Math Moro 4th grade homework. Analysis of the most complex and extraordinary tasks in the Moro textbook of mathematics
Publisher: Enlightenment 2016.
Mathematics is one of the most important sciences. It is closely related to physics and chemistry, without which it is impossible to imagine scientific progress. AT modern world numbers at every step, you can't live without manipulating them. It is not for nothing that she is called the "Queen of Sciences", because all the achievements of science and technology have become possible thanks to calculations.
We can safely say that mathematics streamlines life. Schoolchildren begin to study it from the first grade, and continue to deepen their knowledge even after graduation. Homework is often a problem for a student. You can forget or skip a topic at school, and then it becomes unclear how to do the exercises from the textbook.
Recipe - what is it?
Collection of ready-made homework M.I. Moro, M.A. Bantova, G.V. Beltyukova can make life easier for the student and his parents. In him find the correct answers to all the numbers that are only in the tutorial.
Fourth grade is a difficult time for a child. For the year you need to get a lot of knowledge needed in the future, and this requires discipline and perseverance. Not everyone can boast of this. Children want to go for walks, not sit in class and listen to teachers.
Benefit or harm
There is a stereotype that having the right exercise solutions hinders education. That students simply write off without thinking with their heads. But this is a delusion, the data from the collection of ready-made tasks will help to compare the result, and also demonstrate the solution. You can clearly see how the calculations are carried out.
Imagine a situation: a student has not mastered the material in the lesson, and does not know how to approach the tasks. Help online GDZ M.I. Moreau one can understand the logic based on the solution shown.
Parents can make sure that he understood the topic, and are not afraid for academic performance. What does this kind of literature provide?
- clarification of topics
- saving time and effort
- confidence in the right decision
- self-learning opportunity
You can't just write off examples from the solution book. This will harm academic performance and will be noticeable in tests and verification papers. You need to try to decide for yourself, and if it causes difficulties, resort to the allowance. All information provided complies with the Federal State Educational Standard.

- The school curriculum in the 4th grade in mathematics has some features due to the fact that this is the graduating class in primary school. Along with the new material, there is a section with a repetition of the subject covered over the past three academic year. Tasks and examples become more complicated, you also need to learn how to perform actions with large numbers, and parents cannot always correctly explain how to solve various tasks. However, using GDZ in mathematics grade 4 M.I. Moro, they will help the student understand the solution.
- It does not matter what causes difficulties for the child: mathematical operations or new concepts - thanks to the solution book, he will be able to clarify incomprehensible nuances. Perhaps a fourth-grader finds it difficult to multiply, divide by two-digit and three-digit numbers, or find the arithmetic mean - GDZ will always help to cope with the work assigned at home. For a better understanding, you can study the solved problem in detail, and let the student solve a similar one on his own.
- All tasks are considered in detail here, so parents can easily explain how to solve a problem with complex calculations or an example with many actions. And with the help of the analysis of logical tasks, it is not difficult to consolidate the child's knowledge of units, tens, hundreds. The specified Moro Mathematics 4th grade solver will allow parents to make sure that their student correctly solves homework.
- The last class of the elementary school is the time of active and intensive preparation, summing up the results of mastering school curriculum for grades 1-4. Teachers, schoolchildren and parents note that for fourth-graders, math assignments often become a problem. This is due to the material in this discipline that became more complicated in the fourth grade of the school. For its successful assimilation, well-organized training, high-quality study guides and guides to them. You can choose the right kit both on your own and relying on the help of tutors, subject teachers, and leaders of mathematical circles.
- Many schools use the "School of Russia" program as a basic teaching and learning method. The subject line in mathematics in it is recognized as strong enough and logically understandable to fourth-graders. In order to master the entire course without problems, classes on GDZ should be carried out:
- systematically, according to a predetermined plan that takes into account the fourth-grader's interest in mathematics, his level of preparation, abilities and goals;
- comprehensively, focusing not only on the basic textbook on the subject, but also using a set of suitable workshops, control and verification materials;
- regularly, allocating sufficient time for preparation;
- mastering the methodology of self-control and regularly evaluating the results achieved, identifying and leveling problems. - Among the effective teaching materials, experts name the complex in mathematics for the 4th grade, offered by Moro M.I. The main topics studied within the discipline in the fourth grade according to this complex were:
- multiplication, division by single-digit numbers;
- indicators of movement - distance, time and speed, their interaction, solving problems with these mathematical quantities;
- multiplication and division by numbers ending in zeros;
- multiplication and division by two-digit and three-digit numbers. - In addition to the basic textbook, fourth-graders are also recommended the following manuals and collections by this author:
- mathematical dictations;
- independent work;
- test materials;
- workbooks;
- final control and others.
You can complete the textbook with workshops by other authors, including those recommended for the Moro textbook or without such recommendations. The tasks offered in them are universal and will allow you to work out even the most complex topics in mathematics for the fourth grade with high quality.

When asked how old he was, grandfather answered like this: If I live another half of what I lived, and one more year, it will be exactly 100. How old is grandfather?
Solution
(100-1): 1.5 = 66 years. But in the 4th grade, they are not yet familiar with numbers like 1.5. Therefore, it would be more correct to find the age relative to a multiple of the smallest value. In our case, this is half of how much grandfather has already lived. That is...
1) 100-1 = 99 how much grandfather will live if he lives another half of what he lived
2) 99:3=33 half of what grandfather lived
3) 33*2=66 years old grandfather

Task in the fields about birds Each row adds 1 bird. In this case, the first row and the last will give an average number that will be the same for the second and penultimate row, for the third and penultimate, etc. Based on this, you can understand that you need to find the average number between the extreme rows and multiply it by the number of rows. If the average is not equal to a whole number, then you can artificially add another row and subtract it at the end in the calculations. As a result, according to this logic, the following is obtained: For 9 rows (9+1): 2*9=45 birds For 15 rows (15+1): 2*15=120 birds For 20 rows (21+1): 2*21 -21=210 birds Page 5 task 8 A stork can fly at a speed of 600 m/min. How far will it travel in 1 second? Write down the flight speed of the stork in different units. Solution: If a stork flies 600 m per minute, then it will fly 60 times less per second, since there are 60 seconds in a minute. That is... 600:60=10 meters per second. If you imagine in km per hour, then you need to divide by 1000, since there are so many meters in km and multiply by 3600, since there are so many seconds in an hour. 10*3600:1000=36 km/h stork speed That is 36 km/h=600 m/min = 10 m/s.
Page 7 task 22 The motor ship covers the same distance in 4 hours as the motor boat does in 9 hours. Find out the speed of the motor boat if it is known that the speed of the motor ship is 36 km/h.

Page 11 task 4 At the same time, two trains left to meet each other: from Moscow - freight, and from St. Petersburg - passenger. The speed of the passenger train was twice that of the freight train. At what distance from Moscow will the trains meet, if we assume that the distance between these cities is 660 km? Solution: In the same time, a passenger train will travel twice as far as a freight train. That is, if we divide the entire distance, then 2/3 will pass the passenger and 1/3 will pass the freight before they meet, that is, they will overcome the entire path between the cities. As a result... 1) 660*1/3=220 km this distance will be covered by a freight train and trains will meet at this distance from Moscow.

Primary school is the main stage in the development of a child. During this period, he laid the key knowledge in the field of exact sciences, which he will use throughout his life. Mathematics is the most important subject in the education system. Therefore, in order for the student to be able to master it well, the team of authors: M.I. Moro, M.A. Bantova, G.V. Beltyukova developed an online solution book with correct answers. The collection for grade 4 is fully consistent with the textbook of the Prosveshchenie publishing house, published in 2015. This methodological complex is relevant for 2019. Many teachers and private tutors use it in their practice, creating their own unique programs and notes based on the manual.
How to improve academic performance with GDZ in mathematics by Moro, Bantova, Beltyukova?
In the lessons, the child develops the basic skills and abilities of working with numbers. He learns to add, subtract, multiply, distinguish between fractions and whole numbers. The teacher tries to fully explain all the new information, give examples to all the rules and exceptions. Of course, the child learns most of the material within the walls of the school, but independent activity is also important. It is necessary to do all homework correctly, learn all topics, work out complex exercises. Not always a child alone can cope with this. Therefore, a collection of mathematics by Moro and Bantova comes to the rescue, which can increase academic performance and reduce time costs.
Advantages of an electronic source for children:
