Chinese seem to have an obsession with "arithmetic" (not arithmetic), for example, parents are very happy to see their children can multiply multiple numbers, thinking that their children are "good at mathematics", and I remember that many years ago, there was a Mr. Shi Fengshou who specialized in teaching speed algorithms was once popular, and now he is the "Chinese rain man" in various "mental arithmetic" and "strongest brains". In fact, all this is nothing more than setting a "benchmark" that ordinary people can understand. If you don't believe it, you can watch the "Poetry Conference", which compares memorization rather than creative ability, and the mathematical performance of this benchmark is numerical calculation. I think Shi Fengshou's speed algorithm can be seen and understood by a math enthusiast like me, who has no academic pursuits, but it is too cost-effective to really treat it as a technique that requires repeated practice - even in the era when he was popular all over the country, China already had calculators, and it was too much trouble to memorize his formulas in comparison. So, what can be done to improve computing power?
1. Several important reasons for poor arithmetic
Mistakes caused by knowledge acquisition deficiencies
Only on the premise of a deep understanding and firm grasp of the basic knowledge of concepts, properties, arithmetic, laws, and laws in primary school mathematics can students correctly and flexibly apply them to form computing skills. Due to some knowledge not understood, unclear concepts, not really understanding arithmetic and mastering algorithms proficiently, not having a good grasp of calculation rules, concepts or operation sequences, etc., students will make mistakes in calculations, and students themselves do not realize that they are wrong.
Children learn by death and don't know how to do it
Sometimes children do not learn math well because they have a low IQ and are not strong in logical thinking. On the contrary, they have not been rewarded for their efforts, and some children listen very carefully to the lecture during class, but they may be busy copying the teacher's notes at that time, and they have no intention of caring about the next knowledge point that the teacher will tell. When learning is not efficient, the gain is often not proportional to the effort. This also proves that if children usually learn mathematics, there is no good way to educate them, and they often get half the result.
In the long run, children will become less and less confident, suspicious of the world around them, lack of decisiveness in doing things, and always think twice, so no matter what things don't go well outside, parents should not bring emotions to the home!
Second, several ways to easily improve arithmetic ability
Turn learning mathematics into concrete feelings and experiences
Primary mathematics is the foundation of mathematics education and is the beginning of a child's lifelong learning of mathematics. How to show a colorful and closely related mathematical world in front of children, make abstract and boring mathematics vivid and interesting and intimate, so that children love mathematics from the bottom of their hearts and take the initiative to use mathematics. I think the key is to strengthen the connection between mathematics and life, turn abstract and unfamiliar mathematics into concrete feelings and experiences, and bring mathematical knowledge to life. Modern research in child psychology has shown that when children learn mathematics, their mental activities cannot be supported by concrete things. Moreover, the learning of primary school students has a strong sense of color, and they feel kind and interested in familiar life situations. Only when mathematics is no longer a straight face, but is closer to the reality of children's lives, will they have an interest in learning, will they enter the role of learning, will they truly feel and experience the charm and value of mathematics, and enhance their confidence in understanding and application. In teaching, attention should be paid to starting from the life prototypes that students are familiar with, evoking their existing life experiences and feelings, and making learning a demand from the bottom of students' hearts.
Split term method
In children's primary school, the calculation of scores is a difficult knowledge point. When parents tutor their children to do fraction calculation problems, they can let their children try to use the "split term method" to solve the problems. The split term method refers to the reasonable splitting of each item involved in the fraction formula, so that the split items can cancel each other out. A common method used by children is to split the fraction into two or less fractions, the sum or difference of two or fewer fractions. Therefore, when instructing children to use this method, it is necessary for children to learn to observe carefully, so as to find the key point of solving the problem, that is, the part shared between the numerator and denominator in the fraction equation, so as to facilitate simple calculations. The common formula for this is:“1/n(n+1)=1/n-1/n-1”。
Strengthen the basic training of oral arithmetic
As the saying goes: "practice makes perfect", in order to improve the ability of oral arithmetic, we must do a good job in the basic training of oral arithmetic, do more, the response will be fast, the accuracy rate will be high, on the contrary, the reaction will be slow, the accuracy rate will be low. For basic oral arithmetic, such as: addition and subtraction within 20, it is necessary to train repeatedly to achieve proficiency. The oral arithmetic of carrying and abdicating within 20 is also the key training content.
Toys that are truly suitable for children are more conducive to stimulating and promoting the development of children's motor coordination, cognition and brain thinking.
I recommend a new toy that I recently discovered, and the children at home especially like to play, that is, this child's math enlightenment artifact——Puppy arithmetic scales.
The most important thing for a good toy is to be fun, so that it can arouse the interest of children and continue to play.
We don't expect toys to develop geniuses, children are willing to play, make the learning process fun, and get a sense of accomplishment from it, which is the most valuable.
The puppy digital balance is a toy that allows children to fully feel, try and make mistakes, and then find the right answer by themselves.
Learning through play is very fun.
The shape of the puppy itself is very popular with children, and the design is particularly ingenious, and the weight between the number and the puppy is very accurate and error-free, which is not possible with other similar balance toys.
If there is 1 more, the balance will be immediately visualized, telling the child that it is not equal, she can easily understand the concept of 3.
Not only do numbers and puppies create a balance, but so do numbers and numbers.
There are also matching cards for children to practice together, which can deepen the memory of the baby's logarithmic sense.
There are many ways to play, learn math while playing!
01. Let children know numbers.
Bao Ma can put a number on one side of the scale, and let the child choose the number or put the puppy on it
By balancing the scales, children will gradually understand the connections between numbers and quantities.
02. Let children learn to compare the size of numbers.
For a child who doesn't know much about math, suddenly telling her that the numbers 8<10 are difficult to understand.
However, by comparing the size of the scale, the child will naturally learn the size of the number after playing well.
03. Let children easily learn addition and subtraction.
Put an 8 on the left side of the scale and a 3 on the right side and ask the child to think about what 8 minus 3 isOr how much 3 plus equals 8.
In the process of testing, it can not only cultivate children's mathematical ability, but also cultivate logic in the process of thinking.
04. Make digital cards as a parent-child game.
In addition to using the balance to do addition and subtraction, you can also use the cards that come with it to play number games.
Draw a random card and use the other cards, numbers, and puppies to complete the content behind the equal sign.
Phased play Cultivate children's interest in learning in an all-round way.
The difficulty of the cards ranges from green to purple to blue, allowing children to play in stages without skipping steps.
Because it is advanced from shallow to deep, it is also more in line with the child's cognitive development level.
The most practical thing about this set of cards is that it saves mothers from racking their brains to think about the topic.
There are many different combinations of addition and subtraction problem calculations, which can be played in turns and can be played for a long time.
05. Two-player or multi-player game.
One person is responsible for the left side of the scale, one person is responsible for the right side of the scale, one person is responsible for solving the problem, and the other is responsible for leveling the scale.
If there are more than two children in the family, this game must be fun.
Compared with the textbook-style graphic teaching method, this way of touching and trying is more suitable for the thinking mode of young children, and the time that can be played is also very long.
Each number has also been carefully handled, and the size and weight are suitable for the child's palm.
The size of the puppy is small, so if the child is still relatively young, I am afraid that the naughty baby will put it in the mouth and eat it by mistake, so the younger children also need to be accompanied by adults during the play.
In addition to the puppy arithmetic scale, there is also a small monkey scale, which is also very cute!
This set of arithmetic balances was originally only listed abroad, a set of more than 100, but now we also have our own domestic production, a set of **699 yuan, decent, 2 sets**119$9
This arithmetic balance allows children to play from the age of 2 years old and easily learn math and arithmetic while playing!If you like it, don't miss it, and remember to start math as soon as possible
