing is for the child to understand why they are doing it.

Clause. 2. Summarize and analyze the calculation methods.

It is not enough to memorize the calculation rules of various question types, because the rules are only a textual overview, and students need to correctly apply these concepts to the calculation question types in order to increase the score.

Many children lose points when calculating, because the summary and analysis of the question type on weekdays is not enough, after getting an unfamiliar question type, the teacher explains the answer and steps and it is over, few students will make an important mark, take it out when reviewing. As everyone knows, the summary and analysis of these question types are an important guarantee for me to calmly cope with various operations in the future.

Of course, when parents help their children with homework, they should not only care about the right or wrong answers, but also be careful to see what the reasons for the child's mistakes are. If it is the child's first time to come into contact with similar question types, parents must be more patient when tutoring and teach the child the idea of calculation and what the correct steps of calculation are.

Clause. 3. Strengthen the practice of various types of questions.

It's not enough to memorize the concepts, and although I don't advocate the tactics of the sea of questions, the necessary exercises must be completed.

In the process of practicing, it can not only help children sort out and summarize various question types, but also correctly apply the concept of words to it, in fact, the vast majority of children make calculation errors because they are not proficient enough in the question type or do not have a firm grasp of the calculation rules and steps when calculating, and appropriate practice can quickly solve these problems.

Of course, in the process of practicing, the question type should not be too simple. We can make one or two of all the calculation questions that children have learned, so that children can consolidate the knowledge they have learned while learning new knowledge.

Many children can always get everything right when they practice separately, but when they encounter a comprehensive summary such as a test, the child's lack will immediately become apparent.

Allowing children to summarize the reasons for their mistakes and find ways to improve in the process of practice is the key to allowing children to grow up quickly.

After understanding the principle, I am brushing some questions, and basically high school no longer tests the calculation ability of mathematics, but the comprehension.

Alas, this question is simple and complicated. In fact, for high school students, it should not be so-called"Computing power"Problem! If a high school student has poor numeracy skills, it can only be said that he did not lay a good foundation in junior high school!

If you are a high school teacher, I recommend that you force your students to practice their junior high school knowledge within a set amount of time (in fact, there is not much spare time in high school). --This is just a suggestion, but the actual effect is not necessarily ideal. I don't think this kind of student with poor numeracy skills is hopeless.

Throw away the calculator! Every time you do a question, you must be careful and serious! It must be taken seriously psychologically!

Also, the use of straw paper is very important!! Be sure to develop a good habit of calculating each piece of straw paper from the upper left corner, and arrange the use of straw paper reasonably! The computational thinking process is clear and neat, and it also avoids the trouble of repeating multiple calculations.

This makes it easier and more effective to check your own rough calculation process!

The first is, of course, to be careful, not to be sloppy.

Second, in the usual homework, we should try to improve the efficiency of hand arithmetic, in the exam can be fast and third, practice makes perfect, math problems to do, questions to do, everything is a trivial matter, this is my own point of view, I hope it will help you.

Numeracy is a basic skill that every secondary school student must master, but in the course of daily teaching, we find that students' numeracy skills are generally poor. Many children lack basic calculation skills and good calculation habits when calculating, and always think that it is "sloppiness", "carelessness" and "lack of attention" that cause calculation errors, lack of attention, and the success rate of students' calculations is low. So how can you improve your students' numeracy skills?

1. Analysis and Reflection External reasons: 1. The reform of the junior high school curriculum has weakened the arithmetic requirements; 2. The widespread use of calculators weakens the sense of calculation; 3. Teaching concepts such as student burden reduction and happy education hinder the healthy development of students' computing ability; 4. The teacher's teaching intensity on arithmetic is insufficient, and the math problem is focused on ideas and light on arithmetic. Internal reasons:

1. Do not pay attention to knowledge reserves, do not pay attention to the foundation, and do not pay attention to the induction, reflection and summary of mathematical ideas and methods 2. The concept is ambiguous, and students are prone to miscalculation due to vague concepts. 3. Inaccurate memory of formulas and properties 4. Poor data processing ability (calculation, sorting, screening, classification discussion, etc.) 5. Poor mathematical language, resulting in poor reading habits, poor reading ability, and no way to start arithmetic 6. Lack of awareness of testing, reflection and summary of operation problems· 7. Poor ability to express questions carefully 8. Poor arithmetic habits, eagerness, and rough branches. Which got me thinking? How to teach students according to their aptitude and person-oriented according to their actual situation, take corresponding countermeasures, and consciously train and cultivate.

To enable students to master basic computing skills and have good calculation habits, so as to help students improve the accuracy of calculations? 2. Problem-solving strategies 1. Insist on doing (2-3) calculation problems every day; 2. Do questions within a limited time; 3. Standardize the question, no skipping; 4. Use good scratch paper; 5. Correct the wrong questions and analyze the reasons for the errors; 6. Use concise and reasonable methods to do calculation problems, so as to improve the accuracy of one-time calculation; 7. Improve students' problem-solving speed and problem-solving ability; 8. Cultivate students' good problem-solving habits and interest in learning mathematics;

Mathematics is a compulsory course for every student in primary and secondary schools, and mathematical computing ability is a basic mathematical ability, which is not only an important foundation for mathematics learning, but also a necessary skill for students' future life and work. However, the numeracy ability reflected by today's students in learning is worrying, and there are often calculation errors, and students' numeracy skills are generally poor, which directly affects mathematics performance. If students want to learn mathematics well, they must first learn to calculate well, and the level of computing ability greatly affects the learning ability of mathematics, and how to improve students' computing ability is a common problem faced by teachers.

Combined with my own teaching practice, I believe that we should divide the following two different situations and take different countermeasures to improve students' numeracy ability.

First, it is not a careless problem, some calculation rules have not been mastered, and the foundation is not solid enough.

Many students, including parents, think that the calculation problem is just a careless problem, but it is not. Some students may not have a good foundation in arithmetic in elementary school, and it is difficult to add, subtract, multiply and divide, and even make repeated mistakes in junior high school. Sometimes the calculation problem is far more than a careless problem, it may be that the students addition, subtraction, multiplication and division of the four mixed operation rules are not clear, it may be that the multiplication formula memory is not accurate, the root cause of the problem is uneven, therefore, first of all, it is necessary to do a comprehensive survey of students to understand what problems they have in the calculation, and then targeted tutoring, aiming at the source of these calculation errors, prescribing the right medicine, so that the medicine can be eliminated, reduce the calculation errors, and gradually improve the calculation ability.

Second, there is no problem with the basis of calculation, mainly carelessness leads to calculation errors.

Of course, many students recite multiplication formulas, and the mastery of the four rules of operation is no problem, most of these students' calculation errors are caused by carelessness, and I generally suggest this part of the students: 1. Strengthen the training of arithmetic skills, practice more and sometimes do not choose the right method, and the problem that can be calculated in a simple way is complicated, which naturally leads to a great increase in the error rate. 2. Strive to develop good computing habits.

For example, students who don't like to write drafts can find special scratch paper and write drafts seriously, and students who do not have the habit of checking strive to cultivate the habit of checking. When people, each student's situation is different, many times I also ask students to do some calculations directly in front of me, so that they can see the problem more clearly, solve the problem in a more timely manner, and directly improve the accuracy of doing the problem.
