Mathematics is a very weird subject, and there is a phenomenon of "echelon behind". It's not that your knowledge of the lower grades has been learned, and the knowledge of the upper grades must be learned well.

  • What is a run-off? In mathematics, we often see that in the third and fourth grades of elementary school, a group of students 'mathematics scores suddenly fell down; and then, when the second and third grades of junior high school, often a group of students' mathematics scores fell behind; Later, when high school was still in place, there were still people left behind.

Many educators try to explain this strange phenomenon. Some people say that "the child is old and disobedient", some people say that "adolescence, the child is wild", and some people say "there was no thinking training as a child".

I agree with the last statement, more precisely, that the foundation of thinking ability is not solid.

Mathematics is a high-level thinking activity of human beings. The more you go to the top, the more various thinking abilities you need. When the thinking abilities are insufficient, it is inevitable to fall behind.

For example-before the third grade of elementary school, mathematics only needs memory, and remembering some calculation rules will work;

But in the fourth grade of elementary school, it is not enough to have memory, but also logical ability. At this time, children who lack logical thinking ability are left behind;

By junior high school, we still need spatial imagination, and students with insufficient spatial imagination can't run;

In high school, thinking skills such as abstraction, induction, and deduction may be used. Students with insufficient comprehensive ability in this regard will be unable to do so.

This is a bit like laying a foundation to build a tall building. The deeper and stronger the foundation laid in childhood, the higher and more majestic the building will be in the future, and the less you will be left behind.

Therefore, if you want your child to be good at math, first help him "lay the foundation".

How to lay the foundation?

How to fight the foundation? I personally think there are three: one is the development of eight kinds of intelligence; the other is the enlightenment of life mathematics; the third is to cultivate reading interest.

● Development of eight kinds of intelligence

The so-called eight kinds of intelligence are described by Dr. Gardner in the United States. He said that human intelligence is diverse rather than singular. Cognitive intelligence, natural cognitive intelligence and other 8 components.

How to develop eight kinds of intelligence

1. It's very simple, just let the children play, the more crazy the better.

Shout and talk in the game, this is called language intelligence;

Combine multiple game items and calculate the number in the game. This is called computational intelligence;

In the game, climb the tree and jump down to pile up the blocks. This is called space intelligence;

Run wildly in the game, this is called sports intelligence;

Cooperate and coordinate in the game, this is called interpersonal intelligence;

In short, the more crazy the child is and the heavier he is, the better these eight kinds of intelligence are developed, and the better the math performance in the future may be.

2. Ask the child to find the "King of Children".

What is the "King of Children"? Those who are particularly active and excited, and who can and are willing to play with a lot of children, are called "Kings of Children".

This kind of child is often born and can't be cultivated, so if you meet him, don't let it go, you must find a way to get close.

Because only in this way can children play hi, so the eight kinds of intelligence have been exercised and developed in the subtle way.

● Mathematical Enlightenment in Life

Ever watched Yin Jianli's "A Good Mom is Better than a Good Teacher"?

She said that her child started at the age of 4 and started to learn math through games. Within two years, he would be able to add and subtract within 500. What they played was a simple game, “Open a small store”, and let her be a counter around a place, put something, and her parents took turns to buy.

Real pricing, real money, real change, playing around, these money calculations have become a natural "application problem" training. After training in the second grade of this kind of elementary school, after the school passed the test, I didn't think it was necessary to go to the third grade either. She jumped directly to the fourth grade.

That's right, the daily trading activity in life is actually the best mathematical enlightenment.

Examples of daily trading

If we do n’t know how to play the “commissary”, it ’s also a good way for a child to go to the supermarket to buy his own toys or buy ice cream and let him calculate, take, spend, and save money.

Or, play hard, and give all the tasks of buying food, smoking, and household items to children 5 to 6 years old before going to elementary school, and be a full-time family purchaser.

Of course, this game requires the cooperation of parents to be able to play, and it also needs to adapt to interests and timing.

Also, throwing dice, playing poker, and participating in the children's flea market are all methods; the specialty is Montessori's math teaching aids, and everything can be done in the game.

Anyway, every day you always have to face children, and every day children have to haunt you to play. If you do n’t know how to play, then play “mathematics games”, think about it, and combine abstract numbers into the game. Think of pocket money as a prop.

As you play, it is estimated that the addition, subtraction, multiplication, and division of the third grade of elementary school will be completed for you, and there is still a little pressure, and it is also cheerful and interested.

● Develop reading interest

Some time ago I saw an article, "Reading is the best" make-up lesson ", saying that the children's math scores are not good, and the root cause is that they don't read too much? This principle is 100% agreed, and an excerpt from that article is as follows:

A few days ago, a friend recommended a math tutor to my 13-year-old daughter. "What's the situation with your child's maths?" The teacher asked me briefly in a few words on the phone.

"The problem is not difficult and the grade is good. Whenever I encounter a problem, it seems like I can't go deeper." I have a headache when it comes to my daughter's math.

"So does she usually like to read?" The teacher's question made me startled. Isn't this a matter for the Chinese teacher? With mathematics. . . ? "I don't particularly like it, but I don't read it at all. I usually like watching" Naughty Pack Horse Jump "or something like that." I thought about it.

"Oh, have you read the science books and some classics?" The teacher asked. "No, I don't understand books that I think are useful for studying, and she is unwilling to read them." I replied a little embarrassedly. "There are some problems," said the teacher. "If children want to learn mathematics and physics in junior high school, they must read more in elementary school, especially good books with deep humanities. Children who read more good books have active thinking and vision. It ’s broader, and by the second day of the year, it will show more advantages. "

"Most of my classmates with good grades in math can read books when they are 6 or 7 years old. In elementary school, they read a lot of good books with profound humanities. They love thinking and reading. The depth and breadth of this group of children sometimes ask me It's stumped.

And most of the children who do not perform well have not read any books before, and now they do n’t like reading. Some of them do n’t like oil and salt. There will be much improvement. "

After hearing what he said, I suddenly remembered that Soviet educator Suhomlinsky once said in "Advice for Teachers": "The more students study, the clearer their thinking and the more active their intelligence is. "

The importance of reading to mathematics

Many parents always feel that the changes brought about by reading are very slow, and the exam is just in front of them, so they still feel that it is not as direct as supplementary classes, and the effect is more significant.

Today, after a reminder from the math teacher, Moseton opened. The effect of reading is not only to enrich cultural accumulation and improve language literacy, but also to help children ignite the spark of thinking, expand their horizons, deepen their thinking, and improve their learning ability.

Therefore, reading is not just a matter of language. It is a priority for any subject. Studies have found that children who read a lot in the first grade or earlier have greater potential than children who start reading in the third grade in subsequent elementary and secondary schools, especially in mathematics, physics and chemistry.

Because the former has deep reading ability and habits in the subsequent study life, that is, strong understanding ability, while the latter has superficial thinking when reading, and the understanding ability is naturally weak. This phenomenon is evident in the watershed grade of the second grade.

So, do n’t wait until the elementary and middle schools encounter difficulties to endlessly make up for lessons. Instead, let your children solve the literacy problem when they are 4-7 years old. They will love reading when they are 6-9 years old, and read a lot after 9 Read a good book.
