Symmetry of Mathematics Teaching Plan in Kindergarten Large Class

As a people's teacher who specializes in teaching others, he often has to write lesson plans according to the teaching needs, which is the joint point of the transformation from preparing lessons to classroom teaching. So do you know how to write a formal lesson plan? The following is my carefully arranged math teaching plan "Symmetry" for large classes in kindergarten. Welcome to share.

Symmetry 1 kindergarten big class math teaching plan

moving target

1. After a preliminary understanding of the phenomenon of axial symmetry, you can find the axis of symmetry on the symmetry graph.

2. Creation shows the beauty of symmetry through operation, and explores and discovers in operation.

3. Feel the symmetrical beauty of the surrounding things, improve aesthetic awareness and experience the fun of creative operation.

Activities to be prepared

1. Photo: Butterfly 24, scissors.

2. Rectangular and square paper.

Activity process

First, understand the concept of symmetry and feel the beauty of symmetry.

1. Illustration: Butterfly, symmetrical perception and understanding.

Teacher: Today, the teacher brought some pictures to the children. Do you want to see them?

Do you think these photos look good? Do you find the highlights in these pictures?

Children talk to each other. )

2. Teacher's summary: It turns out that the left and right sides of these patterns are exactly the same, like the shape, size and color of the left and right sides.

All the same. Let's call it "symmetry"

3. The teacher shows a picture to demonstrate that the picture is folded in half.

(1) Teacher: What if these symmetrical figures are folded in half? The same is true after folding in half. We call it "coincidence"-show the word card "coincidence"

(2) After overlapping, it is found that there is a broken line in the middle, and there is also a nice name called "symmetry axis".

4. Observe the physical pictures in life and feel the beauty of symmetry.

(1) Show butterflies, kites, masks, airplanes, etc. To perceive symmetry and find the symmetry axis.

Q: Are they symmetrical? Where do you see that they are symmetrical? Where is the axis of symmetry? )

(2) Why do people make these things symmetrical? What about things that look symmetrical?

(sense of balance, neatness and beauty)

Second, look for symmetrical objects around you and consolidate the understanding of the meaning of symmetry.

1. Show some items (binoculars, combs, clothes, mirrors, etc. )

Requirements: Choose symmetrical objects.

2. Children introduce their own things and talk about why they feel symmetrical.

Where is the axis of symmetry?

(Guide children to find that they can overlap after being folded in half, that is, symmetry)

Third, children's operation and creative performance are symmetrical.

1. Show your work (glasses)

Teacher: What do you think this is? Is it symmetrical?

Do you know what symmetry is?

2. Children's operation, explore folding symmetrical graphics with paper.

Fourth, the end.

Teacher's summary: Today, all the children in our class are very capable, not only knowing symmetry, but also folding symmetrical figures by themselves.

There are many symmetrical objects around us. Today, let's go home and see what else is symmetrical.

Can you come and tell the teacher tomorrow?

The goal of "symmetry" 2. Mathematics teaching plans for large classes in kindergartens;

1. Symmetry between shape and color was observed.

2. Understand the meaning of symmetry and you will find symmetrical operations.

3. Correctly judge the symmetrical figure and complete the exercise.

Activity preparation:

1. Items with symmetrical characteristics

2. Symmetrical card wall charts and various color graphics.

3. All kinds of graphics are packed in a paper bag, and children have an activity process:

First, perceptual symmetry.

1. Synopsis: Spring has come, the garden is full of colorful flowers, and beautiful butterflies are dancing happily among the flowers. At this time, a dark cloud came and butterflies were flapping their wings to go home. Suddenly, the butterfly cried: "I lost a wing and can't fly!" " "(arranging half a wing of a paper butterfly in the background picture) It's raining harder and harder. Who will help him find another wing?

2. Let each child pair the butterfly wings in the background picture.

3. Show the matched wings and explain the reasons for matching (same color, shape and size). Guide children to observe, compare and summarize the characteristics of these figures: the left and right sides are the same when folded, and they will overlap when folded together. ) teacher's summary: a figure that can completely overlap after being folded in half, such as a butterfly, has a center line, and its left and right sides are exactly the same in size, color and shape. We call it "symmetry".

Second, find symmetry.

1. The teacher shows half of a picture and asks the children to find the other half to spell it out.

2. Teacher: Actually, many parts of the human body are also symmetrical? Let's look for it. So can the movements be symmetrical? Please point out and perform. )

3. What else have we seen that is symmetrical? Doors and windows, bees, dragonflies, butterflies, books, clothes, hearts, trapezoid, palms, faces, airplane wings, wheels, etc. )

Third, practice judging several groups of pictures in the book (show the self-made wall chart) and see which group of pictures are symmetrical. Just tick "√" in the box below.

Fourth, pour out all kinds of graphics in the game paper bag and find out which graphics are symmetrical respectively. Spelling on the table, the teacher will patrol the guidance.

Five, homework after the completion of the workbook (P20)

The goal of the activity is "symmetry". 3. Mathematics teaching plan for kindergarten large class;

1. Understand the meaning of symmetry, and you can correctly judge whether the graph is symmetrical.

2. Be able to swing correctly and draw the other half that is symmetrical with the figure, and feel the symmetry of the figure initially.

3. You can use the method of folding in half to cut out symmetrical figures and feel the beauty of symmetry.

4. Develop visual perception and judgment.

5. I like math activities, and I am willing to participate in various arithmetic games to cultivate rebellious thinking.

Activity preparation:

Whiteboard courseware, operation paper, scissors, small basket.

Activity flow:

First, the story is imported.

Teachers tell stories to create situations and stimulate children's interest in activities.

Second, save the queen.

By creating a situation to break through obstacles, we can break through the important and difficult points of teaching.

1. By understanding the meaning of symmetry at the first, second and third levels, we can correctly judge whether the graph is symmetrical or not. (key)

Level one: find it.

Teachers restore love by showing half of love and inspiring children to find the other half.

Teacher's summary: Figures with the same size and shape on the left and right, which can completely overlap after being folded in half, are called symmetrical figures. This straight line is its axis of symmetry.

Level 2: 10% discount

Use hand folding to judge whether the figure is symmetrical, encourage children to explore and find that the same shape is symmetrical and the number of symmetry axes is different.

The teacher summed up: It turns out that in symmetrical figures, some have only one axis of symmetry like a semicircle, while others have several axes of symmetry like a square.

The third level: one point

Please separate them, put the symmetrical ones in the smiling face box and the asymmetrical ones in the crying face box.

2. Through the fourth level and the fifth level, we know that the distance between two symmetrical squares and the axis of symmetry is equal. (difficulty)

The fourth level: put a pendulum.

Let the children swing the F squares so that they are symmetrical with the pattern on the left.

Level 5: Fight.

Let the children work together in groups of six, and spell a little soldier on the left that is symmetrical with the little soldier on the right.

3. A gift from the Queen

Show pictures of the queen and introduce that the kingdom of the queen is called "symmetrical kingdom".

Show pictures of gifts and guide children to completely change gifts.

Activity expansion:

Jane Jane

Let the children take the gifts back to the classroom and cut them.

Activity reflection:

Children in large classes are more and more eager to explore. In this activity, the form of breaking through obstacles was designed, which greatly attracted children. Through the activities, I deeply reflected and gained a lot:

1. This connection is obvious.

The whole process of the activity is clear, with the task of saving the queen as the definition, and four difficulties are designed, namely, "finding symmetrical love-folding symmetrical figures-dividing symmetrical objects-posing symmetrical figures", and each level has learning and practice about symmetry; In the specific link of teaching, it is also a very prominent feature to let children participate. The origami game effectively increases each child's participation and successful experience.

2. The combination of electronic whiteboard and PPT.

The various functions of whiteboard provide beneficial help for children to understand symmetry. It completely replaces the blackboard, breaks the restriction that teachers can only sit in front of the computer and use the mouse when using multimedia courseware, gives teachers more room to play, makes teaching more vivid, improves learning efficiency and learning effect, changes the traditional education mode, and gives children more knowledge and interest in learning.

Encyclopedia: Symmetry is the regular repetition of the same part of an object.

The activity goal of Symmetry 4, a math teaching plan for large classes in kindergarten;

1. Feel the symmetry of the graph.

2. Understand the meaning of symmetry and correctly judge whether the figure is symmetrical.

3. Draw the other half that is symmetrical with the object according to the existing figure provided.

4. Guide children to actively interact with materials and experience the fun of mathematics activities.

5. Interested in participating in math activities.

Activity preparation:

1. Children should have a piece of homework paper (square, trapezoid, crescent), semi-graphic homework paper and scissors.

2. Teacher's operating materials: square, trapezoid and crescent.

courseware

Activity flow:

First, story introduction: stimulate children's interest.

1. Teacher: There lived a kind princess in a kingdom. One day, an evil wizard came to the kingdom. She locked up the princess and set up five difficulties. People want to save the princess, but they can't get through these difficulties. Son, are you willing to break through many difficulties to save the princess?

Second, understand the significance of symmetry in exploration, perception and judgment.

The first level: find a symmetrical red heart

Level 2: 10% discount

The third level: looking for symmetry

The fourth and fifth levels: draw symmetrical figures.

Third, make symmetrical graphics.

1. Requirements: There is only the other half of these gifts. Who can make them complete?

2. Pediatric surgery

Fourth, extension.

1. Do you know the name of this kingdom? (Kingdom of Symmetry)

2. There are many interesting symmetrical figures in the kingdom of symmetry. Let's play Symmetry Kingdom next time, shall we?

Activity reflection:

The goal of this activity has been basically completed, and the whole activity is clear and smooth, which can guide children to understand the meaning of symmetry step by step and educate them in the game. During the activity, I gave the children a space for their own exploration and practice, which reflected their position in the activity. Of course, some small details need to be improved:

1. When children operate with a pen, they should be asked to move the chair to the upper position and sit on the small chair, which is helpful for children's operation.

2. The three numbers of the first level should be marked to help children find it accurately.

3. In the process of operation, the graphics of the fifth painting are a bit complicated, which can be simplified appropriately.
