20 13 how many points did Shenyang xuesi cup win in mathematics?
With the announcement of the results of Xuesi Cup, students have mixed feelings. From preparing for the exam, from 8:30 am to 10:50 am, the little guys named Dou passed the Long March exam for 2 hours and 20 minutes. You are the best! Please give yourself applause!

This year's study and thinking about the cup is not difficult, but the questions are novel and there are many traps. Many children, Xiaojie, brought you an analysis post about learning and thinking about cups, hoping to help you find your own advantages and disadvantages and gain something!

Firstly, the thesis is summarized.

This Xuesi Cup exam *** 15, full score 120, and the answer time is 60 minutes.

1. Proposition direction: comprehensively investigate knowledge points such as calculation, application problems, interesting mathematics, graphics, algebra, and mathematical thinking methods. Close to life, suitable for second-grade children's reading problem-solving ability

2. Investigation scope of knowledge points: the contents of the first level (summer of senior one) to the fourth level (spring of senior two) of the twelve-level system.

3. Overall situation:

Fourth, summary.

1. Knowledge points of the test paper are comprehensive: this test paper is moderately difficult, but it involves a wide range of knowledge, requiring candidates to have a comprehensive and consolidated knowledge point reserve, resulting in a low overall score for candidates. Parents can use this test paper to help candidates analyze the loopholes in knowledge points and make plans and preparations for later study.

2. Candidates lose points mainly in the following aspects:

(1) The exam questions are unclear.

The difficulty coefficient of learning and thinking about the cup is not as big as in previous years, but there are many traps, and careless children have suffered a big loss this year.

The second problem is a very basic problem of finding quotient and remainder. Many children directly regard "30 students" as the number of boys, and come to the conclusion that two children are more than four times.

Question 8. The keywords "yes" and "no" of the queuing problem were not clearly seen, and they were mixed up when drawing. Children, we need to practice more!

Question 9: Many children have found out what two three-digit numbers are. Just add one more step and you'll get 8 points. But many answer sheets directly write two three-digit numbers without scoring.

Question 13, many children sometimes tell me that I misread "clockwise" and "counterclockwise"! To do this kind of topic, you should learn to circle important words. When reading the topic, you should first circle "Shun" and "Inverse" to remind yourself!

(2) Variant questions need to be strengthened.

Question 7: 12 and 14 belong to the knowledge points that children know, but it is not easy to start with the concept only because the variant is difficult.

To solve variant problems, we need to dig deep into the essence of knowledge points under the condition of long-term review and consolidation of existing knowledge points-that is, the more difficult we learn, the more refined we learn. I hope students don't despise the basic questions, insist on practicing and deepening their study repeatedly, and strive for a big leap.

(3) Carelessness is becoming more and more obvious.

Carelessness is a common problem of children. After every exam or competition, the word "carelessness" is what parents say the most. As early as the first grade, children's carelessness began to prevail, and in the second grade, the problem of carelessness became more and more serious.

Give some advice, hoping to help children:

Develop the habit of focusing on reading questions, especially application questions. Some important words on the topic can be marked with circles, solid lines and wavy lines. Or use simple words and pictures to record the illness.

2 overcome the problems you missed. Many children always make mistakes in the same place, so we concentrate half our energy on overcoming our own mistakes. After this conquest, let's fall in different places! Success is to do simple things repeatedly, not to mention the cultivation of study habits is a gradual process.

At the same time, we need to consider the error-prone points: is it because of carelessness or because of poor knowledge?

The above is my personal opinion, and I hope it will be helpful for my children's future study! Come on, kids!

I hope it works.
