1, pay attention to basic knowledge and reflect the characteristics of the subject.
This test focuses on students' basic knowledge, including the understanding of numbers within 20, addition and subtraction, and the combination of numbers. This knowledge is the basis of mathematics learning, and it is also the basis of cultivating students' mathematical thinking and problem-solving ability. The test questions examine students' mastery of basic knowledge through filling in the blanks, choosing and judging.
2, contact with real life, pay attention to the application ability.
This test is closely related to students' real life, and sets up a number of life-related topics, such as how much money is left after buying fruit with 20 yuan money; Count how many apples there are, and so on. These topics not only examine students' mathematical knowledge, but also examine students' living ability and problem-solving ability.
3, illustrated, stimulate interest.
The presentation of this test is rich and colorful, including both text description and picture display. These pictures are vivid and colorful, which can attract students' attention and stimulate their interest in learning.
4. Calculation questions.
The calculation questions in this exam include oral calculation, written calculation and column vertical calculation of addition and subtraction within 20. Most students can calculate correctly, but some students have problems with calculation errors or incorrect methods. Therefore, in the future teaching, we should pay attention to cultivating students' computing ability and mathematical thinking, and strengthen practice and guidance.
5. Application questions.
Application problem is the focus and difficulty of this exam, which mainly examines students' mathematical application ability and problem-solving ability. Some students can understand and answer questions well, but some students have problems such as unclear examination, unclear thinking and inaccurate expression. Therefore, in the future teaching, we should strengthen the training and guidance of applied problems and pay attention to cultivating students' ability to examine and analyze problems.
Teaching suggestion
1, create a good teaching environment: teachers should pay attention to the creation of classroom atmosphere, so that students can feel the fun of learning and actively participate in teaching activities. Students' interest in learning can be improved through games, riddles and songs.
2. Contact with real life: In mathematics teaching, we should try our best to contact with students' real life and let students understand the concepts and principles of mathematics through concrete and vivid ways. For example, when teaching addition and subtraction, students can count candy and sticks to understand.
3. Cultivate good study habits: From the beginning, we should pay attention to cultivating students' study habits, such as correct writing posture and good listening habits. Let students understand that learning mathematics is not only about learning to calculate, but more importantly, learning to think and solve problems.
