Teaching plan for large class mathematics activities: increase 7 1 activity target;
1. According to the number of objects in the picture and the process of merging two cards, learn the addition formula of 7 to consolidate the understanding of the meaning of addition.
2. Cultivate judgment.
3. Cultivate children's ability to recognize numbers.
4. Let children understand simple mathematical principles.
5. Stimulate children's interest in learning.
Activity preparation:
1, a big tree, all kinds of magnetic teaching AIDS for small animals that can climb trees.
Some problems about the addition formula within 2 or 6. (Used by teachers when showing in train games)
3. Every child has a set of school tools.
4, a cloth bag, which contains a variety of additives within 7. (The topic should be made into various gifts)
Activity flow:
(a), "train" game comments increased by less than 6.
The teacher shows the addition questions within 6, and the children answer the numbers by train according to their seats.
(2) See how much it costs.
1, (showing the big tree) Today, many small animals come to our class to play. They are playing the game of climbing trees, and want the children to put out the results of climbing trees with formulas.
2. The teacher first took out five animals to the tree, then took out two small animals and asked a child to come up and put out the formula of 5+2 = 7. Please tell some children what each number in the formula means.
3. Please practice the same table: 3+4 = 7, 6+ 1 = 7, 2+5 = 7, 1+6 = 7, 4+3 = 7 and other arithmetic problems. (Pendulum with learning tools)
(3) Games (touching gifts) further consolidate the addition within 7.
The children are very capable, the animals are having a good time and want to give presents to the children. Let the children touch the gifts one by one, but they must answer the arithmetic questions behind the gifts to get the gifts.
Activity reflection:
Use standardized language to deepen their understanding of mathematical knowledge and make them understand the meaning of related concepts. Only by fully understanding mathematical theory, scientific and comprehensive understanding of mathematical concepts and children's thinking characteristics and learning rules can mathematical concepts be correctly applied to teaching activities. Only in this way can children be effectively guided to learn, understand and use mathematics in their lives.
Teaching plan for math activities in large classes: increase by 7.2 I. Activity objectives:
1. Review the decomposition and combination of 6 and 7, and add 6 and 7 on this basis.
2. Learn the addition of 6 and 7 to help children further understand the law of changing the position of two addends and perceive the quantitative relationship expressed by the addition formula.

Learning tools: digital card 1-7, "+""="; 2 shopping vouchers, 1 eraser, pencil, pencil sharpener, glue stick, notebook and pencil case. (small) Third, the activity process:
1. Dialogue import activity:
Teachers interact with existing objects in the classroom. For example, the teacher took out three books first and asked the children how many. Then he took out four books and asked the children how many * * *? Count and say the total.
2. The teacher takes out teaching AIDS, shopping vouchers, erasers, pencils, pencil sharpeners, glue sticks, notebooks and pencil boxes, and asks the children to take out corresponding learning tools.
3. The teacher let the children know the price on the shopping voucher, first look at the price of each commodity, and then ask the children: "What two things can I buy with the shopping voucher of 6 yuan money?" Please let the children speak freely. The teacher divided the children into two groups. What did a man buy with 6 yuan? The other party holds the goods and then makes creative shopping. Finally, ask each group of children to answer what they bought with 6 yuan money.
Third, the teacher summed it up.
4. In the same way, let children buy things with 7 yuan money coupons, and the rules of the game are the same as above.
5. Listen and answer: According to the number of times the teacher clapped his hands, the children give the corresponding digital cards on the blackboard. Then, the children put the plus sign and the equal sign on it, and let other children say the answers, and put the corresponding numbers on the number board. Let the children take turns playing games.
6. Children complete the "mysterious garden" in the classroom activity book: the teacher guides the children to classify according to the characteristics of color, size and shape, and then calculates the formula according to the classification and adds it up.
Four. Extension of activities:
In a regional sunshine supermarket in the class, the teacher used school vouchers and priced goods to make the children think. There are several ways to buy three or four items with 7 yuan coupons.
Activity reflection:
Only by fully understanding mathematical theory, scientific and comprehensive understanding of mathematical concepts and children's thinking characteristics and learning rules can mathematical concepts be correctly applied to teaching activities. Only in this way can children be effectively guided to learn, understand and use mathematics in their lives.
Teaching plan for mathematics activities in large classes: adding 7 3. Teaching objectives

Teacher: Today, the dog invited the lamb to his house, and the monkey invited the lamb to his house. What should the lamb do? Show 7 lambs, and children can freely explore and discuss how to divide the lambs into two parts. The teacher asked the children to list 7 points on the blackboard.
(2) In the basic part, learn the addition of 7.
1, learn the addition of 7, and list the addition formulas according to the pictures.
(1), show the picture, and the teacher tells the application question according to the picture: 1 A butterfly flies in the garden, and six butterflies fly in. How many butterflies are there in the garden? Guide children to learn the addition problem 1+6=7, and list another problem 6+ 1=7 according to the exchange law, and ask individual children to demonstrate on stage.
(2) The teacher tells the application problem according to the picture and guides the children to learn the addition problem 2+5=7. According to the exchange law, list an addition problem 5+2=7, and then learn the addition problem 3+4=7 in turn. According to the exchange law, another addition problem 4+3=7 is listed. Please show it to some children.
(2), the game "Happy Math Camp", competition activities, review and consolidate addition 7.
1. Play games. The first floor is "I'll do the math". The men's team will sort out the application questions according to the pictures and the women's team will answer them. With snowflake as an auxiliary calculation, hold up the correct digital card and exchange it.
2. The second level, try to answer the question "Look at your figure". After the two passes, see which team has more marks, choose the winning team and distribute prizes.
(3) Review the game "Go for an outing" by 7.
1. The teacher introduces the name of the game, how to play it and matters needing attention.
2. The teacher showed the formulas one by one, and the children worked out the numbers and quickly stood on the car with the corresponding numbers. The teacher praised the quick and accurate child.
3. The game will be over after playing several times.
Teaching plan for large class mathematics activities: addition 7, activity goal 4;
1, learn to apply the exchange law plus 7, and try to tell your own operation activities.
2. Feel the joy of communicating with peers to solve problems.
3. Cultivate children's comparative judgment ability.
4. Develop the agility and logic of children's thinking.
5. Stimulate children's interest in learning and experience the happiness of mathematics activities.
Activity preparation:
Composition decomposition of 1 and learned 7
2. PPT courseware, a record card, a pencil and an eraser, six pictures for finding formulas, several addition formulas within 7, two dice with formulas within 7, and self-made chessboard.
Activity flow:
1. Review the composition of 7 through the game of "touching the ball".
(In the introduction, I thought, "If you play a game of touching the ball with a time flying car, you can take your child to a mysterious place." Stimulate children's interest in participating in activities and review the composition of 7. )
2. Stimulate children's interest in the situation of "saving lazy sheep with wisdom" and guide children to learn by exchange.
(1) Guide the children to "find the secret in the balloon and find the way to Wolfsburg", learn to list the first set of formulas with pictures, and find the exchange rules in the addition formula.
Question: What's in the picture? What's the difference between balloons?
Yellow? How many red ones? How many balloons are there?
② Verification: What is your list? What do these numbers stand for? ( 1+6=7)
③ Summary: 1 yellow balloon and 6 red balloons add up to 7 balloons.
④ Question: What happened to the balloon? (The teacher showed the position exchange of 1 balloon and 6 balloons in the courseware. )
Who's in front? (Red) How much? Who is in the back (yellow) and how many people are there? How many balloons are there?
⑤ Verification: What is your list? (6+ 1=7) Are there any similarities and differences between the two formulas?
⑥ Summary: In addition, after the positions of the two addends before and after the plus sign are exchanged, the total number remains unchanged.
(This link is the focus and difficulty of the activity. Through the demonstration of courseware, children are guided to observe and understand the first set of formulas for the addition of 7, and the law of "the positions of the two addends before and after the plus sign are exchanged, and the total number remains unchanged" is found in the two formulas. )
(2) Guide children to "walk through flowers" in the same way, and list the second set of formulas according to their own knowledge and experience.
Question: What's in the picture? What's the difference between florets?
How many purple flowers are there? How many red flowers are there? How many flowers are there?
② Verification: What is your list? How else can we make it? (2+5=7、5+2=7)
Look at the flowers of different colors in the picture and list the formulas. If you finish the flowers, you can move them away.
(This link guides children to try to list formulas by exchange and understand the meaning of each number in the formula. )
(3) Guide children to "walk through the Woods", impart knowledge and experience, and list the third set of formulas.
Look at the small trees with different heights in the picture and list the formulas. If you go right, you can reach Wolf Castle.
(In this session, the teacher directly asked the children to observe the content of the picture by themselves without asking any questions, and listed two addition formulas. )
In the whole learning process, children are guided to actively participate in learning and master the addition of 7 by creating the situation that "you can reach the Wolf Castle to save sheep after three passes", from "listing formulas to discover the exchange law"-"trying to list the second set of formulas by exchange method"-"transferring the acquired knowledge and experience to list the third set of formulas".
3. "Get the password card to enter the Wolf Castle", communicate with teachers and peers to verify the operation results, and try to express your own operation process boldly.
(When children can actively express their operation process with teachers or companions, it is convenient to make a mark on the children's operation card, so that this operation card can become a password card for entering the Wolf Castle. )
(In this link, you need to communicate with teachers and peers to "get the password card" to enter the Wolf Castle to save the sheep, help children sort out the three groups of addition formulas of 7, and encourage children to boldly try to tell their own arithmetic activities. )
4. "Wolf Fort Save Sheep" group work, internalizing the mathematical experience of migration.
(1) Looking for lazy sheep (see figure, orally self-compiled application questions, parallel calculation): Children find the correct formula from some formulas according to the different characteristics of people, bees and fish in the picture, and write down the numbers. The correct formula can be reversed to spell the lazy sheep pattern to be verified.
(2) Coloring for Big Big Wolf: Six children, each with a picture, work out the number and color the part with the number 7; Put the six pictures together, and a complete image of Big Big Wolf will appear.
(3) Wolf Castle Escape: Two young children are playing chess. When the number of the formula on the dice is several, they walk a few steps on the chessboard to see who reaches the finish line first and escapes from the Wolf Castle.
Grouping operation (1)
Group operation (2)
Group operation (3)
Consolidate, deepen and internalize the key knowledge of this activity in the group operation of "Wolf Castle Saving Sheep". )
The celebration of "lazy sheep saved" is over.
Activity reflection:
This activity aroused children's interest in participating in the activity by creating a story situation of "saving lazy sheep with wisdom" in the cartoon Pleasant Goat and Big Big Wolf, which children are familiar with. At the same time, the progressive problem is designed, with vivid courseware, so that children can learn the addition of 7 happily in the game and find the law of using exchange.
First of all, according to the children's cognitive level, the actual situation and the characteristics of the textbook itself, I mainly divided the activities into four blocks for organization. Situation 7 Introduction of "Touching the Ball" Game-Addition-Communication Verification-Internalization Transfer of Grouping Operation and Perceptual Learning. In the introduction, I think, "If you play ball games with time flies, you can take your children to mysterious places." Stimulate children's interest in participating in activities and review the composition of 7. Next, the second part is the key and difficult part of the activity. Children should understand the meaning of addition, learn to look at pictures and formulas, and understand that the positions of the two addends remain unchanged before and after the plus sign exchange. In this link, I guide children to observe formulas through three levels, and let them gain more direct knowledge accumulation through hands-on operation, table recording and other forms. Letting children observe with tasks not only cultivates their interest in observation, satisfies their desire to express, but also enhances their understanding of the meaning of "addition". Then guide the children to express the exchange rules they found from the three groups of formulas, exchange with their peers and teachers, and take the affirmative words as the verification result of the password game entering the gate of Wolfsburg. Finally, the key knowledge of this activity will be consolidated, deepened and internalized in the group work of "Wolf Castle Saving Sheep". Children can actively participate in the whole activity, have a high interest, and their ideas have always followed the teacher. All the children can correctly list the addition formula of 7. After this activity, I found:
Advantages:
1, the situation created has greatly attracted children's interest in participating in activities, and children's routines have made obvious progress.
2. The level of each link in the activity is clear and can be progressive.
3. Make clear the requirements in time before letting the children operate, and let the children operate as required.
Children can achieve the expected effect in this activity.
Insufficient:
1. In the activity, because children are too eager to express and use the exchange rules, the problem of guiding children to discover the rules is not raised enough. Teachers should summarize first before children can express them.
2. In the third communication verification session, the teacher's guide language can be clearer, combined with wall charts and gestures.
3. The pictures of some pages in the courseware are more complicated, such as the flowers and trees are not prominent enough.
Through this activity, I have the following insights on organizing math activities in the future: first, teachers must observe children's life needs, enter children's lives, understand and understand children, see the world with children's eyes, and guide children to understand mathematics in life; Secondly, teachers should have comprehensive and scientific new values of mathematics education, make children's daily life mathematical and explore the active situational mathematics activity mode for children, which is an effective way to implement the spirit of the outline. Moreover, teachers must learn mathematical theory and understand mathematical concepts. Use standardized language to deepen their understanding of mathematical knowledge and make them understand the meaning of related concepts. Only by fully understanding mathematical theory, scientific and comprehensive understanding of mathematical concepts and children's thinking characteristics and learning rules can mathematical concepts be correctly applied to teaching activities. Only in this way can children be effectively guided to learn, understand and use mathematics in their lives.
