In another month, another group of children will go to primary school, and many parents have begun to warm up and prepare for their baby's sprint.
A few days ago, Longlong's mother complained that she had a little trouble: the connection between young people has ended, but now math addition and subtraction are always wrong, 2+5 = 7, 2+6 or even 7, but 3+6 can equal 9 again ... She took her children to practice over and over again, but the accuracy is still like a roller coaster. I really don't know what the problem is.
As a person in the past, I understand the anxiety of parents like Mama Longlong. After all, establishing a good relationship between children can help children quickly adapt to primary school life and build self-confidence. However, letting children do the same thing before going to school will put them in a state of mechanized learning and produce resistance. Therefore, we really need to find an appropriate way to solve this problem.
According to Earle's cognitive development theory, children aged 2-7 are in the pre-calculation stage of cognition, and the learning of knowledge and concepts needs to be confirmed through perception.
Children in Grade One are about 6-7 years old. At this stage, they don't study math and calculation like us. They understand that they are codes and symbols, and also understand their corresponding meanings, and then substitute the numbers into the calculation to get the answer.
In the eyes of preschool children, a solid apple, a finger and a dot are all objective objects. Another time, it represents abundance and abundance. It needs to be tested and counted through specific events. 2, they can't directly understand at this time? 1 + 1 = 2? .
Do you understand? 1 + 1 = 2? The best way is to practice and understand in life experience and games? 1 + 1 = 2? Different types of apples, and then learn the meaning of eliminating the object itself. 1 an apple and an apple are two apples, which means that one plus one is more conducive to the improvement of children's computing ability.
Addition and subtraction are computing power. If you want this ability to develop well, you must first have it? Digital meaning? And then what? Digital meaning?
The first is to understand the relationship between quantity and quantity. I remember last year when my son just went to primary school, his math performance was even worse. When I play games with him:
Me: Count how many?
Duo:1.2.3.4.5,5! It's good. How's this? 1.2.3.4.5.6、5!
Me:
This kind of feedback made me realize that my son knows how to count, but he doesn't know the corresponding relationship between quantity and quantity. At this time, he naturally can't cope with a higher level-calculating. Addition and subtraction, if forced, run counter to children's cognitive development, which will only bring pressure to children and destroy their self-confidence and learning motivation.
How to determine whether there is?
As long as you follow the above instructions, you can live with your children. If children can finish their studies smoothly and accurately, that's fine.
(The same is true for children before the first grade. They don't have to wait until the first grade to go to school. )
The addition and subtraction of pure arithmetic is an abstract concrete operation. The direct contact with the first-grade children exceeds his cognitive level, and those children who improve their ability to brush questions rely more on memory storage. Such children will lack application skills in the future, so be prepared?
5 can be divided into 1 and 4. Many children can remember it, but they must pay attention to the connection with the real thing. Take out ordinary things, let children count, constantly perceive, and form the connection and knowledge between applications.
? ,? = means you can draw symbols, and then let children represent numbers with objects and execute equations. In this process, you also have to count, and then gradually replace it with numbers. Please note that the+and-symbols should be used to get children into Piaget? Specific calculation stage? The reverse thinking (such as the reverse thinking of addition and subtraction) laid the foundation.
Addition and subtraction exercises should be based on experience and can be completed in life, games and tasks (problems). Recommend some common games:
1. Finger Game
Many parents will stop and even blame their children when they see them calculating problems with their fingers. This is actually wrong.
Fingers are children's natural calculators. Bring the child to him, and he will think of this tool and use it when he encounters calculation difficulties. This in itself is the embodiment of problem-solving ability and needs to be liked. At the same time, numerals refer to the process of establishing quantitative relations. When children count to a certain extent, they will naturally understand the meaning of calculation.
Therefore, we must encourage children to use their fingers more and help them build confidence in mathematics.
When I solve my son's calculation problem, I usually use several small games:
There is a nursery rhyme 10, practice closely.
19 19 good friend,
Hand in hand,
Three seven three seven is really close.
4646
Fifty secondhand.
We can combine nursery rhymes with children for finger interaction. For example, among the good friends of 19 19, one person got one and the other got nine, which is very close to the form 10.
It should be noted that when you loosen your fingers, you must change hands after 5 or more fingers. Why? Because this can form a 10 hand picture in the child's brain, which is also very helpful for separation and memory. /kloc-numbers below 0/0.
Actually, this is our wine list. The fist represents 0, the palm represents 5, and the reciprocal is 32 1. Say your total together, is it 0, 5, 10, 15 or 20? The rewards and punishments for right and wrong can be agreed in advance, and you can get stickers, draw stars or other things.
This is mainly to practice arithmetic such as 5, 10, 15, 20, which is the basis of arithmetic. Relatively simple, this is a good foundation for children to learn addition and multiplication in the future.
When I was joking with my son, it was accidental. Later, I studied the principle and found that it was a good transition from physical calculation to abstract calculation, similar to the abacus in children's minds at the beginning of abacus calculation.
Son: If mom takes the exam, can I?
I can.
Son: What if it exceeds 10?
Me: When I was a child, I used my feet. ...
Son: How to use it?
Me: imagine it will be as flexible as a hand, not a mother's hand, and then use your little hand to calculate.
Remember, it's a son He smiled and leaned forward and backward, then stretched out his foot and began to count. Later, he began to try to put his finger on his head (the basic ten methods are very helpful), and combined with several other games, it can be easily realized without fingers? Freedom of calculation? .
Perhaps in the eyes of parents, playing cards is an unpleasant thing. In fact, it is also a powerful tool to realize the freedom of operation.
What is the most effective? 2 1? This is also what many children like.
The rules of the game are: 1- 10 stands for their respective numbers, and JQK stands for 10 (don't be king). Everyone takes turns to count the total number of cards in their hands. The person with the nearest 2 1 card and no more than 2 1 card will be regarded as the winner.
In this game, practice is constantly added, because it has a certain stimulating effect, which will promote the child's brain to be in an excited state and make the brain more active. This kind of exercise with high brain activity has better effect.
3. The bottom line of life:
Apply what you have learned? Let children feel valuable and stimulate their inner learning motivation, which is the key. In life, children should be exposed to computing content, increase exercise opportunities and enhance their self-confidence.
For example, you can calculate the change when you buy food, the price difference when you leave the tableware at home, the type and quantity when you share it with everyone, and so on.
I'll play? Scum? My son took it for half a year, and through the game of counting hands and feet, I stood out from the slag that was never equal to 5 in primary school. I successfully attacked Xiao Zhu, and I can not only add and subtract when I am 20 years old. He also volunteered to learn the vertical addition and subtraction within 100 (the verbal card he got from his sister), which changed from five and a half years to five and a half years.
Every child has his unlimited potential, and play and trust are the best boosters. Take the children to move. I believe that your children can also become happy arithmetic masters.
