Teaching plan of "graphic transformation" in large class

As an excellent teacher, we must carefully prepare lesson plans, which are the basis of teaching activities and have an important position. How to write the lesson plan? The following is the teaching plan of Graphic Transformation that I collected for you. Welcome to reading. I hope you will like it.

"Graphic Transformation" large class teaching plan 1 1. Activity objectives:

1, in the repeated changes of graphics, train children's thinking and improve their operational ability.

2. By making children change triangles, squares, trapezoids, circles and other figures repeatedly, guide children to find that the figures can change and transform with each other, and can be changed into different numbers of various figures.

3. Cultivate children's interest in combining various graphics into various objects.

Second, the activity preparation:

1. Teaching aid: triangle, rectangle, trapezoid and circle are combined into a picture (robot).

2. Learning tools: each person has a set of paper with various graphics and puts it in an envelope.

Third, the activity process:

(1) Beginning: Little friend, do you know what the teacher is holding? (The teacher takes out a wall chart with his back to the child), change it! An art exhibition appeared in front of the children. "Robot" Yes! Then look at what robots are made of. "Made of graphics." All right! Let's play a game about graphics.

(2) Basic part:

The first attempt: observation and thinking.

L, let the children use their brains and carefully observe what graphics the robot is made of? It consists of a circle, a square, a triangle, a rectangle and a trapezoid. )

2. How many numbers are there in each type? (6 circles, 6 semicircles, 1 square, 4 rectangles, 5 trapezoids and 1 triangle. )

The second attempt: use origami game to see the change of graphics.

1. Gift: (Learning tool) Children, everyone has done well in the above games, and the teacher should reward them. Every child has a gift (school supplies). I know everyone wants to see what presents are in the bag. Ok, please open the small envelope yourself (there are many colors of graphics in it). Do you like it? ("I like it!" ) these small numbers are still amazing. If you fold them by hand, they will become other shapes. Try it if you don't believe me.

2, operation: use your hands and brains to perceive the graphic transformation.

(1) Let the children make a change by hand (origami).

(2) Let children talk about the results of change:

Square-divided into triangles and rectangles.

Round-semi-circular, fan-shaped.

Rectangular-into triangles and squares.

(3) Conclusion:

Multicolored graphics are full of fun: Are these little graphics interesting, children? (fun! ) Then if we stick it on white paper, it will become a beautiful sticker. Give these photos to your parents. Teachers and students enjoy the joy of hand-making.

Four. Extension of activities:

Let the children go home and find out with their parents which things in your home are the graphics you know.

Five, the focus of the activity: master the graphic essentials.

Activity forms of intransitive verbs:

(No) Now, the teacher will play a little magic trick with you! Look what will happen to this board! Preparation: (magic change, yo! Look at the back and then at the front, and a "robot" is created. Is it beautiful? Do you like it? Then look at what robots are made of. "Made of graphics." All right! Let's play a game about graphics.

(2) Basic part:

The first attempt: observation and thinking.

L, let the children use their brains and carefully observe what graphics the robot is made of? (It is composed of circles, squares, triangles and rectangles. )

1. Gift: The child speaks very well and the teacher will reward you. Every child has a gift (school supplies). I know everyone wants to see what presents are in the bag. Ok, please open the small envelope quietly (there are many colors in it). Do you like it? ("I like it!" ) these small numbers are still amazing. If you fold them by hand, they will become other shapes. If you don't believe me, please try it with your parents.

2, operation: use your hands and brains to perceive the graphic transformation.

(1) Ask parents and children to make a change (origami).

(3) Conclusion:

Multicolored graphics are full of fun: Are these little graphics interesting, children? (fun! ) Then if we stick it on white paper, it will become a beautiful sticker. Give these photos to your parents. Parents and children * * * enjoy the joy of handmade. (music),

(4) Activity extension:

Let the children go home and find out with their parents which things in your home are the graphics you know.

Reflecting on this activity after class, I am generally satisfied. The lesson of "Graphic Transformation" is relatively novel, and children are more interested in learning. Especially before class. Stimulate children's interest in learning and develop their thinking and imagination through magic and gifts. Throughout the class, the children learned happily and developed their practical ability. With the cooperation of my parents, they successfully completed my request.

Through the class, I found that there are also many problems that have not been considered in the actual teaching:

1, the child's operation ability is overestimated, and the child's operation time is longer than expected.

2, the child's language expression ability is weak, I can't describe the operation process in complete language, and even the description and operation are a little inconsistent.

Activity reflection:

Generally speaking, this activity is quite satisfactory. Various graphics selected in the activity "Graphic Transformation" are common basic graphics in children's life, such as triangle, square, rectangle, trapezoid and circle. In the activity, show different graphics, let children identify the graphic features, then identify and count them in the robot patterns, and finally master the graphic features through puzzles. The way of activities is suitable for the development characteristics of children of this age, and children are interested in learning. Through the full preparation before class and the exploration and observation of children, we can boldly operate and find different transformations between graphics, and on this basis, we can inspire children to apply jigsaw puzzles to combine various vivid images. In the process of communication, children actively use their brains, boldly express their views through observation and reasoning, and then verify them by guessing. Throughout the class, children are interested in this and give full play to their hands-on ability in the operation. This activity can successfully complete the objectives set by the activity and achieve good results.

At the same time, there are also problems that have not been taken into account in preparing lessons in this practical teaching:

1, the child's operation ability is overestimated, and the child's operation time is longer than expected.

2, the child's language expression ability is weak, unable to describe the operation process in complete language, and the expression is too casual and simple.

3. The lead-in period is too long, resulting in unnecessary waste of time.

4. Due to the limitation of conditions, we failed to make full use of the courseware for detailed demonstration and guidance.

Through this activity, children master the characteristics of different plane graphics, and can find different graphics in different patterns and learn to count. Then, by doing puzzles by myself, I further mastered the characteristics of graphics.

The Design Intention of "Graphic Transformation" Teaching Plan 3 in Large Class;

Through children's understanding of graphics, we can know the changes between graphics. How to let children spell out their favorite shapes with geometric figures? The science education activity "Graphic Change" is an extension on this basis, aiming at improving children's puzzle skills and enriching children's imagination by choosing different geometric figures.

Activity objectives:

1. By changing the shape such as triangle, square, trapezoid, circle, etc. , can guide children to discover the mutual changes and transformations between shapes, and can produce different numbers of various shapes.

2. Cultivate children's interest in combining various graphics into various objects.

Activity preparation:

1. Teaching aid: triangle, rectangle, trapezoid and circle are combined into a robot painting.

2. Learning tools: each person has a set of paper with various graphics and puts it in the learning tool bag.

Activity flow:

First, the introduction.

Today, I brought a friend. Guess who it is? (The teacher shows the picture) Who is he?

Second, observe and think.

1. Please have a look. What is this robot made of? (composed of circle, square, triangle, rectangle and trapezoid)

2. How many numbers are there in each type? (4 circles, 4 squares, 1 rectangle, 2 trapezoid and 1 triangle)

Third, start origami and observe the changes of graphics.

1. Now, I want to take out the graphics on the robot. There are other magical changes in these graphics.

2. The teacher demonstrates the graphic squares, and the origami becomes triangles and rectangles.

Fourth, use your hands and brains to perceive the transformation of graphics.

I have many small numbers here, and they are still amazing. Just fold it by hand and it will become other shapes. Do you want to have a try?

1. Let the children change it by hand (origami)

2. Let the children talk about the result of change: a square-a triangle and a rectangle; Round-into a semicircle and fan; Rectangular-into a triangle or a square.

Fifth, the ending part.

Multicolored graphics are fun, children. Are these little figures fun? Then let's make them into a robot and count which shapes your robot is made of, and how many are there in each shape.

Science in Big Classroom —— Graphic Transformation

Teaching reflection:

The "graphic change" of science education activities is carried out step by step. By choosing different geometric figures to spell out shapes, children's imagination and creativity are greatly enriched. The biggest highlight of the whole activity is that in the process of children choosing geometric shapes, teachers only give full play to children's dominant position on the basis of supporters, so that children with strong abilities can help children with weak abilities in the activity, which is also conducive to cultivating children's cooperative spirit. From the whole activity process, the children's enthusiasm and initiative have been fully reflected. But there are also some shortcomings. When children are making robots, they don't know how to use the geometric figures in their hands, and they can spell out robots by folding and tearing paper.

2. Work exchange

(4) Activity extension:

Let the children go home and find out with their parents which things in your home are the graphics you know.

Activity reflection:

The design idea of "graphic transformation" in the comprehensive activities of large classes is that the children in large classes have already known rectangle, square, trapezoid, triangle, circle, semicircle and ellipse, and have developed a strong interest in geometric graphics. This activity is an attempt to combine the field with the art field. The activity takes the birthday of the graphic doll as the theme, and helps children to further perceive and master the basic characteristics of geometric figures through listening, watching, finding, cutting, spelling and speaking. Fully mobilize children's various senses and satisfy their desire to explore and try to create, which is in line with the age characteristics of large classes.
