If you want to find a math teacher for your child, there is no way, please advise. 20

The most important thing in mathematics is the textbook, as long as you read the textbook thoroughly, you can improve a lot of points, don't think that the concepts in the textbook are very boring, don't think that the example problems in the textbook are very simple, when taking the exam, 80% of the questions are the example problems in the textbook to be sublimated, if you do a good job of the example problems, have the ability to draw inferences, fully understand the concept, you can use the concept to reason about the problem, then half the success, the rest is to do more exercises, the size of mathematics seems to be many, in fact, it is nothing more than a few, buy a few more reputable tutorial books, In addition, mathematics must pay attention to error correction, the wrong questions in the problems that have been done must be read again, serious and do it again, error correction is very important, and there is repetition, repeated good questions, don't think that it will be, to be able to draw inferences from one another, if you do these points, it should not be a big problem, remember, you must be serious.

I know a classmate who tutors students in a second year this year.

The cram school teacher is not good, no matter in a good cram school teacher is useless, it is best to find the child's math teacher, don't care about the money, the child is important, because only their own teacher knows the child's shortcomings best, unless the teacher is not good, I think so, my child let the teacher do the results quickly.

First of all, parents should help their children analyze the root causes of poor math.

A child's learning problem is a matter that parents attach great importance to, once the child has a problem with learning, then parents will be very worried, but many parents have no way to help their children because they are not available or have a low level of education, which requires them to find a suitable tutoring class for their children. If you want to find a good tutoring class, the teacher must be very important, which requires a certain standard when choosing a math teacher, in fact, it does not mean that the more powerful the teacher, the more suitable for your child, you must find a teaching method that the child can accept, and the one that suits your child is conducive to the improvement of the child's grades. <>

When choosing a math teacher, the first thing should be to consider his sense of responsibility, a teacher who has no sense of responsibility to hand over the child to him, which is equivalent to choosing a person who looks after the child, but it does not have much effect on learning improvement. Secondly, you can look at the teacher's teaching performance, and inquire about the progress of the students he has taught, and whether they have the ability to teach the children well. Parents can also communicate with the teacher first, and judge whether he can analyze the teaching materials and the current situation of the students from a professional perspective through some communication with him, and have a general guidance direction, which is very important.

If parents have time, they can also listen to the teacher to give a lesson to see if he has any problems with his teaching ideas, and at this time they can bring their children together, after all, each teacher's teaching methods are very different, and whether their children can accept it is the most important. Because some children need strict teachers to discipline them, but some children may be attracted to the funny teaching style, it is important to learn to listen to the children in the family. Finally, take one of your child's usual test papers and hand it to the teacher for analysis to see if his comments can be to the point and in line with reality.

It is not that it is okay to throw the children in the family into the tutoring class, it is very important to choose the teacher of the tutoring class, as a parent must be attentive, after all, only the money will definitely not solve anything, the most important thing is to solve the problem of children's learning difficulties to the greatest extent, you must not ignore the feedback of your own children, and come home to ask him more about the situation.

Try to choose the kind of teacher who has been a homeroom teacher in school, this kind of teacher will generally have more teaching experience and can also give targeted guidance to children.

The math teacher must choose to be more patient and careful, and then you can see which aspects of the child's learning are not solid and not in place. Or you can choose a teacher that your child is more familiar with, such as his substitute teacher.

In fact, it is best to choose a teacher in the school, because the child's own teacher knows the child's situation better, so that he can prescribe the right medicine.

Each elevator needs to be maintained twice a month and must be serviced once every 15 days, which means you need to have each elevator serviced at least once every 15 days, for a total of twice a month. And you need to avoid Sundays for a few lines of maintenance.

There are about 22 working days in a month (excluding Sundays). Therefore, you need to perform about 14 maintenance sessions per working day (160 lifts * 2 maintenance units = 320 maintenance sessions, 320 maintenance sessions 22 working days and 14 maintenance working days).

In order to meet the requirement that one service must be done once within 15 days, you can divide the month into two 15-day cycles, with one maintenance per elevator in each cycle.

The specific plan may be as follows:

The 160 elevators were divided into two groups of 80 each.

In each 15-day cycle, each group of elevators will complete 80 maintenance sessions (one per elevator) within 11 working days, with an average of about 7 maintenance sessions per working day.

Every working day, you can perform maintenance for 7 elevators, at the same time if there are enough maintenance personnel, and if there are limited personnel, it can be scheduled according to the usage and location of each elevator.

The above is a basic plan, and the specific implementation may also need to consider other factors, such as the use of elevators, the number and capacity of maintenance personnel, necessary spare parts and tools, etc. If possible, it's best to use elevator maintenance management software to help schedule and keep track of maintenance tasks.

Based on 30 days in a month, minus 4 Sundays, there are 26 days available for maintenance work. Each of the 160 elevators needs to be overhauled 2 times, and 320 overhauls are required in a month, 320 times 26=. On average, appointments need to be completed per day. Defeat and ascension.

The 160 elevators are divided into 8 groups, each containing 20 elevators.

For the first 13 days of the month, one group of elevators is serviced every day. Avoiding Sundays ensures that each set of elevators completes their first repair during this time. In the last 13 days of the month, one group of elevators is maintained every day in the order of the same as the one in which the same group of elevators is maintained.

This ensures that each group of elevators completes the second repair within this time. According to such a plan, it should be possible to complete the requirements of the question.

Assuming that there are 30 days in a month, then one overhaul in 15 days requires 160 elevators to be divided into two groups of 80 elevators each. The maintenance time interval of each group is 15 days, that is, the first group starts the maintenance on the 1st, and the second group starts the maintenance on the 16th. Each elevator needs to be serviced twice a month, so each group needs to be serviced twice a month.

In order to avoid Sundays, the maintenance schedule can be scheduled to take place from Monday to Saturday, with 10 elevators per day, so that each group needs to overhaul 16 elevators per day, and the overhaul can be completed once in 5 days, and then a second overhaul after 10 days. This allows for each elevator to be overhauled twice a month and avoids Sundays.

First of all, we can calculate that the time interval for each overhaul of each elevator is days (15 days 2).

Then, we can divide the 160 elevators into 10 groups of 16 elevators each. The maintenance interval for each group is 75 days (day 10), that is, each group undergoes a comprehensive maintenance every 75 days.

In each month, we can schedule 10 groups of elevators for maintenance in two time periods, each for 15 days. That is to say, each group of elevators must be overhauled at least once every month, and a certain number of elevators must be overhauled every day in each time period to complete the requirements that each elevator needs to be overhauled twice a month.

Finally, we need to be careful to avoid Sundays when scheduling maintenance times, and we can move the maintenance cycle forward or backward by one day.

The maintenance plan of the elevator can be arranged according to the following scheme:

1.From Monday to Saturday, 20 elevators are maintained every day, and the plan is as follows:

Day 1: Maintenance of elevators 1-20;

Day 2: Maintenance of elevator 21-40;

Day 3: Maintenance of elevators 41-60;

Day 4: Maintenance of elevators 61-80;

Day 5: Maintenance of No. 81-100 State Calendar Elevator;

Day 6: Maintenance of elevator 101-120;

Day 7: Rest.

2.Every month, each elevator needs to be maintained twice, so 160 elevators can be divided into two batches

The 1st-80th elevator: 1 maintenance in the first 15 days (Monday to Saturday), 1 maintenance in the second 15 days (Monday to Saturday);

The 81st-160th elevator: 1 time in the 2nd 15 days (Monday to Saturday), 1 time in the 3rd 15 days (Monday to Saturday).

Please note that the above arrangements ensure that each elevator is scheduled on a daily basis and that Sundays do not interfere with the schedule.

In order to meet the requirements, we can develop a maintenance plan for the elevator under the seepage of the hailstone:

The 160 elevators were divided into teams, each containing a similar number of elevators.

Every working day (Monday to Saturday), maintenance work is carried out.

The number of elevators to be overhauled per day should be feasible and not exceed the working capacity and time limit of maintenance personnel.

Here's an example of a possible plan:

The 160 elevators were divided into 8 groups of 20 elevators.

Two teams are selected for maintenance every day, and the elevators in each team take turns for maintenance.

The disadvantages of the weekday are as follows:

Monday: Team 1 and Team 2 overhaul.

Tuesday: Group 3 and Team 4 overhaul.

Wednesday: Group 5 and Team 6 overhaul.

Thursday: Group 7 and Group 8 overhaul.

Friday: Group 1 and Group 3 overhaul.

Saturday: Team 2 and Team 4 overhaul.

With this program, each elevator will be serviced once within 15 days and twice in a month. At the same time, Sundays were avoided for maintenance.

Please note that the specific maintenance plan can be adjusted according to the actual situation and the work schedule of the maintenance personnel. This is just a sample plan, and you can be flexible with your actual needs.

Divide the elevators into 5 groups of 32 elevators each.

Arrange a group of maintenance work every day, which lasts for 5 working days and rotates once.

Each elevator must be overhauled once per maintenance cycle, so each group needs to overhaul each Zison elevator twice a month.

In order to meet the requirement that one overhaul must be carried out within 15 days, the 32 elevators in each group can be divided into two batches of 16 elevators each. On the 8th day, the first batch of 16 elevators was overhauled; On the 23rd day of preparation, the second batch of 16 elevators was overhauled. In this way, all elevators will be overhauled once within 15 days.

In order to ensure the efficiency and quality of maintenance, it is recommended that the 24 elevators of the group should be maintained daily in the first three days of the maintenance cycle of each group, and the remaining 8 elevators should be repaired and inspected in the last two days.

Avoid Sundays, and the elevator can be serviced on weekdays other than Saturdays and Sundays.

Through the above scheme, it can meet the requirements that each elevator must be overhauled twice a month, must be overhauled once within 15 days, and avoid Sundays, and can better arrange the daily maintenance and major repairs of the elevator during the maintenance cycle. If you have any questions, please feel free to ask.

For reference only, the specific situation can be modified separately.

Is it junior high school math or high school, can you tell me first?

According to the requirements, 160 elevators need to complete at least one overhaul within 15 days, and each elevator needs to be overhauled twice within each Yuanzhi month, so as to avoid maintenance arrangements on Sundays. The following plans can be made:

1.Maintenance team arrangement.

The 160 elevators were divided into 4 groups of 40 elevators. The maintenance team is composed of at least two maintenance personnel, and each team is coordinated and managed by a person in charge.

2.Schedule service schedules.

Each month is calculated on a 30-day basis, and a total of 3 overhauls need to be completed. In order to avoid Sundays, each overhaul should be from Monday to Saturday, and each overhaul should be scheduled within 3 days, e.g. from Monday to Wednesday.

3.Arrange the service sequence.

Since each elevator needs to be serviced twice a month, 160 elevators need to be sequenced. In the first month, all elevators are arranged in ascending order by number, with elevators 1 to 40 in the first batch, elevators 41 to 80 in the second batch, and so on, with elevators 121 to 160 in the fourth batch. According to the plan, 3 overhauls are carried out every month, and each overhaul includes 2 batches of elevators, each batch of 40 elevators.

Each elevator needs to be overhauled twice in a month, and the first overhaul and the second overhaul of each elevator should be spaced as far apart as possible, and it is best not to concentrate on completing it in a short time.

4.Maintenance arrangement.

For example, from the first day of the first month, overhauls are carried out in ascending order. Elevators No. 1 to No. 40 are overhauled in the first week of the first month, i.e., the first day, and in the fourth week, i.e., on the first day; Elevators No. 41 to No. 80 are overhauled in the second week of the first month, that is, on the first day, and in the third week, that is, on the first day, the inspection team is repaired; Elevators No. 81 to 120 are overhauled in the 3rd week of the 1st month, i.e., the first day, and in the 2nd week, i.e., on the first day; Elevators 121 to 160 are serviced in the 4th week of the 1st month, i.e., the first day, and in the 2nd week, i.e., on the first day.

5.Monthly plan.

Create a new monthly plan based on the number of days and weeks in each month, and then adjust and optimize it according to the monthly maintenance situation to ensure that the maintenance work is completed on time. The monthly plan should detail the maintenance time and maintenance content of each elevator for management and supervision.

The above is a detailed schedule of possible times and steps. In actual maintenance work, the specific time and steps may need to be adjusted according to the actual situation and needs. It is recommended that attention should be paid to the safety of the equipment in actual operation to ensure the safety of maintenance personnel.
