This test is mainly divided into five parts: (1) counting and drawing as it is; (2) repeatedly; (3) comparison; (4) Draw a picture. (5) Know the location.

Judging from the content of the test paper, it is not difficult, and the students have better test scores. There are 48 students in the class, with the highest score of 100, 8 students, 90-99 students, 20 students, 80-89 students, and 3 students failed.

Second, the analysis of test paper scores and lost points

1, count and draw as it is. This part mainly examines students' counting ability and observation ability, and cultivates their corresponding thinking. Because the graphics are complex, the numbers are diverse and numerous, and the students' counting method is not scientific enough, which leads to a high score loss rate. Especially the third question, some students have more or less students.

The second question has as many connections as the first one. Investigate students' understanding of the concept of equivalence and develop their corresponding thinking. The score rate is 100%.

3. Compare with each other. There are four questions to examine students' ability to compare size, height, quantity and length. Students make many mistakes in length, and their abilities of observation, comparison and analysis need to be further improved. Some students may not understand the meaning of the question and make mistakes.

4. Draw a picture. Examining students' comparative ability, most students can draw more or less correct figures on the basis of the concept of equivalence.

5. It should be difficult to know the location in this unit, so many students lose points in this part. The eighth and second questions have a high loss rate, and a few students make mistakes in the ninth question, which may not be well combined with reality.

Third, self-reflection

In the face of grades, I don't think this is enough. It is necessary to further strengthen training, improve students' various behavior habits and study habits, strengthen the cultivation of number sense, cultivate students' interest in learning, strengthen the teaching of concepts, pay attention to developing students' listening ability, develop students' abilities of cooperation, counting and inquiry, and cultivate students' various mathematical thoughts such as space, reasoning and correspondence.

Fourthly, the teaching measures in the future.

1, strengthen their own education and teaching ability, deepen the study of textbooks, understand students, and design and explain exercises. Ask for advice from experienced teachers and learn from their valuable experience. At the same time, we use various methods to improve our classroom efficiency, grasp the breakthrough point of students' understanding and build an effective classroom.

2. Create an upward atmosphere according to the age characteristics of students, and strive to create an equal, harmonious and enterprising class atmosphere.

3. Cultivate students' habit of carefully examining questions and writing, and ask students to do and learn to check in time when doing homework or exams, so as to check whether there are any missing questions; 2. Check whether the calculation questions are wrong; 3. Check whether the exam questions are wrong.

4. Carry out special education for special students.
