Activity process:
First, lead to the topic and stimulate interest
Teacher: "Little monkeys, grandma monkey called and said that the peaches in the yard were ripe. Are you happy to ask our little monkeys to pick peaches?" (happy) ok! Then let's go! Grandma's house is far from us, so we should be brave! Not afraid of difficulties. "
Second, the little monkey went to pick peaches.
1 Crossing the stream:
(1) "mother monkey" (teacher) took "little monkey" (children) to pick peaches, but there was a stream blocking the way. There were many stones, big and small. There is also a sign by the stream (please step on the stones, only the stones with the calculated number of 10, and you will fall into the water if you step on the wrong one).
(2) Teacher: "Hurry up and find the stone you can step on. Which stone can you step on?" Why? How did you work it out? "
(3) Children make corresponding calculations: 4+6, 3+7, 8+2, etc., and tell the operation process.
(4) After finding out, children cross the stream one by one.
2 Rent a basket:
(1) finally crossed the stream safely, and the little monkeys walked on, huh? There is also a rental house by the roadside, which specializes in renting baskets. It's nice. Just in time to lend us the basket. There is also a sign outside the rental house (only the basket 10 is for rent, please look at the three numbers clearly, and add up to 10, and this basket will be rented to you).
(2) Teacher: "Little monkeys quickly find out which baskets are 10, and tell me how you worked them out? Why do you want to use this method to calculate? " (fast and accurate)
(3) Children perform corresponding operations: 3+3+4, 2+3+5, 1+4+5, etc.
Third, the little monkey picks peaches:
Teachers and students: Wow! There are so many big and red peaches!
The little monkey is ready to pick peaches.
(1) The teacher explained the requirements: some peaches have formulas, and some peaches have numbers (4, 6, or 2, 3, 5).
(2) Pick only peaches with the sum of 10.
Fourth, celebrate the harvest:
(1) The teacher played cheerful music, and the little monkeys shared the harvest and joy of their labor with joy.
(2) The teacher plays relaxed music, and the monkeys stabilize their emotions and rest and eat "peaches".
Fifth, after-school extension: the game "selling peaches".

Teaching plan 4 of "Addition within 10", a math activity in large classes, aims at:
Add and subtract within 1 and review 10, and the operation can be performed accurately and quickly.
2. Let children experience the fun brought by mathematical activities in the game and cultivate a good game order for children.
Prepare:
Kitten home, stream, environment layout; Crocodile headdress, please play with the class teacher.
Process:
First, to catch fish and stimulate children's desire.
1, children, Teacher Lin wants to take you to catch fish today. Do you want to go?
2. Before I go, I want to test the children in Class 7, and only those who pass the test are qualified to catch fish!
3. Let's start with a bumper ball. Do you know what a bumper ball is?
Explanation: For example, if you touch 10 ball, it means that Mr. Lin's ball and your's ball add up to 10 ball, understand?
4, good! Now please catch the ball. Please five or six children.
Second, catch fish.
1, explanation of catching fish:
How nice! Now we can prepare to catch fish, but there are not only fish in this pond, but also a crocodile who is hungry. We children should be careful when catching fish. When you see the crocodile coming, you should jump on a big stone with the number 10 at once. So you can avoid crocodiles. If the count is not 10 or you don't jump on the stone, then you will be the crocodile's breakfast. Everyone catches a fish at a time. Do you remember?
2. Catch fish in three batches.
The first time: summarize those who were caught: those who fled to other places.
The second time: encourage those who are caught and sum up experience.
The third time: praise successful children.
Third, sell fish.
1, children who catch fish sit in batches according to the color of the fish.
2. Explain the meaning of numbers on fish.
3. Rules for buying fish: Buy two fish at a time, one is red and the other is blue, and the total is 10 yuan.
IV. Extension activities:
Throw fish and money into the corner of the district, so that children can continue to operate in future activities.
Lesson 5 of the math activity "Addition within 10" for large classes Review content: `Addition within 20 and subtraction within 10.
Review requirements: through calculation, students can deepen the meaning of addition and subtraction, and improve their proficiency in carrying addition within 20.
Review key points: carry addition within 0
Teaching process:
First, basic exercises
math play
1, the teacher will1-10 two groups of cards, out of order, and put them in two cartons.
2. One student draws out two cards and tells the number quickly. If the calculation is correct, he will leave the card in his own hand. If the calculation is wrong, he will put the card back. Then another student draws cards and calculates the number. This will take turns until all the cards are drawn. Finally, the winner will be the one who gets more cards in his hand.
Second, guide the exercise
1, Question 6 Review carry addition within 20.
(1) Divide the students into groups of three. One student will show the card of oral arithmetic and judge it. The other two students will answer first to see who is right and fast. Then, the three students will exchange roles and play again.
(2) depending on the calculation (driving a train)
(3) Math games, reviewing the addition of one digit through games. Teachers can draw two cards from 20 cards by name, and quickly say the sum of the two numbers. The way is: a student draws out two cards and tells the number quickly. If the calculation is correct, leave the card in his own hand. If the calculation is wrong, put the card back. Then another student draws cards and still counts. So take turns to draw until all the cards are drawn and counted. Finally, the more cards you get, the better.
(4) Review the game of addition within 20 minutes. Teachers can divide students into two groups. Students in one group say a formula, students in the other group say the number, and then the two groups exchange. Students who say the array say the formula and students in the formula group say the number. Say the same number of formulas, which group answers more correctly and which group wins. Each student can also take a set of cards with the numbers1~ 20 written on them, and often play math games of addition and subtraction in and out of class. The game is played by a group of three people, one is the referee, and the other two play cards to answer first. When you encounter two single digits, add them first, then subtract the decimal from the large number, and the referee will evaluate, score and summarize the outcome. Three people take turns to be referees.
2. Review the subtraction within 10.
(1) Review the subtraction of numbers in 10 as a game. The teacher can ask several students to each take a digital card, and the teacher takes out a card (1~10), so that the students can subtract the number they take from the number taken by the teacher. Then the teacher will change another card, so that the students can reduce it again ... You can also change several students to do it, and see which group of students can do it right and quickly.
(2) depending on the calculation (driving a train)

Large class math activity "Addition within 10" Teaching plan 7 Activity objective:
1. Review addition and subtraction within 10.
2. Be able to take an active part in math activities and answer questions boldly.
3. Develop good operating habits and return the items to their original places after the operation is completed.
4. Let children experience the fun of math activities.
5. Develop children's logical thinking ability.
Activity preparation:
1, focal length preparation: 2 plastic baskets are used as "granary" and "grain bag" (the formula within 10 is written on it).
2. Preparation of learning tools: two-color discs 10 (red on the front and blue on the back), a number of formula cards, flying chess, soda lids, plastic bowls, playing cards, red dates, etc.
Activity process:
First, prepare for activities.
Game: Clap your hands and ask questions. Teachers ask questions 10, and children answer them. The teacher asked, "Let me ask you something, kid. How many can 10 be divided into?" The child replied: "Teacher X, tell you that 10 can be divided into 1 and 9, 2 and 8, 3 and 7 ... Second, game activities.
Create a game scene: a game series. The king of the game kingdom knows that all children like to play games, so the king sent messengers to send many games. Let's have enough fun together today.
1. Game "Two-color Card". There are 10 two-color cards (red on the front and blue on the back) thrown upward. After the two-color cards land, count how many red cards, how many blue cards, and how many red cards and blue cards are combined? The teacher listed the children's answers on the blackboard with formulas.
2. Game "Buckle Bowl" is a group of 5 people. Each group prepares 10 soda bottle caps and a plastic bowl. A child spreads the bottle caps on the table with his left hand and buckles some bottle caps with his right hand. Let's count the bottle caps left on the table and calculate how many bottle caps are buckled in the bowl together. You can adjust the total number of bottle caps to review the subtraction within 10.
3. The game "Scratch, Scratch, Scratch" will dig a hole in the shoebox and put 10 red dates in it. Ask the children to reach into the hole and grab the red dates, count the red dates and calculate how many red dates are left in the box.
4. In the game "Little Horse Delivers Food", the children are divided into two teams to play the role of Little Horse Delivers Food. After the teacher gives the order, the two teams run to the "Little River" and pick up a bag of food. "The food is affixed with the questions of addition and subtraction within 10, and the children fill in the answer after the equal sign, and then run to the" granary "to put the food bag in the granary, and then put the second child in each team.
Third, group activities.
1. Two-color disc game. After children operate two-color discs to complete the formula, fill in the number in the box.
2. Poker game, children play cards in pairs 1 to 10, and each of them draws a card, which is bigger than the other, and subtracts the small number from the large number, or combines the two cards to form an addition formula.
3. Chess game. 2-4 people play a flying chess game in a group, and each person throws it twice. The sum of the displayed points is the number of steps the plane has to take, and whoever reaches the midpoint first will win.
4. Summary of communication:
Guide children to freely express their feelings after the game, and collect and sort out materials.
Activity reflection
We often say that interest is the magic weapon for students to learn. How to really use this tool in class is a problem for our teachers. I think it is necessary to adopt various teaching forms to stimulate students' happy study according to their own characteristics. In this lesson "Review/KLOC-Addition within 0/0", I adopted the following measures:
First, design math games to make students enjoy it.
According to the psychological characteristics of junior students, I pay attention to cultivating students' interest in learning mathematics and constantly stimulating their desire for knowledge. They like playing games best. It should be an important form for junior students to learn by doing, playing and having fun. Therefore, I always use games throughout this class.
At the beginning of class, I didn't use the previous formula of 10 to review, but filled the formula into the songs that children are familiar with to review, which is bound to be better than answering questions with students blindly. In order to test students' mastery, we can organize interactive games between teachers and students. I play "looking for kittens" with my students. I dress up as a kitten and meow a few times, and then the students make up 10 according to my meow. This is lively and interesting, and it also improves students' ability to distinguish right from wrong. It's a good way to kill two birds with one stone. Through some games, students will feel that learning is energetic, fun and rewarding, and the emotion of loving mathematics will naturally erupt.
Second, create problem situations, so that students can broaden their thinking.
Wonderful question situations are very attractive to these students. In teaching, I design question situations that can attract students according to the content of teaching materials, so that students can actively participate in mathematics activities to gain knowledge, develop their thinking and enjoy beauty at the same time.
Students' imagination is rich and colorful. Show a picture for students to talk freely and simply pass by, which reflects the main position of students' learning and the leading position of teachers. As soon as the next few pictures are presented, the students in group A can basically understand the meaning of the question by themselves. Furthermore, when I show the learning materials to the students, I leave them some room for thinking, so that they can deeply feel the profundity of knowledge and stimulate their interest in further study.
Teaching Plan 8 Activity Goal of "Addition within 10" for Mathematics Activities in Large Classes
1, on the basis of understanding the three elements of application questions, learn to add application questions within 10.
2. Improve children's hands-on operation ability and language expression ability.
3. Train children's thinking abilities such as listening, analyzing, understanding and judging.
Activities to prepare
1, learn before class 10, and add and reward stickers.
2. There are several addition formulas within 10, and the scene is arranged as a supermarket.
3, a small basket, 10 yuan money, change.
Activity process
First, the game "driving a train" leads to the topic.
Teacher: My train is about to leave. What time does it leave? The teacher showed a formula card: Please guess? Young: 1+6=7 Your train leaves at 7 o'clock.
The speed of the game is from slow to fast, from group games to group and individual games.
Today, the children's train is really good. The teacher will reward you with 10 yuan money and invite you to go shopping in the supermarket. It is required that one district can only buy one thing you like, and the total sum cannot exceed 10 yuan money.
Second, the game "shopping in the supermarket".
Children queue up in order to go to the supermarket to shop as required.
Third, the addition application problem within the oral 10.
1 Teacher's demonstration: Today, the teacher also went shopping in the supermarket. I bought a pen and spent money in 5 yuan. I bought an apple and spent money in 2 yuan. How many yuan did the teacher spend today? Children, help me figure it out! How did you calculate it? Let's think about what I said first. How about first? How about after? How many times have there been numbers? What's the final question? )
2. Three conditions for eliciting application questions: (Ask questions while operating on the blackboard, and record 5+2=7)
3. Teachers and children summarize what is the addition application problem? Teacher: How many questions together or one * * * are addition application questions?
4. Ask children to compile application questions according to the items they buy. (After group discussion, the group leader will answer)
5. Ask the children to list the application questions just compiled with formulas. Show children's formulas.
Fourth, combine the things around you to compile application questions.
1, teacher demonstration: There are 3 girls and 5 boys in the first group. How many people are there in the first group?
2. Guide children to compile application questions within 10 with the things around them. (discuss with parents) and make records.
3. Show the application questions of children's oral compilation.
V. Summary.
Today, we learned the addition application problem within 10. There are still many things around us that can be compiled into application problems. As long as you observe them carefully at ordinary times, you can become smarter.
