Mathematics teaching plan for large classes: 7 1 decomposition of activity objectives;
1, children learn the decomposition and synthesis of 7 through cooperative communication, and perceive the order of the sum of numbers.
2. Let children learn and develop together in independent exploration, cooperation and exchange, and fully experience the happiness of group mutual assistance and cooperative learning.
2. Be able to cooperate with peers and try to record the results.
2. Improve the ability of logical reasoning and form a good habit of doing things in an orderly way.
Activity preparation:
1, pictures of watermelons and peaches of different sizes, colors and shapes, different kinds of mosaic toys and waste materials.
2. Music tape: "Where are my friends?"
3. Cards with numbers of 1-6 in different colors or patterns.
4, 7 typing record table.
Activity flow:
First, the creation of situations
1, clap your hands game: the teacher reviews the composition of 6 with the children by asking and answering questions.
Teacher: Hey, how many balls did my 1 ball touch?
Child: Hey, your 1 ball touched five balls.
2. Each group leader reports by himself, and the teacher puts corresponding stickers on each group.
3. Teacher: Every child in our sheep team is excellent. Today, the teacher specially invited a friend (show the number 7) for you, and let the number 7 be the referee to judge which sheep team won the final victory.
Second, the sheep sheep war
1, Judge No.7 prepared 7 items for each of our children. (Showing watermelons, peaches, mosaic toys and some waste), but the number 7 can give you requirements:
(1) Please don't move after each group gets seven items. Observe the similarities and differences of these items first, then divide these items into two parts and tell me what is the basis of your division. Turn your head to see which group has more methods.
(2) Fill in your scoring results on the scoring record.
2. Children are recorded in groups, and teachers patrol and give individual guidance.
Pleasant Goat Team Material: Peach Blossom Map; American sheep team material: watermelon map; Boiling sheep team material: goldfish pictures; Lazy sheep team material: mosaic toys; Jonie team materials: milk boxes and bottles; Slow sheep team materials: all kinds of cartons (toothpaste boxes, medicine boxes, cigarette cases). etc
3. Children report to Meiyangyang Team: Teacher, our group divides 7 into 1 and 6 according to the size of watermelon.
Pleasant Goat Team: Our team divides 7 into 2 and 5 according to the types of peaches.
Team Jonie: The materials in our group are all about milk drinks. 7 is divided into 3 and 4 according to boxes and bottles;
4. The teacher summed it up.
How many decomposition methods can guide children to summarize 7?
Judges No.5 and No.7 awarded winning prizes and encouraged them.
Game: Where is my friend? 1. The teacher gives each child a digital card.
2. Find friends.
Music "Where are my friends?" Children are singing and looking for their good friends with digital cards in their hands.
Children check each other and find suitable friends.
4. Report.
I am Strawberry 3, I am Strawberry 4, and together we are the number 7. We are good friends. (Two good friends hug each other)
Fourthly, we have studied the decomposition of numbers 2-7, and we also know that there are many methods of decomposition. Ask the children to go home and explore how many decomposition methods there are and what rules you can find.
Activity reflection:
Activity reflection can be thought from the following aspects, and it is not necessary to cover everything:
1, reflect on the cognitive changes of activity content, teaching theory and children's learning style in the process of preparing lessons.
2. Reflection on the activity process: (Whether the following aspects are true or not, analyze the reasons for yes or no, so as to sum up experience or propose improvement measures)
(1) Reflection on children's development, such as whether they are understood, respected and accepted? Is there an appropriate amount of free space? Can you develop independently in emotion, attitude, ability, knowledge and skills through interaction with environmental materials, peers and teachers?
(2) Reflection on teachers' professional development, for example, do you know children's experience level, learning characteristics and personality characteristics? Can we grasp the core value of educational content and its development clues? Can you use your least support to promote your child's maximum development?
(3) Reflection on teacher-child interaction, such as teacher-child cooperation, whether teachers can adjust teaching according to children's needs.
3. Comment on the effect of the activity. Find your own strengths and weaknesses in the verification and analysis of goals and strategies, and make clear the direction of future improvement and perfection.
4. If you were given this course again, how would you take it? Any new ideas? Or how did the teachers or experts who attended the class at that time evaluate your class? What does it inspire you?
Mathematics teaching plan for large class: 7 decomposition 2 activity design background
The synthesis and decomposition of numbers is an important part of digital concept education. The new "Outline" requires children to "perceive the quantitative relationship of things from life and games", and also pays attention to children's ability to explore, operate, communicate, solve problems and cooperate. This semester, the children in the big class have learned the decomposition and composition of numbers within 2-6, and the children have had some experience in the composition of numbers. I try to let the children do it by themselves, then record the results, find the law of decomposition and composition under the guidance of the teacher, let the children play middle school, and achieve the combination of activity goals and children's interest optimization.
moving target
1, children feel the decomposition of 7 through independent exploration and hands-on operation, and master the six points of 7.
2. On the basis of the decomposition and composition of perceived numbers, master the laws of number increase and decrease and mutual exchange.
3. Develop children's ability to observe, analyze and record, and cultivate children's interest in mathematics.
4. Cultivate children's comparative judgment ability.
5. Develop children's logical thinking ability.
Teaching emphases and difficulties
1. Perceive the relationship between the whole and the part, learn and record the six points of 7.
2. Summarize the law of decomposition and synthesis of numbers within 7.
Activities to be prepared
Teaching AIDS: a large wall chart (two houses on the picture, the decomposition of 7 with a space on each side of the picture), 7 cards, markers and recording paper.
Learning tools: each child has a picture (there are two houses on the picture, and there is a space on each side of the picture with a score of 6), and 7 small batches of apple cards, pencils, erasers and 1-6 digital cards.
Activity process
(1) import
1, Teacher: Autumn is coming and the fruit on the tree is ripe. Mother Tree wants to give apples to two little monkeys. Show me the wall chart, the apple tree and seven apples.
Q: Mother Tree wants to give it to the little monkey. How to share?
2. Show the big wall chart, which leads to the "decomposition of 7"
Teacher: Distribute the apples to the little monkey's house, and each apple (counting seven apples with the children) will have a "7" digital card.
Teacher: How do you divide these seven apples? Mother Tree is worried. I don't know how to divide it. How many kinds of apples are there? Please tell the children.
(2) Basic part
1. The children divided seven small apples into two rooms and recorded the distribution results of each room.
2。 Please come to the front and talk about your integral results. The teacher recorded the children's division of labor on the record paper.
3. The teacher summed up the children's points and summed up the six points of "7".
4. Observe children's disorderly division and guide learning to decompose "7" in an orderly way.
(1) The teacher showed the division of seven apples and counted the number of apples in two houses with the children. Source lesson plan network) and record the results. "7" can be divided into 1 and 6,2 and 5,3 and 4,4 and 3,5 and 2. 6 and 1
(2) Children observe the decomposition formula of "7", initially grasp the orderly decomposition composition of "7", and understand the law of number increase and decrease and exchange.
5. The child divided the house for the small animal for the second time, tried to break down the "7" in an orderly way, and recorded the results of each division.
(3), the end part
The game "find friends"
Each child chooses a digital card (1-6) to wear, and together with the music of finding friends, find the child with the number "7".
Teaching reflection
According to the spirit of the new syllabus, the design of this activity requires children to "perceive the quantitative relationship of things from life and games", and also pays attention to children's ability to explore, operate, communicate, solve problems and cooperate. The synthesis and decomposition of numbers is an important part of digital concept education. This semester, the children in our big class have learned the decomposition and composition of numbers within 2-6, and the children have had some experience in the composition of numbers. I try to let the children do it by themselves, then record the results, find the law of decomposition and composition under the guidance of the teacher, let the children play middle school, and achieve the combination of activity goals and children's interest optimization. In this activity, children try to share apples. Through independent exploration and hands-on operation, they perceive the decomposition composition of 7, master the six divisions of 7, and master the law of number increase and decrease and exchange composition on the basis of perceiving the decomposition composition of numbers.
The activity revolves around giving apples to small animals. In addition, children are willing to help small animals divide houses, which fully mobilizes the enthusiasm of children to operate and explore independently. In the process of distributing apples for the first time and recording them, the children found six ways to divide "7" through calculation and exploration. When showing the allocation records of children's rooms, some children did not find out six ways to divide "7", and some divided figures added up to less than "7". This is the first time a child has tried recording. I will pay more attention to those who have not mastered it in the next link. Next, guide and observe the disorderly division of children. The teacher demonstrates the division of apples, counts the number of apples with the children while dividing, and records the results of the division. "7" can be divided into 1 and 6, 2 and 5, 3 and 4, 4 and 3, 5 and 2, 6 and 1, which leads to the orderly decomposition of learning to form "7". Children obey "7". When children divide apples for the second time, they should master the orderly decomposition of "7" and record the division results of each room. The activity ended in the cheerful atmosphere of "Find Friends" game, and the children realized the combination of activity goals and children's interest optimization through exploration, operation, communication, playing and learning.

Activity process
1. Listening to music and learning tools
2. The game "Drumming"
3. Learn seven decomposition components through stories to understand the complementary relationship between each part.
(1) Learn the decomposition of 7 in the story form of Apple Ripe.
Show me seven green ones.
Story: There is a second kindergarten in meihekou city, Jilin Province. There is an apple tree in the kindergarten yard. In autumn, there are seven apples on the tree. The first day. 1 Apple ripens and turns red.
The teacher turned a green chess piece into a red chess piece and showed the record sheet.
Question 7 is divided into 1 and what? What is the sum of 1 and 6?
Please use the "camera" to photograph the apple ripening process on the first day.
The next day, 1 apple ripened and turned red (as above).
(2) Guide children to further understand the complementary relationship of "one part increases 1, the other part decreases 1, and the total number remains unchanged".
The teacher demonstrated and compared the number of red apples on 1 day and the second day.
Question: 1 How many red and green apples were there on the tree that day? How red and green are they the next day? Red (one more) green? (One is missing)
Why is there more red and less green? Because there are only seven apples on the tree, the more red, the less green. )
(3) Show the differences of 7 through the story.
Let the children tell stories and put chess pieces. When the story is over, let's say one kind of separation and combination, and then let go of another.
(4) Guide children to further understand the complementary relationship between the number of parts (increasing one by one, decreasing one by one)
