Teaching plan for large class mathematics activities: finding a home by graphics 1 design intention;
According to middle school students' cognitive, operational and logical thinking abilities, they are constantly improving. At the same time, they are not only satisfied with what the teacher said and taught, but also hope that their abilities will be confirmed. So they are very interested in their own exploration and operation. Nowadays, middle school students have classified colors and things separately, but it is a bit difficult to divide things and graphics twice. Mathematics is an abstract logic subject. When I choose the math activity of "finding a home with graphics and classifying it twice", I consider that teachers are used to emphasizing only intuition, which is based on the characteristics that children know things from concrete to abstract. In activities, teachers often use teaching AIDS to demonstrate and explain mathematical concepts on this basis, but in fact, the formation of children's mathematical concepts can not be solved by teachers' lectures and watching teachers' demonstrations, but by the process of children's independent exploration and operation. So in this class, I use the introduction of games and the links between multimedia teaching and children's operation to let children learn the secondary classification of graphics in the process of exploration and operation in a relaxed and pleasant atmosphere.
Activity objectives:
1, learn to look at colors and shapes to classify graphics twice.
2. I will sort out my math data.
3. Experience the fun of math games.
Activities to be prepared
Teaching AIDS: 1, secondary classification board 2, green, red triangle, circle and square 3, courseware PPT.
Learning tools: 1, each person has an operation board, 2, each person has a rabbit board, and each bird has two blue, red, round, triangular and square boards.
Activity process
First, review the known figures (triangle, circle, square)
Guidance part: stimulate children's strong interest in activities.
(1) finger game: Little monkey builds a new house.
The little monkey built a new house, and the dog and kitten came to help, hammering nails and resisting shoulders. The house is beautifully built. When I opened the door, I forgot to leave a window. Square windows, circular windows and triangular windows.
(2) Teacher-child interaction
Teacher: The game is over. I want to ask the children, what shapes are the windows of the new house built by the little monkey in the game? (triangle, circle, square)
Second, show the PPT of the story "Graphic Baby Looking for Home" and get a preliminary understanding of the secondary classification of graphics.
(1) Play the first PPT (learn to use color coding to find a home)
Teacher: Today, Miss Gao brought a nice story to the children. The name of the story is "Graphic Baby Looking for Home" (see PPT). In the story, the little rabbit will encounter a difficult thing. (Little Rabbit skips to find a home, but he is too anxious to get in. It turned out that his door was locked by a problem and he couldn't get in. He wants the help of clever children. The question is: 66. 2. What color are they? How did they find their home? ) Children who need our cleverness, come and help! What is the hard part? Please read and listen carefully first. (PPT only plays until you find your home by color. )
There are triangular, square and round babies in the story. They are red and yellow. They are marked according to the color of the house: red and yellow.
(2) Play the second paragraph of PPT (learn to find a home with the same color and shape)
Teacher: Oh, the children are great. They all got it right. The problem lock has been opened. Rabbit is happy to give you applause. At this moment, Little Rabbit walked into his home happily. Look, (playing the second PPT) it's getting dark ... read the full text.
Teacher, the story is over again. Miss Gao has a problem and wants to ask the children for help! I asked the clever children to tell me how they found their own home to sleep. (According to the shape label) Let's see if this is the case. (Plays PPT) You guys are great. I'll give you a thumb to praise you!
Attachment: The story "Find Home with Pictures"
1, the first story
On a beautiful grassland, there are many graphic babies. One day, the sun came out and the weather was warm. On this day, Baby Round, Baby Triangle and Baby Fang all ran out in their favorite red and yellow clothes, and their good friend Bunny also ran over. They sang and danced together on the grass and had a good time!
Suddenly it rained heavily, and the babies were anxious to go home, but they didn't know where their home was. Little Nutbrown hare said don't worry, don't worry, I'll take you to your home. Come with me quickly. Look, there are two big houses here. One is the red house, the home of the red baby, and the other is the yellow house, the home of the yellow baby. At this time, the red circle, the red triangle and the red square returned to the red room, and the yellow circle, the yellow triangle and the yellow square also returned to the Huang family. Little rabbit skipped home, too.
2. The second story
It's getting dark and the rain has stopped. Mother moon came out with a little star. At this time, the graphic babies will go back to their homes to sleep, but which one is their home? Oh, it turns out that the door and shape of the graphic baby's house are the same, and the clothes they wear are the same color. I want the children to guess whose home this is. (The teacher points to the red round door and asks questions) In turn ... (The teacher plays PPT)
In this way, the graphic babies soon found their own homes, lived in their own rooms, and fell into a sweet dream. ...
Teacher: After the story is finished, Miss Gao has a question. I want to ask smart children to tell me how they find their own home to sleep in the dark. (According to the shape label) Then let's see if it is? (Play PPT) Correct answer, give you a thumb!
Teacher: The last question, please think it over. How did the graphic baby in the story find home for the first time? How did you find your home the second time? Ask questions again to deepen children's understanding of the home discovered by the colors and shapes of the graphics. )
Third, the teacher showed the second-level classification board and studied the second-level classification in depth.
1, importing
Teacher: Oh, all the children know that they found their home according to color marks and shape marks. Hey, listen, what's that noise? (The teaching assistant cries) Who is crying? It's the rabbit crying. It turned out that Tutu's good friend, Graphic Baby, attended Happy Camp. They came to the yellow field. The teacher scattered the graphic babies on the yellow table. After the activity, they want to go home, but they can't find their own home? Ask the child for help?
2. Learn the secondary classification
(1) Classification for the first time (only color marks are displayed)
Teacher: Let's see whose home this is. Whose home is this? (Red Home, Green Home)
Teacher: Oh, who will help this little rabbit and send its good friend Graphic Baby home? (Please ask some children to come and operate)
Teacher: Oh, the children are great. They were all sent home. How many graphic babies live in their home? If I have another one, can I stay? Oh, not too crowded. So when we send him home, we should arrange them one by one.
(2) The second classification (only the first page of the shape mark is displayed)
Teacher: Hey, where are you crying? There are some graphic babies behind the blackboard. They are also anxious to go home. Let's invite them to the blackboard and ask the children to help! So, where are these graphic babies' homes? Let's look at so many rooms here. Which one is theirs? Who will guess? Who wants to take them home? (Ask individual children to come and help)
Teacher: Wow, the children sent the graphic baby home. At this time, the graphic babies who came back to the color label house and the shape label house were very happy, and the bunny smiled happily. (Showing the whole secondary sorting board) Let's take a look at the home they sent with color code for the first time and the home they sent with shape code for the second time. This is called the secondary sorting board. What's your name? Secondary classification committee.
Fourth, children's operation and verification
1. Operation (PPT of operation sheet is displayed, and it is clearly required)
I found that the children in our class are really smart and capable, but Miss Gao still has a big problem here. I want to ask the children to help Miss Gao. The teacher's good friend, Baby Graphic, can't find a home either. One is playing at Bunny's house, and the other is playing at Bear's house. They can't find their home. Please send the graphic baby played by Bunny home to Color Label home, and the graphic baby played by Bear home to Color Label home. Please go back to your seat and send them home with cotton swabs and glue.
Step 2 confirm
Teacher: Miss Gao also made a copy here. (Showing PPT) Please have a look. Is it the same as mine?
Verb (abbreviation of verb) teacher's summary
Teacher: The children in our class are all great. They all helped Miss Gao send the graphic baby home. Now the surgical sheets, glue and cotton swabs on our desk are going home. Please take them home. (Play light music and let the children tidy up and put it in the middle of the table)
Reflection after class: In the previous teaching plan, the secondary classification of graphics has been arranged in large classes. This year will undoubtedly bring some difficulties to our middle-class children. So I thought: Is there a way for children to learn this kind of teaching knowledge and feel very relaxed and happy? For this teaching, there are mainly the following considerations:
1, teachers and students
In this teaching, the cooperation between teachers and children is quite tacit. First of all, I didn't put on the "teacher" hat for myself. At the beginning of the course, I used a teaching-related game "Little Monkey Building a New House" to "befriend", which made the children start to put aside the curiosity and nervousness brought by the teacher. Then I use PPT animation "Graphics Finding Home" to attract children, and children can initially understand how to find a home for graphics according to the interesting PPT story. Children are more interested.
2. Gains and losses
This teaching, can grasp the children's attention and interest is my biggest gain. There is still something in teaching that makes me think deeply. At the same time, there seems to be an invisible rope. One end of the rope is pulled by the teacher, and the other end of the rope is the road that the child completes the teacher's design step by step. The concept of children's education holds that "the value orientation of early childhood education no longer focuses on the transmission of static knowledge, but on children's emotional attitude and children's ability to explore and solve problems." What a teacher should do is to guide beside, not lead the way in front. When playing PPT, I only told the story once, but I didn't enter the next link, which made the children a little overwhelmed and didn't give them much room to think, so that some children were at a loss in the second link, so this place was my fault. In my classroom, the dominant position of teachers is obvious, and really highlighting the leading role of students is something I need to strengthen and pay attention to in future teaching. Therefore, if children change the secondary classification board, or not limited to red and green colors and only three shapes, or change the size of the graphic baby, let the children observe, think and complete by themselves, and at the same time the teacher gives some reminders and inspirations, then the children will consolidate and deepen this part of knowledge.

Teaching plan for large class mathematics activities: graphic finding home 3 design intention;
Children often come into contact with all kinds of graphics in their lives and ask what graphics they are. Paying attention to children's interests and lifelong education are two characteristics of my activities. Kindergarten is one of the most familiar environments for modern children to live and study. At the beginning of the activity, I asked the children to observe my wall chart. There are different graphics in different colors on the wall chart. Pictures composed of different graphics are to improve children's perception and understand the characteristics of various graphics. In the activity, the teacher appears as a guide, corrects the unclear or difficult places of children, and gives patient guidance, so that each child can fully and independently participate in the activity.
Activity objectives:
1. According to the characteristics of graphs, we can find out the proper positions of various graphs in the graph.
2. Can boldly and correctly express the characteristics and orientation of geometric figures.
3. Stimulate children's interest in learning graphics.
4. Guide children to actively interact with materials and experience the fun of mathematics activities.
5. Develop children's logical thinking ability.
Activity preparation:
One set of large-scale surgical materials for each person.
Activity flow:
1. (The teacher shows various shapes of graphics) Children, the king of the graphics kingdom brought gifts to our children today. Let's have a look. What's the difference between them? (Guide children to use two words, such as red triangle. )
2. The game "Graphic Classification". Let the children put the same pictures together. How do you divide your communication with your peers?
(1) Now these graphic babies all want to go home. Let's help them find a home together!
(2) (Show pictures) This is their home. Observe the table and understand the meaning of horizontal and vertical marks. Question: What is the first line of the table? What do you mean? What's the mark on the left? What do you mean?
(3) The teacher demonstrates putting the red circle into the corresponding grid. Put it aside and say: the red circle is in the second position on the left in the penultimate row.
(4) Ask individual children to try to choose some graphics, locate them according to two characteristics, and talk about the specific location.
3. Children use operating materials to classify graphics.
(1) provides a set of operation data for everyone. First carefully observe the graphics inside, and then determine which home the graphic baby should be placed in.
(2) Teachers give guidance.
4. Organize communication and talk about features and locations.
Question: What colors and graphics are the first few lines?
Activity reflection:
In this activity, children know the characteristics of colors and graphics. According to the characteristics of graphics, we can find out the appropriate positions of various graphics in the diagram. Through lively dialogues, games and other situations in the classroom, children's interest in learning can be improved and their desire to explore new knowledge can be generated. On the basis of understanding, children can provide learning materials for children to operate, experience and explore the production process of activities according to the characteristics of color and shape. Let children learn while playing, let children learn easily and happily, and fully display their enthusiasm and subjectivity, so that children can truly become the masters of learning. At the same time, in classroom teaching, we should pay attention to protecting children's opinions, developing children's creativity and encouraging children to be good at discovering unusual phenomena. However, in this class, my speech speed is a little fast and my language is not concise enough. During the demonstration, some children didn't hear the teacher's request clearly because they spoke too fast, which led to a problem being said. Many children below don't know what I'm asking. Moreover, my adaptability needs to be strengthened. This teaching and research activity made me understand that only through continuous serious and in-depth reflection can we find or approach an effective and perfect teaching method.
