Understand the activity objectives of classroom teaching plan 1 in neighboring middle schools;
1, initially understand the meaning of adjacent numbers within 5, and perceive the relationship between more 1 and less 1.
2. It can express the adjacent number of numbers within 5 to improve children's thinking ability.
Activity preparation:
Colored beads, digital puzzles, digital chest ornaments 1-5, cards for small houses, 5 for each person.
Activity flow:
1, take the line, the teacher plays the piano and let the children follow the music.
2. Online game: "Good Friends Hug"
In the first round, the teacher asked six children to clap their hands and read nursery rhymes: one, two, three, two people hug. (Find a good friend to hug next to) Repeat twice. In the second round, teachers can invite 9 or 12 people to play together, clap their hands and read children's songs: one, two, three, three hugs. (Find three people to hold together) Repeat twice.
3. Go back to your seat.
(1) The teacher shows the flower-shaped digital brooch 1-5 to let the children know.
(2) game: flowers open the door.
Game flow: The teacher first asks three children to play a game, and gives them three digital brooches 1-3 in turn, standing in a row. The teacher said 1 Xiaohua opened the door, and the child with the digital badge 1 made the action of opening the door and took a step forward. The teacher asked the children again, "What is the number of the little flower next to Xiaohua/kloc-0?" The child replied: "No.2, they are the closest." The teacher told the children that 1 and 2 are two adjacent numbers. Similarly, please ask No.3 Xiaohua, No.3 Xiaohua will open the door and take a step forward. Guide the children to say that 2 and 3 are adjacent numbers. (that is, the nearest two numbers are adjacent numbers, and there are two adjacent numbers to guide children to say 2, 1 and 3).
(3) Teachers show colored beads for children to observe, and then answer the corresponding question: "1 How much more than 2? (2 ratio 1 big) How much is 2 smaller than 3? (2 is 1 less than 3) 2 How many good friends do you have? (2 have two good friends) What is it? (1 and 3).
(4) Teacher's summary: Like this, every number above 1 has two good friends, one is less 1 and the other is more 1. (that is, these two numbers are the two closest numbers to it, that is, its neighbors. )
(5) The teacher tells a story and asks the children to put the house number on grandma cat's house. First, the teacher gave the children digital puzzles and cards of small houses, and asked them to take out the cards and digital puzzles of small houses from small bags. Then they put the bags behind the small chairs, put the digital cards on the small houses in sequence, and put a house number on each house. After the operation is completed, let the children observe and the teacher ask questions, and guide the children to say the adjacent numbers of 1, 2, 3, 4 and 5 respectively.
4. Exchange summary and organize school tools.
5. The game "Find Friends".
Teachers can divide the class into five groups to play games, and bring digital brooches for children to remember numbers. At the beginning of the game, the teacher can say a number at will. If the teacher says "4", please ask the child with the number badge 4 to pull two children who are more than 4 1 and less than 4 1 to stand out together (that is, list two adjacent numbers of 4), see who is the fastest and most accurate, give praise or reward, and report their two adjacent numbers (5 or 3) respectively. Finally, suppose that the neighboring numbers of 4 are 3 and 5. The game can be played repeatedly.
Effect analysis and reflection:
The activity was quite successful. Most children perform well in classroom routine, can understand the meaning of adjacent numbers, perceive the relationship between greater than 1 less than 1, and can quickly answer adjacent numbers within 5. However, after feedback from parents, some children's classroom routines are not ideal, and they have not fully achieved the objectives of this activity. This is also a detail that I neglected in this activity, so I will pay special attention to these details in the next activity to make the objectives of the activity more clear. In every teaching activity in the future, I will take good care of all the children and satisfy my parents.
Know the activity objectives of teaching plan 2 in adjacent middle schools;
1, perceive the adjacent relationship between two numbers before and after 2 and 3, and explore the fun of discovery.
2. Cultivate children's comparative judgment ability.
3. Develop visual perception and judgment.
4. Guide children to actively interact with materials and experience the fun of mathematics activities.
5. Develop children's logical thinking ability.
Activity preparation:
Provide three bottle caps with different colors, each with a set of 1-4 digital cards.
Activity flow:
1. Take three bottle caps of three different colors and arrange them in three horizontal rows one by one. The bottle caps in the middle row don't move, so that the three rows of bottle caps become more than one row. Discuss how to do this.
2. Find the corresponding number plate and stick it on the left side of the bottle cap. Discussion: What is the number of 1 less than 3, and where should it be ranked? What is 1 greater than 3, and where should it be ranked?
3. Guide the children to summarize: 3 There are two close friends, one is 2 1 smaller than 3, which ranks in front of 3, and the other is 4 1 larger than 3, which ranks behind 3.
4. Organize children to discuss who is their best friend. According to the previous methods and experience, guide children to verify with the help of bottle caps and digital cards.
5. Play the game of finding friends: The children are divided into five groups and arranged in three rows. The teacher said yes to 4, and the children were immediately arranged in rows 2, 3 and 4, and the people in the middle row did not move. See which group of children line up quickly and accurately. This group is the winner.
Activity expansion:
Put digital cards in the range of 1 to 10 and several bottle caps with different colors in the science area, so that children can further explore the adjacent numbers of numbers in 10.
