6 ways for your kids to improve their numeracy skills

I\’ve been working for three days and it\’s only Tuesday. Where can I go to reason? Many things in the world are unreasonable, and children\’s test papers are also unreasonable. There are often many inexplicable errors, such as 13+38=41. Asking questions means you are careless. But this kind of mistake is really not carelessness, but the essence is poor calculation ability. The four words computing power, to put it bluntly, mean calculation speed and high accuracy. The problem is that calculation speed and accuracy are naturally contradictory. A common problem among most children is that they tend to make mistakes if they calculate quickly. The exam happens to require as much accuracy as possible within a limited time. So the most common situation is that questions that you normally do will make mistakes when it comes to the exam. In mathematics examinations in primary and secondary schools, except for a small number of proof questions, all other questions are inseparable from calculations. If you want to get high scores, calculation ability is the decisive factor. Just look at last year\’s college entrance examination mathematics questions. You can say that the questions are difficult. If the test time is extended to four hours, many children will be able to answer almost all of them correctly; but in the case of only two hours, the calculation Students with weaker abilities are likely to end the exam without even finishing the questions. There are even situations where the top players in the competition only take more than 130 points. Let’s get into today’s focus and talk about ways to improve computing power.

Some people\’s approach is to let children practice hard, such as practicing 100 calculation problems every day. If the child is patient, this method will certainly be effective. The problem is, most kids are intolerant of chicken, so this approach is questionable. When children are very young, especially in the first and second grades of primary school, calculations are relatively simple and take a short time. It is still feasible to do 100 calculation problems. But if you reach the upper grades of elementary school and the calculation of fractions and decimals appears, doing 100 tasks is a bit too much. Calculation is a purely physical activity. Doing too many calculation problems will bring negative feedback to children and make them bored. The feeling of doing 100 calculation problems is like Sisyphus in Greek mythology, pushing the stone over and over again. It feels torture just thinking about it. In the countryside, when a donkey is asked to grind, everyone knows to cover the donkey\’s eyes, otherwise the donkey will get bored easily. If a donkey is like this, how can people be embarrassed? Calculations in the lower grades of primary school are relatively simple. You may be able to practice 100 additions, subtractions, multiplications and divisions every day, but a better way is to practice them randomly during leisure or walking, such as casually asking questions such as how many minutes there are until ten o\’clock in the evening, and Kids game calculation. When practicing calculation skills in the upper grades of elementary school, middle school and high school, don\’t just practice calculations. That\’s too boring. You should combine them with the questions. Most math questions come with calculations. When doing the questions, don\’t just list the calculation formulas. You must also ask for the answer to the last step. It is a good idea for advanced students to practice calculations while solving problems, because they will not easily get bored. ◈Method 2: Establish the concept of doing homework once and for all. The calculation seems simple, but in fact it is determined by many subtle habits that determine the result. When doing calculations, you must pay attention to theseHabit. However, if children subconsciously think that this is just homework and mistakes can be corrected, they will inadvertently develop many bad habits, which will also be affected by these habits during exams and cause simple calculation errors. The correct approach is to be accurate first and then fast in your daily homework. It is better to be slower than to make fewer mistakes. You must not reduce the accuracy rate for the sake of speed. ◈Method 3: Develop a good habit of clear steps and neat scratch paper. One trick to improve accuracy is to write the steps strictly and write each step clearly. Don\’t omit steps even if you remove the parentheses. Over time, the accuracy will naturally increase. The premise that practice makes perfect is to be familiar with it first, and don’t think about entering the skillful stage directly. The purpose of keeping the draft paper clean is to facilitate inspection. When doing many calculation-intensive questions, especially analytical geometry and sequence calculations, it often happens that you realize that you must have made a mistake at a certain step. At this time, a neat draft paper comes in handy. Once it is put to use, it will be easier to find the problem when you turn around and go back to check. ◈Method 4: Write common mistakes on sticky notes to remind yourself. Everyone has his or her own mistakes. For example, when I was in junior high school, there was a time when I often lost one term when multiplying cubes of polynomials. In order to remind myself all the time, I wrote it on a small piece of paper and put it in a prominent place. In the end, every time I see a similar problem, I will say in my heart \”Never lose an item\”, and the number of mistakes will be much less. ◈Method 5: Try to memorize the basic calculation conclusions. No one can make mistakes in calculations like 1+1=2, mainly because this is already a mechanical memory. For senior students, the multiplication tables and addition and subtraction within 10 have become mechanical memories and are basically error-free. If you can memorize some frequently used conclusions, it can also work wonders. At the primary school level, these conclusions mainly include prime numbers within 100, multiplication of numbers within 20, etc., and of course the more controversial square tables. In middle school and high school, trigonometric formulas such as squares, squares and squares, and binomial squares and squares must be memorized. Square tables are actually very useful, and Thie Cha strongly advocates memorizing all two-digit square tables. My opinion on this is: If you can memorize it, it is certainly very effective. For example, if you can calculate 73*77, children who cannot memorize square tables can only calculate vertically. Children who cannot memorize square tables can use 75*75-4=5625- 4. It’s easy to figure out the answer. Don\’t underestimate the calculation time saved. In exams with a lot of calculations, saving a little more time can improve your scores a lot. Therefore, if you cannot memorize all the two-digit square tables, at least the square tables within 20 should be memorized. ◈Method 6: Focus more on the basics and less on skills. The improvement of computing power is a process that practice makes perfect. The oil seller\’s ability to pass oil through the copper coin hole is the result of thousands of practices and does not involve any special skills. However, in this era of quick success and instant benefit, many people blindly pursue quick success, hoping that they can become a master by learning a trick. In fact, most simple calculation techniques are useless because they require harsh conditions for use. Apart from being fancy and good-looking, they are rarely used in exams.arrive. Of course, not all techniques are useless. For example, the square difference formula mentioned above is very useful. Other rounding methods can also improve the calculation speed. But as long as the child often does calculation problems, the rounding method is actually a matter of course. the process of. My suggestion is that in elementary school, you should strictly follow the methods in the book when doing calculation problems, and think less about little tricks that can simplify calculations. You’ve all seen this, give it a thumbs up and go away. Let’s enter math time. Today’s thinking question is a geometry problem. The knowledge used to solve the problem is no more than the second grade of junior high school. This question is only for competition students. Students who do not plan to participate in the competition should ignore this question. Thinking question (difficulty level 4 and a half stars): Draw any n circles on the plane so that the center of each circle is outside the other n-1 circles. To ensure that no matter how you draw a circle, you cannot find a point that is inside all circles at the same time, what is the minimum n?
