Analysis of the title of the second grade mathematics test paper
First, the examination paper situation
1, the content is comprehensive, covering a wide range, and the scores of each part are reasonable.
Curriculum standards point out that everyone gets the necessary mathematical knowledge, and different people get different development. This volume focuses on the mastery of students' basic knowledge and the cultivation of their basic abilities, and also properly examines students' learning process. The content of the test questions is comprehensive and there are four major questions. The overall examination questions well reflect the hierarchy. The examination paper is presented in an intuitive, vivid and interesting way. While examining students' basic knowledge and ability, properly examine the learning process.
2. The design of math test questions is interesting and close to life. The types of questions are embodied in: oral calculation, vertical calculation, filling in the blanks, thinking, drawing, filling in the blanks and solving practical problems. Starting from the realistic situation and knowledge and experience that students are familiar with, the test paper selects specific things that happen around students, truly understands the relationship between mathematics and life, feels the application value of mathematics, and encourages students to solve problems with their own wisdom.
Second, the students' answers
1. Calculation: The verbal calculation is very good, some students are all right, some students have one or two mistakes, and so is the written calculation. The main reason is that they read the wrong symbols or copied the wrong numbers. Most students can calculate in the right way.
2. Fill in the blanks:
Questions 2, 5, 6 and 8 have high errors, and some students lose points because of their unclear positioning in real life. Question 5: Because students have a narrow knowledge and don't know the relationship between the earth and the sun, the loss rate is high. Question 6: Because students don't understand the meaning of the question correctly, they confuse objects with pictures, so the failure rate of students is very high. Question 8 is mainly filled by some students who have missed or found irregularities.
Step 3 think, draw and fill in the blanks
For the observed object, the teacher talked much and the students practiced much, so only a few students lost points. Cut a triangle from a rectangular piece of paper. The main mistake is that the method is repeated with the illustration, and the students themselves don't pay attention to it.
Step 4 solve the problem
Most of the questions in this part are done well by students, which is the fourth question. Students don't quite understand the meaning of the question, and some students can't express it even if they know it in their hearts, so they don't finish it well.
Third, suggestions for future teaching work:
1, strengthen students' good habit of carefully examining questions and cultivate their active learning ability. Only on the basis of correctly understanding the meaning of the question can we complete the question well and cultivate students' careful habits.
2. Strengthen the connection between mathematical knowledge and real life, and attach importance to the process of knowledge formation and ability development.
3. In the future teaching, we will continue to strengthen the consolidation of basic knowledge, pay more attention to students' mastery of basic knowledge, expand appropriately on the basis of mastering basic content, and let students adapt to various types of questions.
4. In the future teaching, we should deeply reflect on students' learning style and flexibility of thinking from the mistakes in answering questions, so as to do everything and teach students in accordance with their aptitude, and lay a solid foundation for students' future study.
5. In the future, we should strengthen the research of teaching methods, comprehend, learn and understand mathematics knowledge in familiar and interesting problem situations, solve problems from different angles, expand students' thinking, stimulate students' interest in learning mathematics, pay attention to cultivating students' good study habits, and make students like and love mathematics.
Review the materials at the end of the second grade
1, the meaning of division with remainder: when some objects are divided equally, sometimes there is a surplus, and such division is division with remainder.
2. Relationship between remainder and divisor: In division with remainder, remainder must be less than divisor.
3. Vertical calculation method of split column:
(1) Write first? Factory? Represents a division symbol.
(2) Write the dividend in the divisor.
(3) Write the divisor on the left outside the divisor.
(4) Write the quotient in addition to the divisor, above the dividend, and align with the dividend.
(5) Write the product of the divisor and the quotient under the dividend (note: the same digits should be aligned).
(6) The result obtained by subtracting the product of quotient and divisor from dividend is written under the horizontal line and aligned with the unit bit.
4. try the business method of remainder division: first think about how many divisors there are in the dividend, and then try the quotient with the multiplication formula.
5, the relationship between the parts in the division formula:
Dividend? Divider = quotient+remainder
Bonus = business? Divider+remainder
Dividend = divisor? Quotient+remainder
