Teaching tool picture
Activity process
First, import
Introduction: "children, there are several graphic babies in our class today." Let's go and have a look together? "
Show the children around the shops made of round objects and talk about their faces.
Summary: The faces of these objects are all round. So what kind of figure is round?
Second, expand
1, each child has a circular card to guide children to observe and explore the shape characteristics of the circle.
Each child has a round card. Please touch it along the edge of the circle.
Q: How do you feel? Let the child touch the round face and ask: How do you feel?
The edge of the circle is smooth and the surface of the circle is flat, and the shape characteristics of the circle are preliminarily perceived.
Summary: The surface of a circle is flat, and the periphery is smooth and angular. Such a figure is a circle.
2. Observe the expansion and find the circle around you.
Please look for the circle around you: What is a circle in our classroom?
Have you ever seen a round object there?
3, courseware observation, perception of the circle in life.
Teacher: Please have a look. Which of these items are round?
4, the game "send graphic baby home"
Methods: The child has a triangle and a round card, and the teacher prepares two cards for the graphic mother.
After guiding the children to observe for themselves, send the graphics in their hands home and say, "I will send xx graphics home".
Finally, the teacher leads the children to check and verify.
Third, the conclusion part.
Children, did you have fun with the round baby today? Let's have a look outside the classroom. Those things are round, too, shall we?
The teacher leads the children to look for round objects, and the activity is over. )
Understand the teaching plan of the second part of the circular small class;
1, let children perceive the graphic circle.
2. Create a pleasant game plot, use a variety of senses to mobilize children's thinking and imagination, develop children's observation ability, and stimulate children's desire to explore.
Activity preparation:
Small CD-ROM, multimedia courseware.
Activity flow:
First, import
Teacher: The teacher brought a good friend today. Do you want to see him? Let's invite it out.
What is it like?
Round and smooth. It has a nice name called Yuan.
Please say it with me, circle.
Second, new funding.
Teacher: Children, please take a circle out of the box and touch it.
Smooth and round. Please put the circle back in the box.
Let's have a look, children. Is there anything round in the classroom?
2. Teacher: The teacher also found many round things in our life. Let's have a look! (show PPT)
Show them in turn: ball, coin, plate, clock, bubble, wheel, button, biscuit, chocolate bean.
Third, the game
Combine the figures and spell out the patterns that children like with circles.
Understand the design intention of teaching plan 3 of circular small class;
Children in small classes are easily dominated by external things and emotions in the cognitive process. Inadvertent memory is dominant, and people tend to remember things unintentionally. Games and operations are children's favorite activities. If children simply know the circle, they will feel bored, their interest is often not high, and the effect is not good. Therefore, when designing this kind of teaching activity, let children know some common round objects and features in the game operation, so as to stimulate children's interest in observing and exploring things around them and develop their abilities of perception, observation and imagination.
Activity objectives:
1. Grasp the characteristics of the circle in cognition, operation and game activities.
2. Look for round objects in the surrounding environment and perceive the application of circles in life.
3. Cultivate children's observation and imagination.
4. Willing to try boldly and share experiences with peers.
5. Stimulate children's interest in scientific activities.
Activity preparation:
1, the activity room is decorated with some round objects.
2. A round piece of paper and some round objects (such as mirrors, bottle caps, tambourines and plates).
3, slides, each table has a box, there are all kinds of round items in the box, some operation paper, a marker.
Activity flow:
First of all, create a situation and know the round object.
Teacher: (with mysterious tone and eyes) Today, the teacher brought a box of toys to the children. Please take one to play on the table. What is this?
The mirror I took,
I took the tambourine,
Yang: I took the plate. ...
Teacher: What did you find? What do these things have in common?
Yang: They are all round. (bring up the topic of the circle. )
Teacher: (showing a round piece of paper) Question: What is it like?
Yang: It's like a plate.
Yang: Just like the sun.
Second, the characteristics of perception circle.
Teacher: Let children choose a round object and touch it along the surface and edge of the object to exchange feelings with each other.
Young: generally,
Young: round,
Yang: The edges are smooth.
Young: no edges and corners ... (children communicate and fully express their views)
Teacher: Tell me, what else have you seen that is round? Encourage children to tell the round things they see at home or elsewhere.
Yang: Bowl, basin, ball, lamp. ...
Third, observe the slide "acrobatic performance"
Teacher: Say, who is on the screen? What are they doing?
Teenager: Qiqi, Lele, Huanhuan, Bear.
Yang: They are playing acrobatics.
Teacher: Think about it. A circle can do somersaults, but why not a square circle?
Yang: It's not only a square circle, but also an angle that can't be turned over. (Guide the child to say)
Teacher: Have a look. What shape are the wheels of a unicycle? What else is round?
Young: round, (children say together)
Yang: And balls, hula hoops, rolling circles and plates.
Fourth, make a circular mark.
Give each child a piece of white paper (with a circular hole around it), guide the children to tear it into a circle along the hole, and then let the children draw something they like on the circular paper or make a mark, and then stick it on their own things as a sign.
Five, looking for round items
Guide children to look for round objects in the activity room and ask them to express them in words, such as "I found them: they are round". And put it in the math activity area regularly.
Activity expansion:
Prepare some paper with circles for your child, inspire your child to add a few strokes to the circle and turn it into another pattern (such as the sun and apples), and encourage him to draw as many as possible.
Teaching reflection:
1. Through the activities in this lesson, children can distinguish circles from many objects and find round objects in life through observation.
2. In this class, I was relatively successful and achieved the expected teaching purpose. I followed the characteristics of children's age, taking children's interests as the starting point, and introduced the theme of today's activity-understanding the round world through the bubbles that children like. Children can participate in it according to the guidance of teachers and learn about the round step by step. However, I think my language is not childlike. Some words are a little blunt, and children can't understand them, which leads to a little unsmooth activity process in the class. I must listen to other teachers' lessons more, integrate their teaching languages, and finally form my own unique teaching language.
3. If I take this course again, I will use courseware to show all kinds of circles and design bubble blowing games to let more children participate, because in my opinion, bubbles displayed through courseware are more vivid and attract children's attention, and designing bubble blowing games can arouse children's participation interest.
Understand the teaching plan of circular small class 4 I. Activity preparation:
1. Cut all kinds of colored paper into large and small circles and stick them on the magnet blackboard. Scissors, paste, round stickers, drawing paper, magnets, colors, etc.
2. Children's math books.
Second, the activity process
(1) Tell the story of Bobo, who loves painting, to arouse interest.
Let the children guess what Bobo drew with the story. "Uncle Pig drew many large and small circles. My brother and sister watched them for a long time. I didn't know what Bobo's circle was, so I asked Bobo, "What is the circle you drew? "Bobo said," There are two hands in this circle, one is long and the other is short, and they go around from morning till night. My brother said, "Oh, I see, it's a clock." "My sister said," what is this? "Bobo said:" There is still a long line below, so we should grasp it well and don't run away. My sister said, "Oh, this is a balloon." . "Brother and sister finally know what Bobo painted. Bobo drew many circles, even the circle of navel. Mother said, "Bobo is really a great painter. "
(2) Let children do puzzles by operating methods.
Children are bobo, too. Use round colored paper to put together a collage and see what shape you can put together. Ask the children to appreciate the works and encourage them to talk about what they make with round collages.
(3) Lead children to open the first page of My Mathematics, inspire children to observe the contents of the picture, let children draw circles with their favorite colors, and then talk about what is round in the picture.
(4) Guide children to observe the surrounding environment and think and talk about what is round in life.
Three. Activity objectives:
1. Know this circle and use it to create shapes.
2. Develop children's imagination and operational ability.

3. Teachers and children discuss the characteristics of a circle Teacher: What does a circle look like?
4. Life is round: there are many round things in life. We also have them in our classroom. Did you find it? ! Have you ever seen those round things? Say it.
Teaching reflection:
Lack of passion in the teaching process, mathematics itself is boring, so when teaching new knowledge to children, teachers need to use their passion to drive children's learning, and pay attention to this aspect in future teaching.
Understand the background of activity design of teaching plan 7 in circular small class.
Children in small classes have a little simple concept of geometry, and children at this stage can correctly understand circles, triangles and squares through the guidance of teachers. But they don't recognize these shapes from their characteristics, but compare them with familiar objects in daily life. Therefore, I let children become interested in graphics in game exploration, and perceive the different characteristics of graphics through observation, comparison, imagination and other forms.
moving target
1, let children compare and perceive the basic characteristics of graphics, and create a pleasant game plot.
2. Use a variety of senses to mobilize children's observation ability of thinking and imagination and stimulate children's exploration ability.
3. Guide children to actively interact with materials and experience the fun of mathematics activities.
4. Stimulate children's interest in learning graphics.
5. Develop children's logical thinking ability.
Teaching emphases and difficulties
Understanding and difference between circular triangle and square
Activities to be prepared
Pictures of small animals, pictures composed of geometric figures, and several cards of three geometric figures.
Activity process
1. The kindergarten teacher will take you to make a puzzle today. Would you like to do it? In the future, I will show all kinds of pictures composed of these three pictures to children to stimulate their interest. I will continue to pose with children through imagination.
2. ask questions; There are so many beautiful graphics. Do you know what patterns they are made of?
3. After the children answer, I will tell the children the characteristics and names of the three figures in the form of nursery rhymes according to their answers.
Let children know three kinds of graphics in the form of games.
1, game; Touch it to let children understand the difference between these three kinds of graphics in the form of touch, and say the names of the graphics.
2. games; Whose ability is great. Show all kinds of patterns made of graphics, and let children find out what graphics are made of.
3. games; Small animals find homes. Show pictures of small animals, and I will tell the children that they are crying because they can't find their home. Please help them find their home. For example; I will play a small animal and talk about the shape of my house, and ask the children for help.
4. games; Looking for graphics baby. There are three graphic babies on the classroom floor. I called the password to let the children find the graphic station and see who can find it quickly and well.
End. Today, we had a good time. Can the children tell the teacher which graphics you know and what their characteristics are? Go home and observe. Things in your home are made up of figures we know today. Tell the teacher when you come tomorrow.
Line up to play songs and take the children to the bathroom.
Teaching reflection
In the actual teaching process, I saw this phenomenon from children:
1, children are very interested in all kinds of graphics, children have a keen observation of things around them, and have a desire to know about graphics babies.
2. In the activity, children are very active, and they can actively tell their teachers and friends around them about their findings, so that their expression ability, reaction ability and observation ability have been developed.
I also learned from the child's operation that the child is willing to participate in this activity and actively look for it. Children are interested and willing to take the initiative to explore and participate. I think my original design can be adjusted to: children have insufficient time for self-operation, no opportunities for children to cooperate and communicate, and the language needs to be refined. In the process of organizing activities in the future, I will improve it, convey a good sense of language for children and cultivate their expressive ability.
