Reflection on the teaching of children's playground

Part 1: Reflection on the teaching of children's paradise

The teaching content of these two classes is the preliminary understanding of the first unit multiplication of the second grade of the second grade mathematics of Beijing Normal University. There are two points of knowledge: one is to initially understand the number of the same addend and the same addend, thus introducing multiplication, which is a main line. The second is the writing and reading of the multiplication formula, which is the basis for understanding the meaning of multiplication and the actual calculation. The difficulty in teaching is to identify the same addend and understand the different meanings represented by the two numbers before and after the multiplication. Through the above understanding and analysis of the textbooks, I am sure to use open classroom teaching.
The initial understanding of multiplication is based on the fact that students have already learned addition and subtraction. This section is the beginning of students' multiplication. Because students do not have the concept of multiplication, and this concept is difficult to establish, in this case, I start from life experience. Step by step to gradually complete the experiential teaching process of multiplication meaning, from the students' favorite riddles as the entry point, grasping the characteristics of students' psychological age and psychological needs, so the children have generated great enthusiasm from the beginning of the class. Interests have laid a good foundation for the smooth progress of classroom teaching.
Of course, there are also several shortcomings: the students' observations are not careful enough, and the expressions are somewhat lacking; some students cannot list the correct multiplication formulas, which affects the teaching effect.

Chapter 2: Reflections on the Teaching of Children's Paradise

This lesson is about the meaning of multiplication and the basic lesson of learning multiplication. This time, I boldly changed the creation of the scene and the addition of exercises to make the class more interesting and make the meaning of multiplication easier to understand.
Contact life and lead to multiplication. In the classroom, the teacher asked each child to take 4 pencils as the entrance and asked the children: "How many pencils did the 3 children bring? 5 children? 31 children in the class?" Let the children feel it again. The inconvenience of adding calculations, let the children think about how 4+4+4=12 can be represented by multiplication. The pre-schooled child can immediately say the multiplication formula, and then the teacher asks: "How did 4 come? How did 3 come?" Let students understand how the relationship between addition and multiplication changes.
With such introduction, the situational map in the textbook becomes an exercise, and the same way for students to find mathematical information, ask questions, solve problems, and solve problems quickly, and achieve the purpose of practice consolidation. After that, I showed an exercise like changing the addition formula to the multiplication formula. 2+2+2=;2+2+2+2+2+2+2=;2+2+2+2+2+2+2+2+2+2+2+2+2=;2 +2+2+2+2+2+2+2+2+2+2+2+2+2+2+2+2+2+2+2+2+2=;...... Seen below The students exclaimed 2 too much, and after the students rewrote these formulas into multiplication formulas, the calculations became neat. This kind of exercise not only allows the students to master the method of adding the multiplication method, but also feels the inconvenience of addition and the simplicity of multiplication. Through such analogy exercises, students are more aware of the meaning of multiplication is the simple operation of several equal sums.
In teaching, proper practice can really achieve the role of consolidating knowledge.

Chapter 3: Reflections on the Teaching of Children's Paradise

My advantages in teaching this lesson are:
1. It can well grasp the new curriculum concept, follow the students' age characteristics and cognitive rules, and proceed from the student's life reality, carefully designing novel, meaningful and challenging problem situations, so that students feel that mathematics is around.
2. During the teaching process, students created a relaxed and democratic classroom atmosphere. Through specific life situations, they cultivated students' ability to observe and solve problems, and stimulated students' awareness of participation, cooperation and communication, and the application of mathematics.
3. Make full use of audio-visual media to stimulate students' senses and improve the effectiveness of classroom teaching.
4. Encourage students' innovative thinking, adjust the classroom atmosphere through various types and different levels of practice, stimulate the interest of learning, and finally design open exercises to live the mathematics knowledge and achieve the predetermined teaching goals.
The shortcomings of this lesson are:
Students have a good grasp of the exercises, and the correct rate is 95%. But in the extended exercise, “1+2+3=6,3+3+3+6=15 can be directly rewritten into a multiplication formula?” Half of the students will not write, mainly because the students are solving the problem. In the process of thinking, the thinking is not flexible, not comprehensive, in the future teaching process should pay attention to the cultivation of students' thinking ability.

Part 4: Reflections on the teaching of children's paradise

First, the teaching objectives of this lesson are:
1. In the process of solving the problem, experience the process of abstracting the simultaneous addition of the same addendum into a multiplication formula, and initially understand the meaning of multiplication and appreciate the close relationship between multiplication and life.
2. The equations of the same addends are rewritten into multiplication formulas, and the names and readings of the various parts of the multiplication are mastered.
Second, in designing the teaching process of this lesson, I designed around the teaching objectives, mainly divided into:
1. Introduce the situation and discover mathematical phenomena;
2. Propose a mathematical problem and introduce multiplication;
3. The teaching addition formula is rewritten as a multiplication formula;
4. Experience the connection between multiplication and life;
5. Students practice feedback in five parts.
Third, the advantages of this lesson are: the teaching process is generally smooth, the teaching objectives are completed within the specified time, and the students' practice feedback is good.
Fourth, the shortcomings of this lesson are:
1. After rewriting the multiplication formula for 2+2+2+2=8, the time spent explaining the meanings of the numbers in the multiplication formula is too much, and the focus is not on the multiplication formula. The connection between numbers and problems.
2. Encourage less language, so that in the second half of the lesson, students' enthusiasm for learning declines.
3. The teaching process is single and there should be some changes.
Fifth, the improved method:
1. Maintain the enthusiasm of students in class through inspiring language or methods. For example: more than one group is the most active hand-lifting speech, you can get a little red flower after class.
2. When using multiplication formulas, use children's language to make students understand.
3. Can you use the “How many people are rowing?” and “How many people rest in a chair?” These two questions are used as feedback exercises for students, allowing students to choose their favorite topics and asking students to explain to students. Listen, so that students are easier to understand.

Chapter 5: Reflections on the Teaching of Children's Paradise

The children's paradise presents the plot of children playing in the children's playground. The situation map is divided into four parts: the upper left part presents a lot of situations in which children play on a trampoline, including mathematical information such as "I am 23, I am 66". The lower left part presents the situation of sitting on a dragon boat and a flying wheel, including mathematical information such as "17 people sitting on a dragon boat, 24 people on a plane, and 50 people from us." The upper right part presents the situation of playing a bumper car, including information such as 10 yuan for each ticket, 5 points for soda, and 2 yuan for mineral water. The lower right part provides the situation of sitting on a small train, including mathematical information such as time division, graphics, and length units.
During the teaching, I will guide the students to observe the picture as a whole, and guide the students to observe in a certain order on the basis of clear basic meaning, so that students can fully discover the hidden information in the figure and understand the things observed in a certain order. The method, and prepare for the following knowledge of the knowledge section. After that, I will guide the students to discover and ask math questions.
