Activity design:
1, arouse the interest in deciphering telephone numbers, and learn how to decipher them.
2. Stimulate children's interest in deciphering telephone numbers.
Teacher: "In a few days, the children will leave the kindergarten for primary school. Will you miss your teacher?
Health: Yes.
Teacher: So, is there any way you can contact me? "student: chat with the teacher online, write letters, and come to kindergarten to call the teacher. Teacher: Which method do you think is the most convenient? What's the fastest way to find me?
Summary: Calling is a good way to keep in touch, because it is very convenient and fast.
2. Decipher the phone number of the teacher's house: "Do you know my phone number?
Student: I don't know. Please tell us quickly. Teacher: The teacher made my home phone number into a password question. If you can decipher this password problem, then you will know my home phone number. How do we decipher it? Please answer each question here in order, and then my home phone number will be decoded. Everyone should decode it carefully. After decoding, we will call to verify.
Ask eight children to decipher a topic. The children have finished deciphering it. Let's check together and see if their questions are decoded correctly. The first question is (…). Let's read together. The second question is (…). Let's decrypt it together. This is (…). Finally, the number we deciphered was 59650836.
This number has been deciphered. Is it the teacher's home phone? Let's make a phone call and try. Who wants to? Let's ask … to have a try. The children help her read and dial the number. After dialing, please ... by the way, is this xu teacher's home phone? Excuse me, who are you? ......
Try to decipher the special telephone number division: the telephone number we deciphered just now is an 8-digit fixed telephone, not a home telephone. Are all the telephone numbers 8 digits? What other phone numbers do you have? (Mobile phone number 1 1, emergency phone number) displays the phone numbers of 1 10,19 and 120 respectively. Please decrypt the summary: in our life, sometimes some urgent things happen, and we can call when we meet different urgent things.
1, besides 1 19, 1 10, 120, what other special numbers do you know?
Question: What's the difference between these three phone numbers and home phone numbers? When do we dial these special telephone numbers?
2. Write down a friend's home phone number.
Teaching reflection:
Generally speaking, this class is clear. The children will leave kindergarten for primary school soon. Now the communication equipment is very developed, and many students have telephones and mobile phones at home. They usually contact their friends by phone and mobile phone, and of course they need the help of their parents. This class can make children know more about telephones and mobile phones, and can also increase their feelings through these activities. I answer the phone number by calculating questions, which can not only arouse children's interest in exploration, but also enable them to exercise their mathematical ability.
However, many children didn't answer the question correctly. It may be that they usually do less calculation problems and don't understand them thoroughly, so they need to be further strengthened and improved. My language in class is not very concise and needs to be improved. Get to know yourself through reflection after each class, so that you can make greater progress in future teaching.

Activity process
First, import:
Review the addition and subtraction within 10.
Teacher: Our children will graduate soon. A few days ago, everyone was talking about the contact information after breaking up, including writing letters, sending greeting cards, dropping in and making phone calls ... Today, we are going to play a game of deciphering phone numbers.
Second, unlock the phone number:
The teacher shows a number card consisting of eight addition and subtraction problems, such as 5+3, 4+4, 7-5, 4+ 1 ...
This link is to help children review the addition and subtraction within 10.
Activity: The teacher asks questions from many angles, such as what is the first number on this phone? What number is "6"? What is the last one?
Teacher: You are great! I deciphered the phone number at once. How did you decipher it?
Yang: It was decoded by addition and subtraction.
Teacher: Do you know whose mobile phone this is?
Young: kindergarten.
Teacher: You can call this number in the future if you have something to do or want to. Tell me the phone number of the kindergarten together.
Third, set a password for the phone number and unlock the password:
(1) Calculate the answer according to the test questions.
1. Divide the children into four teams: red, green, yellow and blue. Each team has 10 phone passwords. In the form of group competition, compare which team has the greatest ability, and the phone number can be solved quickly and accurately.
2. Exchange inspection for each group.
Please send a representative from each team to report the score of the other team.
(2) Try to write test questions according to the answers.
Teacher: Here are three very special telephone numbers. In the future, you should set passwords for these phone numbers within 10. Every number in the phone number is an answer. The password you made will be deciphered by other groups, so the harder it is, the better.
-At the beginning, the number provided by the teacher can be small but special (for example, 1 10, 1 19, 120). This link leads children to understand that one answer can correspond to multiple questions, such as "1 19 bamboo can be woven into a set of passwords: 4–3, 7–6, 2+7. It can also be composed of: 7-5+2–3, 5 -2- 2, 1+5+3, etc.
1. The children try to compile test questions in groups.
2. Each group exchanges test questions and decodes them.
Please post the same phone number as the one on the blackboard.
Four. Extension of activities:
It is suggested that the telephone numbers of teachers and companions be further coded.
Teaching reflection
The children were in high spirits and reacted strongly when compiling and unlocking passwords. They can take the initiative to speak, tell their own passwords and decipher their peers' passwords. So as to strengthen the mastery and flexible application of addition and subtraction and cultivate children's mathematical thinking and ability.
Deciphering telephone numbers Kindergarten lesson plan 3 Activity background:
The children in the big class are about to leave the kindergarten, and there is a feeling of reluctance among the children. During recess and after school, everyone likes to exchange phone numbers and strengthen contact. Combining the theme activity of "I want to go to primary school" in our class, creating life scenes and integrating mathematics education resources will help children learn mathematics in simulated life scenes, which will help them learn mathematics knowledge, form mathematics skills and learn to think and solve mathematics problems. The outline puts forward: "You can feel the quantitative relationship of things from life and games and appreciate the importance and interest of mathematics." Decrypting telephone numbers can meet children's needs of learning mathematics, and can effectively promote them to migrate their existing operation and record experience, and construct digital concepts in an autonomous and active state in the interaction with life situations. Based on the above understanding, I designed this activity to make children feel familiar and novel, which is not only in line with their realistic level, but also challenging.
Activity objectives:
1. In the activity of deciphering telephone numbers, sort out the addition and subtraction operations within 10 to improve the operation ability.

Teacher: If you want to make a phone call, you must know the phone number first. Do you know my home phone number? Do you want to know?
Teacher: The teacher made my home phone number into a password question. If you can decipher this password problem, then you will know my home phone number. How can I break it?
Teacher's summary: Please work out the answers to each question here in the order from left to right, and then my home phone number will be decoded.
2. Children's operation.
● You can't communicate loudly when deciphering.
● After decoding, take the password card and pencil and sit down.
3. Children exchange deciphering results.
● Let one child report the password and other children verify it. If they are the same, they will not be repeated; If not, tell me the first difference.
● Let a child call the teacher's home for a collective inspection.
Teacher: We have all decoded it. Have you deciphered all your password questions correctly? Let's test it together.
Teacher: Please ask one child to report the password first, and the other children will verify it to see if it is the same as yours.
Teacher: Is your password the same as mine? I asked a child to call my home phone number, and you continue to verify it.
4. Publish the deciphering results and call the teacher's home for verification.
Teacher: Do you remember my home phone number? Let's try one together.
5. Summarize the methods of addition and subtraction.
Teacher: Ah! You decoded my home number, you are great! Then how did you work out the passwords of these eight phone numbers so quickly? Is there a fast and accurate method to calculate?
The teacher concluded: the same arithmetic problem will not be repeated, which will speed up the calculation; In the addition problem, the two digits before and after the+sign are exchanged, and the number is the same.
Third, decipher the telephone numbers of Miss Gong and her friends.
1. Decipher the phone number.
Teacher: Every family's phone number is different, and the password is different when it is compiled. So will our quick and correct method work? Let's try to make up two more.
Teacher: Let's see whose phone number we cracked this time. Ask the children to tell the whole story
