How to teach after class exercises, how to do after class exercises that question .

1. Practice with a strong purpose.

The purpose of the practice should be strong, the first is that each practice class should have a clear purpose and highlight the key points of the practice. For example, after students have just learned how many multiplication problems, they should schedule four to five practice lessons. Clause.

In the first and second lessons, we should focus on analyzing the relationship between quantities, "find how many are and how much", find the multiplier, that is, correctly list the multiplication equations. In the third lesson, students will further understand the quantitative relationship between multiplication problems and addition, and be able to correctly judge what method to use to solve them. Clause.

In the fourth and fifth lessons, students should learn to make up their own multiplication problems, understand the relationship between two conditions and a problem, and deepen their understanding of the multiplication problems of "finding how many few". The second is that each exercise in each lesson should have a clear purpose. For example:

After students have learned the three kinds of problems related to the total relationship, in order to make the students choose the algorithm correctly, they should carry out the comparative exercises of "finding how few", "dividing by equals" and "including division" problems, and three exercises can be arranged:

1) The teacher gives three quantities, and the students make up three application problems.

For example, 6 people make 30 sets of clothes, and each person makes an average of 5 sets.

Use two of these conditions to make up a multiplication problem.

Use two of these conditions to make up an aliquot division problem.

Use two of these conditions to compile a solution that contains the application problem.

The purpose of this exercise is to help students know that there must be two divisions in a multiplication, and that a multiplication problem can be adapted into a two-division problem.

2) Practice supplementary questions for practical problems.

3) Practice to supplement the conditions for the application problem.

Through these two exercises, students will further consolidate the structure of simple multiplication and division problems, master which two quantities must be known and what quantities must be found for each problem, and deepen their understanding of the problems.

2. Exercises should be targeted.

The design of the exercises should be tailored to the actual situation of the students. Concepts that students tend to confuse and make mistakes in calculations should be fully aware of in the design of exercises.

For example, after learning the addition, subtraction, multiplication, and division problems, students often choose the algorithm incorrectly due to the interference of coincidental numbers or individual words. At this time, the teacher can consciously use distracting numbers or words to make up questions for students to answer.

For example, Xiaojun wants to draw 72 pictures, and he has already drawn 8 pictures, how many more will he draw? One student immediately thought of 72 8 9 and mistakenly listed it as a division equation. After guiding students to analyze the quantitative relationship and determine the calculation by subtraction, they can also ask:

How to change this problem, and use division to solve it? ”

3. The practice should be effective.

Practice in a variety of ways, but don't go through the motions. The teacher should not let go of the defects of students' knowledge and ability in the practice class, and pay attention to the comments after discovering them in time, and be sure to consolidate and digest the content of the exercises in the classroom.

There are always many touching scenes in life, which give me real warmth in my heart.

Countless times, an eldest sister downstairs in my house always silently cleaned the surrounding cement pavement and cleaned out the garbage in the stinky ditch downstairs. She cleans her van every acre of bad days, and then clears the space of nearly 100 meters around her when she has free time. In fact, it is the responsibility of the sanitation workers to sell these burns, however, because the sanitation workers only clean the Xunpi once a day, they may not be busy.

So, she did it for her. Not only her, but also some middle-aged women from southern Fujian, I was originally strangers to them, but because we lived in the same community, I often received cordial greetings from them. The greetings of these strangers and their amiable smiling faces made my ordinary life a little more touching and created a harmonious atmosphere.

What touched me the most in the article was the flower cat, because it did not distinguish between each other and displayed maternal love and selfless dedication. We should also help students who are in difficulty in our lives.
