Teaching objectives

1. Let students go through the process of exploring the calculation method of division with remainder, master the method of trial quotient, understand that the remainder is less than the divisor, and calculate the division with remainder with single digits (quotient is single digits) by vertical method.

2. Cultivate students' abilities of preliminary observation and generalization and their attitudes and habits of actively participating in learning activities.

Vertical calculation with remainder division is the second lesson of Unit 1 in Volume 2, Grade 2, Jiangsu Education Press. In this lesson, the children have got a preliminary understanding of division with remainder. This lesson focuses on the difficulties and guides students to explore the calculation method of division with remainder, and understand that divisor is less than remainder.

This semester, in the first class of Unit 1, students have a preliminary understanding of division with remainder. But how to use vertical computing is a new challenge for children. In teaching. In order to make students master the knowledge to be learned in this lesson more firmly, it is mainly done by letting students do it themselves, trying vertical calculation independently, and talking about the meaning expressed in the vertical part of division, which can stimulate students' initiative in learning. Finally, add the necessary exercises. Through practice, students can master and use the vertical calculation method of remainder division skillfully.

Through this grinding class, our second-grade math teacher gave me valuable advice. After class, I constantly reflect on teaching and find the following problems in the teaching process: 1, creating situations, reviewing and introducing new ideas. It will be more effective to show questions to test students' mastery of knowledge. 2. In the new teaching process, for example, when children look at pictures, teachers can guide students to talk about the information in the pictures first, and then list the division formulas. Finally, the calculation steps of vertical division of teacher education. Example 2 Let the children speak for themselves. After understanding the meaning of the picture through watching, guide the students to express boldly, then list the formulas, encourage the students to say the calculation method again and perform on stage. Finally, by comparing and observing the differences between the two formulas, guide the students to tell the differences themselves. In teaching, students should be given more time to observe and think. 3. Consolidate the practice link. After mastering the vertical writing of division in the table and the vertical writing with remainder protection, consolidate the exercise in time. Design exercises should be organized. The first little question, encourage students to put a pendulum on the stage and then calculate. The second small vertical calculation, we should talk about the calculation process with students of different learning levels, and strengthen the language expression ability and narrative ability. The third small problem is to solve practical problems, let students say the meaning of the problem first, and then formulate formulas to cultivate students' active learning ability. Finally, in the summary session, ask the students to talk about what they have learned in this class. Students are not familiar with the names of each part of vertical division calculation with remainder, and they lack the process of observing and comparing vertical division calculation by themselves in the teaching process. 5. Blackboard design. Pay attention to the writing standard, the font size and spacing are moderate, and highlight it with colored chalk if necessary. The evaluation of the students in this class is not enough. In the future teaching, we should make good use of this method to evaluate students in all directions and aspects.

Through this grinding class, I will constantly reflect on the problems existing in my teaching and strive to make my classroom teaching more exciting and effective in the future.
