The activity design background of junior high school mathematics teaching plan "ordinal number1-5"1
Middle-class children do not have enough knowledge of numbers during their development. By learning ordinal numbers, children can further understand numbers, which is beneficial to their future study activities. Through games and intuitive observation activities, children's interest in learning can be stimulated, and children's learning habits of hands and brains can also be exercised to learn independently.
moving target

Followed by two ideas.
6. Serial numbers: an elephant and a braille card are represented by the number 1.
Two elephants and two Braille cards are represented by the number 2.
Seven, 1, friends row by themselves, (from less to more rows, teachers guide, one teaching aid for each person).
2. Compared with the teacher, did you do it right?
Eight, the teacher draws a picture, let the children observe it, and everyone corrects it together.
Nine, the teacher issued teaching AIDS, let the children do their own homework exercises, and the teacher toured the guidance.
Teaching reflection
The goal of this class is very clear, and we feel that the goal is still in place. It is easy for children to learn, but I think it is very complicated to change teaching AIDS frequently in educational activities, which is not conducive to intuitive presentation and affects children's acceptance.
Middle class math teaching plan "ordinal number1-5" 2 goal:
1, know the ordinal number 1-5, and initially understand the meaning of ordinal number.
2. Preliminary perception of ordinal order.
3. Form a good sense of order.
Prepare:
1. Prepare teaching aid: "Animals and houses"; Digital cards, mobile cars and animal headdresses.
2. Prepare school tools: "animals and houses"; "digital card"
3. Page 28 of the Operation Manual
Process:
1 Preparation activities
How many floors are there in Linglong Tower?
2. Group activities
The story "Animals Move". In the big forest, the animals' new houses have been built, which is very beautiful. The teacher shows the house in Animals and Houses, on 1-5 floor in the morning. Please count the children. How many floors does the new house have? Let's mark the building with digital baby. How?
Please put the "digital card" 1-5 on the house in order and read it out: the first floor, the second floor, the third floor, the fourth floor and the fifth floor.
Which small animals are moving into their new homes? While demonstrating the ordinal number 1-5, the teacher inserted the corresponding animals into the corresponding floors.
The teacher randomly hid a picture of a small animal, and the children said, "How many floors is the small animal missing?"
Animal exercise: children put on their hoods, and when the teacher says the name of an animal, the children in the seat will report where the animal ranks. Through observation, children can see that the arrangement order of animals may change from different directions.
3 Children operate the learning tool Animals and Houses;
The teacher showed the results of a single child's operation. The child said what floor his little animal lived on.
Complete the activities on page 28 of the workbook.
5 communication summary
First, second, third, fourth, fifth ... (queuing for water and doing exercises) appear in our life and study? These are ordinal numbers, which will make our life and study more orderly.
The activity design of middle school students' math lesson plan 1-5;
Mathematics plays an important role in kindergarten curriculum. Math games can create the best scene for children's hands-on, hands-on, brains and multi-sensory participation in learning activities, stimulate children's interest in learning, mobilize children's physical and mental potential, save time and complete learning tasks efficiently, cultivate good study habits and academic quality, and make intellectual quality develop harmoniously. This lesson helps children know ordinal numbers and know their order.
Activity objectives:
1, know the ordinal number 1-5, and initially understand the meaning of ordinal number.
2. Preliminary perception of ordinal order.
3. Form a good sense of order.
Activity preparation:
1, slide ppt
2. Children's homework
Activity flow:
First, import the story.
Digital songs: 1 Write like a pencil, swim like a duckling in the water, listen like ears, float like a red flag in the wind, and buy food like a scale hook.
Second, collective activities.
The story "Animals Move". In the big forest, the animals' new houses have been built, but they are beautiful. Does the child want to see it? Then come and have a look with me! (showing the house)
1. What animal's home is this beautiful new house? Let's meet them! (showing small animals)
2. Does the child know which floor he lives on? Please tell the children which floor they live on.
Children, think about how we count the floors. Do you count from top to bottom or from bottom to top? The teacher leads the children to say that the floors are counted from bottom to top. )
Ask the children and teachers to help the animals count how many floors there are in their new house. Let's mark buildings with digital treasures in the digital kingdom. (Show the number 1-5 and stick it on the new house in order and let the children read it, first floor, second floor, third floor, fourth floor and fifth floor)
The small animals all moved into the new house, and they were very happy. They are going to invite our children to visit us. Then we need to know where each small animal lives. We can count it. What floor is it? What floor does the elephant live on? We can count, 1, the cat lives on the second floor, the pony lives on the third floor, the dog lives on the fourth floor and the rabbit lives on the fifth floor ... "
The teacher randomly hid two pictures of animals, a puppy and a kitten. Let the children say, "How many floors is xx animal missing?" .
Third, business activities
1. Show pictures of small animals. Please tell the children which floor these little animals live on. What floor do you live on? Let it find the digital baby.
There are some small animals here. They want the children to help them line up. They lined up from left to right. Who is the first one? We are going to find the digital baby 1 and hold hands with it. Who is the second one? We will find Digital Baby 2.
3. Let the children finish their homework by themselves.
Activity reflection:
This math activity, I carefully designed every link, every link is interlocking and progressive. At the beginning of the activity, in order to make the children concentrate, I brought them into the classroom with digital songs. I said mysteriously that children and animals have built a new house, which is very beautiful. I want to take the children to see their attention at once. Then let the children enter an interesting story. I use small animals (lions, kittens, puppies, chickens, rabbits) to move to a new home.
When designing and arranging classroom activities, I noticed several points: the game is novel, diverse and interesting, which can effectively stimulate children's internal drive and make them learn actively and happily. In order to let children know the ordinal number 1, 2, 3, 4 and 5. Let children master the story of building a new house and tell them that different animals live on different floors, which makes it easier for children to tell a small animal that it can only live on one floor. Thirdly, I play hide-and-seek games, such as: which floor of XX is missing? Let the children speak. The last link is the form of queuing small animals for children to operate. Deepen and consolidate the learned ordinal numbers 1, 2, 3, 4, 5.
The middle class mathematics teaching plan "ordinal number1-5" 4 teaching purpose:
1, a preliminary understanding of the meaning of ordinal numbers
2. Preliminary perception of ordinal sequence
3. Form a good sense of order.
Teaching preparation: teaching AIDS animals and houses (animals in the house), learning tools animals and houses.
Emphasis and difficulty in teaching: children can understand the meaning of ordinal numbers.
Teaching process:
1, online game "Lights" Yi Deng, shiny, two lights, bright, three lights, four lights, five lights, shining in the street, sit quietly, shout the Montessori slogan of our class "I am the best in Montessori today" and play the game of several tall buildings "on the first floor, the second floor, the third floor, the fourth floor, the fifth floor.
2. Situational teaching: The teacher found a beautiful house. Do you want to see it?
3. Enjoy and discuss together.
4. Situational teaching: Do you know who lives in it? The initial perceptual ordinal numbers are displayed respectively. They want to change houses. Will you help?
5. Children can operate freely to help small animals divide the house. The teacher asked the children's animal addresses and asked them to practice saying ordinal numbers.
6. Summary: Today, the children helped the small animals divide the house, go home and tell their parents which floor they live on, and then count how many floors your building has. What floor does your family live on?
7. put away your school tools
