The math teaching plan of kindergarten big class includes reflection: understanding the cylinder

As a teacher, it is necessary to carefully prepare teaching plans. With the help of teaching plans, the teaching quality can be improved and the expected teaching effect can be achieved. How to write lesson plans to play a better role? The following are the math teaching plans for large classes in kindergarten that I collected, including reflection: Understanding the cylinder, for reference only, let's have a look.

The math teaching plan of kindergarten large class includes reflection: understanding the design idea of cylinder 1;

"Understanding cylinders" is the content of next semester's big class. I put it in the last semester for teaching, and mainly focused on the basic characteristics of the cylinder in the selection of content. The children in our class know something about circles and balls in Montessori's works. So, I naturally drew a "cylinder" by using the superposition of circles, and then compared it with a sphere, and I felt the basic characteristics of the cylinder in the game of "rolling" and "stacking". The whole teaching activity, in the arrangement of links, follows children's cognitive characteristics, from physical objects to graphics, from concrete to abstract, step by step, interlocking.

Activity objectives:

1. Know the cylinder and perceive its basic characteristics.

2. Develop the ability of observation, comparison and generalization in the game of "rolling" and "overlapping".

Activity preparation:

65438+6 0 yuan coins, 1 ball machine, multimedia courseware, children's books.

Activity flow:

(1) Stack one together to extract the cylinder.

1, show the coin and ask: What is this? What shape is it? What happens when you stack so many round coins?

2. Explain the operation requirements: coins should be stacked neatly; Double-sided tape is put in the CD.

3. communication: what will round coins become when they are stacked?

4. Summary: We call an object whose upper and lower surfaces are circles with the same size and whose upper and lower surfaces are as thick as cylinders.

(2) Distinguish between sphere and cylinder.

1, get out, tell me what's the difference between them? (Requirements: Scroll on the table)

2. Summary: The sphere can roll in different directions; Cylinders can only roll forward and backward.

The ball rolls very fast; The cylinder rolls slowly.

The sphere can roll on any surface; The cylinder can only roll sideways.

When the ball hits an obstacle, it will roll in different directions; The cylinder stopped when it hit an obstacle.

3. Fold a stack to see who is taller and why.

4. Summary: Spheres cannot be superimposed, but cylinders can be superimposed.

(3) Think about it and look for spheres and cylinders in your life.

1, show the courseware: looking for cylinders in kindergarten.

There are still many jars in life. You can also continue to look for cylinders in our lives at home, parks, supermarkets and squares.

(d) Outreach activities: look for spheres and cylinders in pictures (children's books)

Colour the cylinder green (P22 for children's mathematics in the first volume of the big class)

Activity reflection:

Children often come into contact with cylinders in daily life, but cylinders are common three-dimensional geometric figures, and children's consciousness is vague, so it is difficult to connect with society. By comparing the common cups and jars in life, children can find the particularity in the free expansion of play, so as to understand the specific characteristics of the cylinder. Therefore, children will be more interested. Due to various objective reasons, the children in our class are very different. Children with strong ability have good language expression ability, complete answers to questions and good observation. However, children with weaker abilities are very different. Therefore, this situation should be taken into account when designing activities. In the activity, I adopted the method of fostering strengths and avoiding weaknesses, and the children with strong ability acted together with the children with relatively poor ability to guide them to learn from each other. My activity is also to cultivate children's observation ability, so that children can judge the shape characteristics of cylinders through observation and comparison, and learn to perceive various cylinders with various senses. Finally, the children ended their activities in a happy "cart-pulling" game. The new "Outline" proposes to create a relaxed environment so that every child can participate in practical exploration activities and feel the joy of exploration and discovery. After the guidance of experts and continuous trial teaching and revision. I feel happy in this teaching activity.

The math teaching plan of kindergarten large class includes reflection: understanding the activity goal of the second cylinder

1, through touching, measuring, rolling, comparing and other activities, we can know the sphere and cylinder and distinguish their similarities and differences.

2, improve the ability of observation, comparison, imagination, analysis, synthesis and hands-on ability.

3. Develop interest in exploration and develop creativity and thinking ability.

4. Actively participate in mathematics activities and experience the fun in mathematics activities.

5. Stimulate children's interest in learning.

Activities to be prepared

1, prepare various balls. Such as ball, basketball, football, table tennis, glass ball, shot put, plastic ball, etc.

2. Prepare some cylindrical toys. Such as building blocks, plastic products, sticks, unused pencils, kaleidoscopes, etc.

3. Video about spheres and cylinders.

Activity process

First, ask the children to guess a riddle.

Fat, round, untenable, unstable, either side will roll. (sphere)

Teacher's summary: Many balls, although different in color, size and play, are all the same in shape. No matter which direction you look at them, they are round. They are always unstable and rolling on the ground. This is a ball.

2. Let the children measure an unused pencil, stick, kaleidoscope, etc. Look at the size of the circles at both ends and the distance between the two circles with lines, rulers and small hands, and talk about their findings.

Third, the teacher summed up: when measuring, there are two circles with the same size at both ends, and the vertical distance between the two circles is the same; When scrolling, you can only scroll in two opposite directions; Arranged vertically, it looks like a pillar. This is a cylinder.

Ask the children to take two toys (a ball and a cylindrical toy) and roll on the ground in the same way to see if they are different and can stop and stand firm.

Five, guide children to try to overlap two spheres and two cylinders, and observe the phenomenon.

Sixth, the teacher summed up: the sphere can roll in all directions, and the cylinder can only roll in two opposite directions; There are no planes on the sphere and they cannot overlap. There are two equal planes at both ends of a cylinder, which can overlap.

Seven, let children think about it, in kindergarten, home or other public places, what are the spheres? What is a cylinder? Talk about their names and functions respectively.

End of activity

Watch the video of spheres and cylinders.

Teaching reflection

Children are naturally curious and have a strong desire to explore and learn about things around them. The new syllabus emphasizes that science education should be closely linked with children's real life, and the things and phenomena around them should be taken as the objects of scientific inquiry. In daily life, children have actually come into contact with many spherical toys, such as rubber balls, corner balls, table tennis and so on, and are very interested in them. However, for children, it is difficult for them to fully understand three-dimensional graphics from the perspective of geometry, and they often confuse plane geometry with three-dimensional. So I designed this activity, so that children can feel the characteristics of the sphere through personal experience, experiment and operation, and gain scientific experience about the sphere. Stimulate children's interest in exploration and cultivate children's habit of caring about things around them.

Children in large classes have a strong desire to explore. They can communicate with their peers and adults in language and express their knowledge and feelings in their favorite way. Therefore, in order to meet the needs of children's cognitive, ability and emotional development. I confirm the objectives of the above activities.

From the design of this activity to the practice of this activity, I have a more thorough understanding of the design of teaching materials, and there are still many things to learn in the scientific field. In the future, I will read more textbooks, deeply understand the textbooks, walk into excellent teachers' classrooms, learn more new teaching concepts and methods, constantly reflect in practice and constantly improve in reflection.

Through after-class reflection, I found the following shortcomings:

1. When using the prepared materials to explore the difference between a circle and a ball, my purpose is to let children find their own way to distinguish the two, but in teaching, I ignored this point. Let the children tell directly by rolling, watching and touching. Therefore, there is a gap in the cultivation of children's learning methods. If, in the activity, children can find their own way, which not only develops their thinking ability but also achieves the purpose of the activity.

2. When I named my child to tell the difference between a circle and a sphere, I was too anxious. I didn't give my child enough time to talk, didn't take into account some activities of my child, and gave my child too little room for language organization and development.

In order to create a relaxed learning environment for children, I have prepared a lot of activity materials, but all kinds of materials have not played their role to the greatest extent. For example, let children distinguish the difference between a circle and a ball by touching, watching and rolling. Some children just watch, roll and touch very little. In particular, a small table tennis ball is prepared, and the characteristics of the sphere can be quickly mastered by grasping it with fists. I failed to remind the children in time.

4. Let children talk about spherical objects in life, with the purpose of making children feel that mathematics is around, mobilizing their life experience in life, and cultivating their thinking, speaking, observing and comparing abilities. There is not enough time for children in this link, so I am in a hurry.

5. I found that some children are not active enough to participate in activities, and they can only complete some activities with teachers and children, lacking creativity. In addition, some children operate too slowly.

In the whole process of children's exploration, discovery, perception, experience and development, as a teacher, I deeply realize that our role should be the organizer and leader of children's learning activities, and we should pay more attention to children's learning process and evaluation, encourage children to make new discoveries again and again, and fully experience the happiness of success.
