Depressed, is my son s fourth grade math problem difficult?

Assuming that t minutes have been walked, there are 90t-60t=180x2, then t=12, s=60t+180=900m. Draw a picture to understand!

900 meters Let's say my sister walked x meters, and the time it took to meet was t minutes.

x=60tx+180+180=90t

The solution is t=12 and x=720

720 + 180 = 900 meters.

Suppose x minutes to meet, 90x-180=60x+180, and solve x=12

90x-180 = 90x12-180 = 900 meters.

A: Their home is 900 meters from the school.

900 meters, my brother arrived at the school gate and found that he didn't bring the books, so he returned to meet his sister at 180 meters away from school, 180 meters my brother needs to walk for 2 minutes, then my sister walked 120 meters in 2 minutes, then my brother is 300 meters away from my sister when I arrive at school, my brother is 30 meters faster than my sister every minute, and it takes 10 minutes to distance 300 meters, so the school is 900 meters away from home.

Solution: There are x meters.

x/90+180/90=（x-180）/60

x=900A: 900 meters from home to school.

There are x meters of walking and the road takes the same time.

Brother time: (x+180) 90

Sister Time: (X-180) 60

x+180）/90=（x-180）/60

x=900

At the last moment of encounter, the elder brother walked 360 meters more than the younger sister, and the elder brother walked 30 meters faster than the younger sister per minute, so the elder brother walked for a total of 12 minutes, and if he removed the one who turned back, it took the elder brother 10 minutes to get to school, that is, 900 meters away from home to school.

Simple. Set the time to x

There are 90x-60x=180*2

x=12Distance=12*90-180=900m

The first grade of primary school mathematics is not too difficult as a whole, mainly whether the learning of usual knowledge is well supervised, and the reason for the poor performance of the first grade of primary school mathematics:

Insufficient knowledge.

Parents of elementary school students can imagine that before elementary school students enter elementary school, the mathematics they learn in kindergarten is very simple. Even some students have hardly listened to lectures or completed regular homework during kindergarten, and these primary school students naturally do not have enough basic knowledge reserves. Without any foundation in mathematics, it becomes very difficult for elementary school students to learn mathematics.

During the period when children are promoted from kindergarten to primary school, they do not systematically review the mathematics knowledge in kindergarten. As a result, these students' prior knowledge is insufficient, and some of the knowledge they have learned has been forgotten, resulting in these primary school students feeling that mathematics is very difficult to learn.

Insufficient parental supervision.

In elementary school, there is a transition time before moving on to first grade, and if primary school students can make full use of this summer vacation and learn some first-grade knowledge, perhaps these children will not find it difficult to learn first-grade mathematics. Parents do not have a sense of crisis, resulting in these primary school students not being exposed to any first-grade mathematics knowledge before the start of school, resulting in students not being able to learn mathematics well.

Parents should supervise the learning of these students during their children's kindergarten years, and it is not that they do not learn any subject knowledge during kindergarten. Parents should communicate with the kindergarten teachers in a timely manner to understand what homework is assigned by the school every day, supervise students to complete the homework in a timely manner, and lay a solid foundation during the kindergarten period.

Teacher management is not strict.

Some elementary school students feel that math is very difficult after entering the first grade of primary school, what is the reason? Part of it is also the responsibility of kindergarten teachers, kindergarten teachers are not strict in supervising learning, and most of the kindergarten teachers' energy is mainly to solve the problems of children's lives. As a result, these children do not have strict management, do not understand the subject knowledge of mathematics and Chinese, and do not lay a good foundation.

Grade 1 is the most basic stage of learning, and the same is true for mathematics, which is also the most basic, including: numbers and their addition, subtraction, multiplication and division.

1. Understand the rules of the digital world, such as how single digits, two digits and multiple digits change, and what are the calculation principles of addition, subtraction, multiplication and division;

2. If you want to learn the same thing, you must work hard, you need to do more exercises, practice makes perfect, do more problems, and deepen the rules between numbers, you will be more handy, which will be of good help to your higher level of mathematics in the future;

3. Don't give up, don't give up learning because of a bad math score for a while, be firm in your confidence, and know that if you spend time, you will definitely be able to learn well and do better than others. Unfold.

Grade 4 math is not difficult, as long as you consolidate your foundation and do more exercises, math is very simple, and you don't have to worry about whether you can learn it.

Mathematics in the fourth grade is actually relatively simple, not difficult at all, if you think that the current primary school mathematics is difficult, then after you go to middle school or university, that mathematics will be astronomical for you.

1.Mathematics in the fourth grade is generally relatively easy, but the level of difficulty is also very different for children of different levels.

Grade 4 math is not very difficult, and grade 4 math only requires learning about decimals, fractions, graphs, and positions.

Mathematics in the fourth grade is certainly very difficult for some children, but it is very simple for some adults, so it is necessary to work hard to cultivate children's enthusiasm for learning and mathematics, and only in this way can children really learn mathematics well.

This stage of mathematics is the more critical stage in the mathematics stage, and the knowledge of mathematics is also the basic knowledge. Accurate learning strategies are particularly crucial for students in the fourth grade, which not only affirms the ability to hone students' thinking skills, but also saves students' study time. Xueda Education will make the students develop their own learning strategies, integrate the knowledge they have learned, and assist the students to set up a unique information system, so that the students can figure out the relationship between the knowledge, so that the students do not have questions for the fourth grade mathematics.

Highlights of the 4th grade math tutorial class: The 4th grade math tutoring class can have a lot of experienced tutors, who have their own unique views on the tutoring of the students, and must find the difficulties of the students and explain them immediately.

Hello, the current fourth-grade math problems are still a bit level, but as long as you are careful, it is not difficult.

Analyze the test paper first, see what the problem is mainly (such as whether he really can't or is not confident), if he is careful, he should cultivate his habit and pay more attention when completing homework. If not, it is recommended to buy some interesting mathematics and other books at home to cultivate interest, after all, the most important thing in the fourth grade is interest, there is no need to apply for cram school to be stressful, usually parents can do it with him and guide it. If it's just that you didn't do well in the exam this time, then accompany him to analyze the wrong questions and give him more encouragement:

If you don't do well in one test, you just need to be properly encouraged and seriously corrected. If you don't do well in the exam for a long time, you should find more reasons, you can go to cram school, but it is best to ask the child's consent, if he is reluctant, you can take measures to let him do more extracurricular questions, do a little bit every week or every day, if he doesn't want to, you can exchange conditions with him, such as how much he does in a week to make him fulfill a wish or something, or how much he can do in the exam, it's up to you. However, fourth-year students don't have to worry too much if they don't do well in the exam, because it will change in the future, so it's best not to take any tough measures, of course, it's important to have a solid foundation.

I don't know if it's Olympiad math or school math.

If it is a school textbook, mathematics in the fourth grade should not be difficult, and there is no need to find a cram school.

If the child does not do well in the exam, we should not blame the child in a hurry, and if the child is depressed, appropriate comfort is also okay.

We should help our children analyze why they didn't do well in the exam.

Did you fail the exam once? Or haven't you done well in a long time?

Was it a sloppy mistake? Or will a lot of questions not?

Only by analyzing the specific situation and finding a solution can we really solve the problem, and blind blame and looking for cram schools are not advisable.

One class completed 1/3 of the total

The second shift completed 1/4 of the total

Class 3 completed 1/5 of the total

Class 4 completed:

276 pcs.

1.Causes: (1) slow thinking speed, (2) slow thinking habits, (3) unfamiliar question types.

2.Correction methods: (1) improve thinking speed, (2) improve thinking habits, (3) strengthen question type practice.

If you can do it, do it again (change your thinking habits), and complete it within a limited time!

Hello landlord.

Since the promulgation of the Mathematics Curriculum Standards for Full-time Compulsory Education (Experimental Draft), Beijing Normal University Press, People's Education Press, and Jiangsu Education Press have respectively published a set of experimental textbooks for primary school mathematics that reflect the new curriculum concept (referred to as Beijing Normal University Edition, Renjiao Edition, and Jiangsu Education Edition).

The mathematics of the people's education version, the fourth grade mainly learns decimals, fractions, graphs and positions, etc., connecting the knowledge of the third grade and the fifth grade, and the overall difficulty is not great (occasionally there are more difficult thinking questions and the like).

In fact, compared with book knowledge, learning attitude is more important, it is not difficult for those who know, and those who are difficult will not, only those who work hard and diligently can turn difficulties into easy.

I won't say big words, I hope it helps you.

Hello, there is nothing difficult in the world, only afraid of people with hearts, as long as you work hard, there is no bad learning.

Fourth-grade math should be said to be very simple, as long as you listen carefully to the class, it is basically no problem.

It's not hard. That's right, just got to the score or something.

It's not difficult to get on the heart, it's difficult to get on the heart, it all depends on the attitude, and the knowledge points are like that.

Much deeper than the third grade. There are more practical problems.

Some are brain teasers and not easy.

It is not difficult to study seriously, but it is difficult to study seriously.

Hee-hee......Rest assured.

Can you not say so much useless?

Isn't it just addition, subtraction, multiplication, and division?

If the three-digit number misses a zero, then the two-digit number is one-tenth of the original three-digit number, in other words, ten times the two-digit number is equal to the three-digit number. For example: 110 and 11, 2520 and 252, 3580 and 358

Suppose: Two digits are x

Then there is: 10x-x=684

x=7610x=760

The original number was 760

In order to improve the accuracy of calculations and reduce children's calculation errors, it is necessary to take practical methods to correct them according to the actual situation.

1) Strengthen oral arithmetic training, so that children practice makes perfect.

Oral arithmetic is the basis of pen arithmetic, the minimum basic skills that children should have, and a good means to train mental agility. Only by improving the ability of oral arithmetic can we improve the speed of written arithmetic and the accuracy of arithmetic; Only by strengthening the training of oral arithmetic can we lay a solid foundation for arithmetic. Insist on spending 3-5 minutes a day on oral arithmetic training and memorize some common data.

2) Through comparative training, children can develop serious habits.

Psychological research has shown that doing the same work mechanically and repeatedly will make people bored, therefore, it is not possible to improve the accuracy of children's calculations by strengthening the problems alone, because children often do not want to calculate the second time after calculating once, and should be based on the psychological characteristics of children, follow the rules of teaching, and use different measures to consolidate. Through comparative training, overcome the negative effect of children's mindset, make children develop the habit of reading problems carefully, calculating carefully, and cultivating children's ability to compare and discriminate.

3) Develop the habit of careful calculation.

In learning operations, it is necessary to train children to have a calm and calm attitude towards learning. When encountering a calculation problem with large numbers and many steps, it is necessary to be not impatient, think calmly, and calculate patiently. When calculating, it is required to do "one look, two thoughts, three calculations, and four checks", and one look is to see each number and each operation symbol completely before doing the problem, and carry out preliminary perception; The second thought is to understand the relationship between the characteristics of the data and the operation on the basis of seeing the problem clearly, and choose a reasonable method according to the specific situation to determine the operation steps; The third calculation is to carefully calculate after determining the calculation steps and methods; The four checks are to count every step in a timely manner; Look back.

Check whether the method is reasonable and whether the data calculation result is incorrect.
