1, calculation problem. Calculate 9 small questions by mouth, 6 small questions by pen, and correct 3 small questions. The main reasons for the error are:

(1) Calculation error caused by careless copying of figures.

(2) Forget to write the number and lose points.

2. Fill-in-the-blank question: This question covers a wide range, and the score accounts for the whole volume 1/5. This topic mainly examines students' mastery of using book knowledge to solve problems in daily life. Many students can't handle problems flexibly according to the knowledge in books. More wrong questions are 3, 5, 7 and 8 small questions.

3. Multiple choice questions: * * *12. Among them, questions 4 and 5 examine the students' comprehensive application ability of what they have learned and lose points. There are still some students who don't understand the conceptual knowledge and need the teacher's explanation.

4. Graphic part. (16) The errors are mainly concentrated in the third item. We have to calculate the perimeter according to the length and width, then calculate the side length of the square, and finally draw the square. The problem is novel and students can't start.

Step 5 solve the problem. ***6 questions, of which the error rate of the second question is over 60%. The mistake in question 4 is mainly due to the calculation error.

6. Additional questions. Only a few students succeeded.

cause analysis

1, students' mastery of knowledge is limited, lacking in expansibility and unable to learn and use flexibly. The limitation of thinking leads to students' misjudgment.

2. Pay attention to the extension from class to class, but ignore common sense.

3.* * * is common among students-they don't examine the questions carefully and love to do it by feeling. Carelessness and unclear examination questions are common problems among students. It often lets students pass by perfection. The phenomenon of careless calculation is also "everywhere"!

4. Good study habits need to be strengthened.

5. Students' ability to analyze application problems is poor, and it is difficult to start with slightly complicated application problems.
