How to take the open class of addition within 10 in large class mathematics

Objectives of the class calculation activity "Happy Mathematics": 1. Review addition and subtraction within 10, try to read the pictures orally and understand the operations. 2. Cultivate children’s awareness of cooperation and competition and experience the charm of mathematics. Activity preparation: 1. Several addition and subtraction cards within 10, several addition pictures, and 5 oral pictures. 2. Three answering machines (drums, waist drums, gongs), one statistics card, and one picture each of Donald Duck, Mickey Mouse, and Little Bear. 3. Several fruit cards, one firework, and one piece each of victory, failure, and cheerful music. Activity process: 1. Introduction questions 1. Teacher: Children, welcome to the Happy Mathematics Camp. I am the host of the Happy Mathematics column - Little Question Mark. The slogan of our column is: Happy Mathematics, Unlimited Happiness! We now shout out the slogan loudly: Happy mathematics, unlimited happiness! Ye! First of all, I want to introduce to you the three teams today. The one with Mickey Mouse on it is the Mickey Mouse team. Welcome! Anyone with Donald Duck on it is Team Donald Duck, welcome! Those with Cubs on them are Cubs, welcome! Mickey Mouse, Donald Duck, and Little Bear all like to eat fruits. Today I have prepared a lot of fruits for you. Do you want some fruits? Then we will immediately enter the first level of Happy Mathematics. 2. The first level of happy mathematics. 1. Teacher: Level 1: Must-answer questions. Each contestant of the three teams has to answer a question. For each correct answer, a fruit will be awarded. There are no rewards or penalties for wrong answers. But you have to answer it yourself. The player who gets the fruit must pick up the fruit and put it on his team's hero list. See which team has the most fruits. Now ask the No. 1 player from each team to answer the question. 2. Teacher: Let’s start answering the questions. Please listen to question 3 3=? (The teacher asks three contestants to take turns to answer) Children: 3 3=6 Teacher: (Show the correct answer) If the answer is correct, so-and-so and so-and-so will get fruit rewards. 3. Teacher: Now let’s ask the No. 2 player from each team to answer the question. (Proceed in order) Summary: The six rounds of required questions in the first level are over. Let’s focus on the number of fruits obtained by each team. How many fruits did a certain team get? Can it be expressed by how many numbers? (Teacher writes on the blackboard) Children, which team has the most fruits? The Mickey Mouse team is currently in the lead, but Donald Duck and Little Bear don't be discouraged. You still have a chance in the later stages. Now we enter the second part of today (reprinted from the first essay website, please keep this mark.) - Happy Mathematics, the second level. Ye! 3. The second level of happy mathematics. 1. Teacher: The second level is "I say you do the math". Today I brought a picture and I made up a paragraph for it. Please count, how many small animals are there in my picture? (There are two butterflies in the garden, and two more butterflies fly in. How many butterflies are there in one day?) Children, please count. 2. I have another picture here. Who can write a paragraph for it like me and let me do the calculations? (1) Children can discuss freely and ask children to speak orally. (2) The teacher tells the story in full and writes on the blackboard: 2 3 = 53. I have three pictures here, one for each team. Please compile the pictures into a paragraph and keep the answers quietly in your heart. 4. The challenge begins: Team Mickey Mouse can choose a team from Donald Duck or Cubs to accept the challenge. Teacher: Who do you choose? Team Donald Duck accepts the challenge, please listen to the questions. (Any member of the Donald Duck team can answer the question. Whether the answer is correct or not is judged by the challenge team. Three clicks for a correct answer and one click for an incorrect answer.) Congratulations to the Donald Duck team for getting a fruit. Now let’s ask Team Donald Duck for a question. 5. Summary: In the second level, the three teams were well organized. I added a fruit to each of the three teams. Let's focus on the number of fruits for each team. (Praise the first place and encourage other teams) 4. Happy Mathematics, the third level. 1. The third level, quick answer questions. I'll show you the picture and you'll figure it out using numbers. For example: How would you calculate this picture: (2 3 = 5) Yes! This is how we calculate it. 2. I asked the number 6 of each team to be the captain, and asked the captain to bring out the musical instrument behind the stool to be the answering machine. When I showed the picture and said: the answering starts. NOTE: The captain must ring the buzzer after I say start. good! Prepare! The Q&A begins. 3. Summary: How many fruits does Team Mickey Mouse have in the Q&A session? How many fruits does Team Donald Duck have? How many fruits does Winnie the Pooh have? 5. Statistics 1. After the three levels, let’s look at the fruit scores of each team. (Children’s singing count, teacher’s statistics) Team XX got the most fruits, team XX and team XX also had a lot of fruits. Mickey Mouse, Donald Duck and Winnie the Pooh were very happy and sent us fireworks. Let’s celebrate together (the teacher threw out the fireworks). Jump up! 2. Ending: Now we go to the classroom to continue celebrating.
