The math teaching plan of kindergarten middle class "ellipse" 1 activity name: understanding ellipse.
Activity goal: to know the ellipse and perceive its basic characteristics.
Activity preparation:
Teaching AIDS: one round and one oval, and one piece of paper.
Learning tools: a circle and an ellipse with the same size as a human hand, and a piece of paper (the same length as the diameter of the circle); The first and second groups, color the ellipse; Groups 3 and 4, mark the most dots with "*". Groups 5 and 6: Look at the symbols and fill in the dots.
Activity process:
I. Group activities
1, know the ellipse.
Show the oval. "Is it round?" (No) "Where do you see that it is not round?" "Let's compare." (Guide children to compare the two figures in front of each other, and confirm that the ellipse is longer than the circle. "So what is the name of this figure?" (Ellipse) "Besides being longer than a circle, where is the ellipse different from a circle?" (Guide children to fold the circle left and right first, then fold it up and down, and measure the folds twice with paper strips to verify that the two folds of the circle are the same length; Then guide the children to fold the oval in half up and down, and measure the folding marks again to verify that the folding marks of the oval are not the same length.
2. Summarize the characteristics of ellipse.
"The two ends of the ellipse are longer than the circle, and the folds folded up and down and left and right are not the same length."
3. Name the oval-shaped objects in daily life.
"What else do you see at home and in kindergarten that looks like an oval?"
Second, group activities
1, the first and second groups, color the ellipse.
"Find out the ellipse and paint it in the same color."
2. In the third and fourth groups, mark the most ideas with "*".
3. Groups 5 and 6, look at the symbols and fill in the dots.

4. Interested in taking part in math activities.
Activities to prepare
Material preparation: PPT, mother bear, sister bear, oval mirror picture, circle, operation book.
Activity process
1. Introduce activities in the form of storytelling.
Lead: "One day, Mother Bear and Sister Bear went shopping together. They saw many mirrors hanging in a shop and went in. Sister Bear took Mother Bear to a mirror and asked, "Mom, this mirror is really strange!" "
2. Guide children to understand the basic characteristics of the ellipse.
(1) Show the oval mirror picture and ask the children to play freely.
(2) Show the circle, so that children can feel the difference between ellipse and circle.
3. Summarize the characteristics of the ellipse, focusing on guiding children to express the basic characteristics of the ellipse in language.
(1) The two ends of the ellipse are longer than the circle.
(2) Folding up and down and folding left and right are not the same length.
4. Guide children to say the oval-like objects in daily life.
5. Distribute the operation book and explore the operation for children:
(1) guides the classification by color.
(2) Guide children to sort by size.
(3) Help children to further understand the ellipse in the form of games.
6. Children's operation, teachers patrol and guide and focus on guiding children with weak ability to operate.
7. The teacher evaluated the operation of this activity.
Teaching reflection:
This activity class of knowing the ellipse is over, and I feel that the child has learned at least the goal has been achieved. My activity is to let children learn to know graphics in a relaxed environment. I made full preparations before class and arranged it according to the characteristics of the children in our class. The children in our class are very lively, so we can't use the boring teaching mode. I want children to learn and explore in the mode of alternating static and dynamic. The whole design process of this activity is good, but there are some mistakes in asking questions to children, and the questions are always inaccurate. Some questions are too adult, which is my shortcoming. There are also problems that sometimes occur in the course of class, and the teacher is not sure enough. This is where I should pay attention.
The third activity goal of "Ellipse", a math teaching plan for middle class in kindergarten;
1.Develop visual acuity and judgment.
2. Learn to correctly perceive the ellipse in comparison with the circle.
3. According to its characteristics, the ellipse can be found in many figures.
4. Guide children to actively interact with materials and experience the fun of mathematics activities.
Activity content:
Interesting oval.
Activity preparation:
1.A set of square, rectangle, triangle and circle cards.
2. A courseware (a picture of Miss Qiu giving a gift).
3. A set of round and oval cards is available.
4. Operate paper and oil pastels.
5. Physical objects: boxes, plates, leaves, apples, lemons, eggs, baskets, etc.
Course record:
I. Import activities
Review the graphics you already know.
Teacher: "Look, who's coming?" (Show the picture of Miss Qiu giving a gift).
Young: "Miss Qiu."
Teacher: "Autumn has come, and Miss Qiu has sent us many gifts. Let's see what presents we have together.
Young: "There are cookies."
Teacher: "What shapes are these biscuits?
Young: "This is a triangular strawberry biscuit."
Young: "There are square apple cookies."
Young: "There are also rectangular banana-flavored biscuits."
Young: "and round orange cookies."
Comment: Let the children review the graphics they already know through the gift given by Miss Qiu, so as to prepare for learning and understanding the ellipse.
Second, know the ellipse.
Teacher: Please take out the two cards (round and oval) in your hand and find out which one is the long round and the flat round.
Young: This circle, which is longer than a circle, is oval.
Teacher: We call this long, flat circle an ellipse.
Comment: according to the teacher's prompt, children can compare the circle with the ellipse and find out the long, flat circle.
Third, compare circular and elliptical.
(1) Compare the same points. Ask children to touch the edges of a circle and an ellipse, and guide them to observe and find the same point: they have no corners.
(2) Distinguish the differences. Place the centers of a circle and an ellipse on top of each other for children to compare and observe, and then ask children to fold their two figures in half from the center, top, bottom, left and right, and a "ten" fold appears on each piece of paper. What are the differences between the four folds of a circle and an ellipse?
Comment: Through operation and exploration, children actively learn to find out the similarities and differences between round and oval, creating a relaxed and pleasant psychological atmosphere for them and creating conditions for children to play their subjectivity.
Fourth, find an oval.
Show boxes, plates, leaves, apples, lemons, eggs, baskets, cantaloupes, etc.
Teacher: The naughty oval is going to play hide-and-seek with us. Let's find out what looks like an oval.
Young: eggs are oval.
Young: The face of the box is oval.
Young: The leaves are oval.
Young: The bottom of the basket is oval.
Young: cantaloupe is oval.
Young: The plates are oval, too.
Comment: oval. By showing objects, children's interest in learning is further stimulated, and children can communicate freely with their peers in a relaxed atmosphere, which not only exercises their oral expression ability, but also enhances their confidence in speaking boldly.
Fourth, color the oval baby.
Guide children to find the ellipse in the picture composed of geometric figures and color it.
Comment: Children's interest in operation is high, their initiative and enthusiasm have been fully mobilized, and they have gained learning experience through exploration.
Area corner activity: put squares, rectangles, triangles, circles and ellipses in the science corner, so that children can combine various objects with graphics.
Teachers' self-evaluation: The whole activity has clear objectives, clear levels, interlocking, and advancing layer by layer, achieving the expected goals and effects.
Director's comments: Children distinguish the difference between a circle and an ellipse through observation, comparison and analysis, and know the ellipse. They can correctly grasp the names of the circle and the ellipse, and understand the characteristics of the ellipse. In the operation activities, children can operate according to the requirements of teachers, and their operating habits are good. In the whole activity, children's routines are also very good, and they can actively raise their hands to answer questions, which makes them interested in activities. Teachers inspire and guide children to fully mobilize their enthusiasm for learning, and use "games" to run through the activities, so that children can gain knowledge and experience in playing, which truly reflects the fun of playing and learning.
Activity reflection
The goal of this activity is to perceive the difference between circle and ellipse and understand the main characteristics of ellipse through operation. Improve observation ability and comparison ability.
Guide children to say the oval-like objects they have seen in daily life. Find out what other oval objects you have seen in the classroom and kindergarten, and record them in groups to share with your peers. Children gain not only the roundness and ovality in their activities, but also how to distinguish the differences between them.
Design intent
Mathematics is an abstract and thinking subject, and games are the best way for children to learn. In this math activity, the teaching objectives and contents are skillfully integrated into it, and children are boldly tried to actively participate in the operation, further understand the ellipse and cultivate children's divergent thinking. Let children fully experience the fun of activities and truly "play with learning" and "play with learning". Cultivate children's good operating habits and stimulate children's enthusiasm for participating in mathematics activities.
Encyclopedia: An Ellipse is the locus of a moving point P whose sum of the distances to fixed points F 1 and F2 in a plane is equal to a constant (greater than |F 1F2|), and F 1 and F2 are called the two focuses of the ellipse. The mathematical expression is |PF 1|+|PF2|=2a(2a> |F 1F2|）。
The teaching plan "Ellipse" in the middle class of kindergarten 4 Activity objectives:
1, develop visual perception, judgment, and find the ellipse in life.
2. Learn to correctly perceive the ellipse in comparison with the circle.
3, according to its characteristics in many graphics to find out the ellipse, learn to know the ellipse.

4. Music.
Key points and difficulties of the activity:
Focus of activities:
Know the ellipse.
Activity difficulty:
Looking for the ellipse in life, using the ellipse to create and operate.
Activity process:
First, the finger game "Finger Change" introduces the theme.
1, play the game of changing fingers with children.
2. Magic with hairy roots (all kinds of oval things)
3. Review the known figures (square, rectangle, triangle, circle).
Teacher: There is a new graphic baby in our class today. Who is it? Do you want to meet new friends?
Let's make it out together, shall we? Gollum changes and the oval baby comes out. Hello, children. I'm an oval baby. Nice to meet you. The oval baby is very polite. Should we say hello to it, too?
Second, understand the characteristics of the ellipse.
1, Teacher: I have two figures here, one is round and the other is oval. What's the difference between them? Find out which one is the long circle and the flat circle. (The circle is a little round, and the oval is a little longer than the circle)
Teacher: We call this long, flat circle an ellipse.
2. Ask the children to tell us which things in our lives are oval.
Third, look for ellipses.
1, show the prepared props, there is also an oval here to see who can find it first.
Teacher: The naughty oval wants to play hide-and-seek with us. Let's find out what looks like an oval.
Show plates, leaves, apples, eggs, sugar, bread, stones, etc.
Fourth, children's puzzles and comments.
1, the teacher demonstrated various graphic stick figures on the blackboard.
2. Put the prepared graphics together into a picture.
3, children's operation teacher guidance.
4. Show children's works and encourage them.
Teaching reflection:
This activity is a math activity. First, show different graphics, so that children can recognize the graphic features. The whole class has clear thinking, complete design and active atmosphere. Perceive the difference between circle and ellipse, and understand the main characteristics of ellipse. Improve observation ability and comparison ability. Guide children to say the oval-like objects they have seen in daily life. Children gain not only the roundness and ovality in their activities, but also how to distinguish the differences between them. Children can boldly imagine and name the corresponding graphics according to the guidance of teachers, find different graphics in different patterns, and then master the characteristics of graphics by doing puzzles themselves.
Shortcomings:
Language is not friendly enough, lack of affinity, children's hands-on operation and pasting time is long, lack of language to encourage children, and seeing that children can't finish their works within the specified time, they are very helpless, lack of guidance for individual children, and their language is not refined. There are many places to improve and more studies are needed.
