Primary Mathematics Grade 4 Mathematics Tabloid Information

The content of the fourth-grade mathematics tabloid includes the sorting of easy-to-mistake questions, the review of key content, and the sorting of example problems. It can be used in the form of hand-copied newspapers, computer prints, scraped newspapers, etc.

Math tabloids are more demanding and difficult, and students are best off completing them with their parents. However, we should not use the knowledge we have learned, and do not blindly and rigidly imitate the old-fashioned form.

The content of the math tabloid

Since then, I have consciously connected mathematics to everyday life. Once, my mother made cakes, and I could put two cakes in the pot. I thought, isn't this a math problem?

It takes two minutes to bake one cake, one minute to bake the front and back sides, and a maximum of two cakes in the pot at the same time, so it takes a few minutes to bake three cakes at most.

I thought about it and came to the conclusion that it would take 3 minutes: put the first place.

1. Put the second cake into the pot at the same time, after 1 minute, take out the second cake, put in the third cake, and turn the first cake over; Bake for another 1 minute, so that the first piece of bread is ready, take it out. Then put the reverse side of the second cake and turn the third cake over at the same time, so that it is all done in 3 minutes.

I told my mom about the idea, and she said that it wouldn't be that coincidental, there had to be some error, but the algorithm was correct. It seems that we must apply what we have learned in order to make mathematics better serve our lives. Mathematics should be learned in life.

Some people say that the knowledge in books has little to do with reality. This shows that their ability to transfer knowledge has not been fully exercised.

It is precisely because of the inability to understand and apply it in daily life that many people do not pay attention to mathematics. I hope that students will learn mathematics in life, use mathematics in life, mathematics is inseparable from life, learn deeply, learn thoroughly, and naturally find that mathematics is actually very useful.

The content of the 4th grade math tabloid is written as follows (using a number story as an example):

1. The smallest number.

The ancient and large family of natural numbers is made up of all natural numbers and so on. The smallest of them is "1", and the largest cannot be found. If you're interested, look for it.

Second, there is no maximum natural number.

Maybe you think you can find the largest natural number (n), but you immediately find another natural number (n+1), which is greater than n. This means that the largest natural number can never be found in the family of natural numbers.

3. "1" is indeed the smallest of the natural number family.

Natural numbers are infinite, and "1" is the smallest of natural numbers. Some people objected that "1" was the smallest natural number, saying that "0" was smaller than "1" and that "0" should be the smallest natural number. This is not true, because natural numbers refer to positive integers, and "0" is the only non-positive and non-negative integer, so "0" does not belong to the family of natural numbers.

1" is indeed the smallest of the natural number family.

Fourth, one yuan ** went.

Three people lived in a hotel, each person per day ** is ten yuan, each person paid ten yuan, a total of thirty yuan to the boss, and then the boss discounted five yuan, let the waiter return to them, the waiter secretly hid two yuan, the remaining three yuan each returned one yuan, that is to say, each person consumed 9 yuan. The three people spent a total of 27 yuan, plus the 2 yuan hidden by the waiter, for a total of 29 yuan. So where does the dollar go?

Leave everyone with questions.

Mathematics tabloid 4th grade content can write some interesting math stories, as follows:

Fun Math Stories (1):

During the Warring States Period, King Qi Wei and the general Tian Ji raced horses, and King Qi Wei and Tian Ji each had three good horses: upper horses, middle horses and lower horses. The race is divided into three races, with each horse being wagered on a thousand gold.

Since the horsepower of the two is almost the same, and King Qi Wei's horse is better than Tian Ji's horse of the corresponding level, so most people think that Tian Ji will definitely lose.

However, Tian Ji took the opinion of the doorman Sun Bin (a famous military strategist), and used the dismount to the upper horse of King Qi Wei, the upper horse to the middle horse of King Qi Wei, and the middle horse to the dismount of King Qi Wei, and as a result, Tian Ji defeated King Qi Wei 2-1 and won a thousand gold. This is an example of China's ancient application of the idea of countermeasures to solve problems.

Fun Math Stories (2):

When Gauss was still in the second grade of elementary school, one day his math teacher wanted to use the class time to deal with some personal matters, so he planned to give the students a difficult problem to practice. His title is: 1+2+3+4+5+6+7+8+9+10=?

In the blink of an eye, Gauss had stopped writing and sat idlely. The teacher saw it and angrily reprimanded Gauss. But Gauss said he had already figured out the answer, which was 55.

Gauss replied, "I just found out that the sum of 1 and 10 is the sum of 9 and the sum of 8 and the sum of 7 and the sum of 6 is still 11, and because 11 + 11 + 11 + 11 + 11 + 11 = 55, that's how I calculated it." ”

Fun Math Stories (3):

The problem of chickens and rabbits in the same cage is one of the famous interesting questions in ancient China. About 1,500 years ago, Sun Tzu's Sutra recorded this hilarious question. The book is described as follows: Today there are chickens and rabbits in the same cage, with thirty-five heads on the top and ninety-four feet on the bottom.

The meaning of these four sentences is: there are several chickens and rabbits in the same cage, counting from above, there are 35 heads; Counting from below, there are 94 feet. How many chickens and rabbits are in the cage?

Will you answer this question? Do you want to understand how this question is answered in the Sutra of Sun Tzu?

The idea is this: if you cut off half of the feet of each chicken and each rabbit, then each chicken will become a "one-horned chicken" and each rabbit will become a "two-legged rabbit". Thus, (1) the total number of chickens and rabbits has changed from 94 to 47; (2) If there is a rabbit in the cage, the total number of feet is 1 more than the total number of heads.

Therefore, the difference between the total number of feet 47 and the total number of heads 35 is the number of rabbits, i.e., 47 35 12 (only). Obviously, the number of chickens is 35 12 23 (only).

The math hand-copied newspaper is simple and beautiful, and the drawing skills are beautiful.

1. To draw a mathematical handwritten newspaper, you should draw mathematical elements, such as numbers, triangles, rulers, etc., which can be drawn in.

2. The hand-copied newspaper of the subject class, the border can be in the style of a blackboard or the style of a book, which is a great layout.

3. If you want to draw some simple math tabloids, you can also focus on borders, and it is also great to draw a geometric border.

Digital: Dust accompanimentDigit refers to the writing of numbers, the numbers are arranged side by side in a horizontal column, and a number occupies a position, and these positions are called digits. From the right end, the first digit is "single digit", the second digit is "ten", the third digit is "hundred", the fourth digit is "thousand", the fifth digit is "ten thousand", and so on.

This shows that the concepts of counting units and digits are different.

The Creation of Numbers: The Origin of Arabic Numerals: After the ancient Indians created Arabic numerals, they spread to the Arab region around the 7th century AD.

By the 13th century, the Italian mathematician Fibonacci wrote the Book of Abacus, in which he gave a detailed introduction to Arabic numerals. Later, these numbers were transmitted from the Arab region to Europe, and the Europeans only knew that these numbers were imported from the Arab region, so they called these numbers Arabic numerals. Later, these figures spread from Europe to the rest of the world.

Arabic numerals were introduced to our country around the 13th to 14th centuries. Because there was a kind of number called "chips" in ancient China, which was more convenient to write, Arabic numerals were not popularized and used in China in time at that time. At the beginning of this century, with the absorption and introduction of foreign mathematical achievements in China, Arabic numerals began to be used slowly in China, and Arabic numerals have a history of more than 100 years in China.

Arabic numerals have now become the most commonly used numbers in people's study, life and communication.

Natural number: The number of pieces used to measure things or to express the order of things. i.e. digital 0, 1, 2, 3, 4 ,......The number represented.

The number that represents the number of objects is called a natural number, and the natural number starts from 0 (including 0), one after the other, forming an infinite collective.

Calculation tools: abacus, calculators, computers. Brother pants.

Rays: In geometry, a figure consisting of a point on a straight line and a part on its side is called a ray.
