1. Skillfully use the addition and subtraction within 10, and understand that the same answer can correspond to multiple questions.
2. Be familiar with some important telephone numbers in life and be willing to know the contact information with your companions.
Important and difficult
1, proficient in addition and subtraction within 10.
2. Be familiar with some important telephone numbers in life.
Activities to be prepared
1. 10+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0.
2. Carry out thematic activities? I'm going to primary school? Children have a desire to know the contact information of their peers.
Activity process
First, the guiding part: review the addition and subtraction within 10.
Teacher: Our children will graduate soon. A few days ago, we all talked 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 telephone numbers.
(1) Decipher the phone number by reading the questions.
The teacher shows a digital card consisting of eight addition and subtraction problems, such as 3+3, 7-4, 8+ 1.
This link is to help children review the addition and subtraction within 10.
During the activity:
The teacher asked questions from many angles, such as what is the first number of this mobile phone? What number is it? 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 together? What's the phone number of the kindergarten?
(2) Psychologically deciphering telephone numbers.
1. The teacher showed the second telephone password and asked: Do the math in your mind and keep the answer in your heart? Wait a minute. Let's talk together.
2. The teacher showed the third telephone password, demanding that it be deciphered accurately and quickly, and deciphered the telephone password at once.
Second, the learning part: set the password for the phone number and decode it.
(1) Calculate the answer according to the formula.
1. Divide the children into four teams: red, green, yellow and blue. Each team has 10 phone numbers? In the form of group competition, compare which team has the greatest ability to decipher the phone number 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 compile the questions according to the answers.
Division; Here are three very special phone 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). O this link guides children to understand that an answer can correspond to many types of questions, for example, can? 1 19 One set of codes for bamboo weaving: 4-3, 7-6, 2+7. Kitchen samples can also be woven into 7- 5+2-3, 5 -2- 2, 1+5+3 and so on.
1. The children try to ask questions in groups.
These groups exchange questions with each other and decode them.
Please post the decoded phone number on the blackboard.
10 teaching plan design within the second part
moving target
1, stimulate children's interest in participating in mathematics activities, and cultivate children's feelings of unity, cooperation and caring for others.
2. Cultivate the agility and flexibility of children's observation and thinking.
3. Review and consolidate the addition and subtraction within 10.
Activities to be prepared
Several digital cards, addition and subtraction cards within 10, telephone number contact cards, pencils and erasers.
Activity process
1, playing games? Touch the ball? Review the composition of numbers within 10.
Teacher:? Let's touch the ball. My ball and yours add up to 10, 9, 8, 7, 6, 5 and so on. ?
According to the child's mastery, speed up or slow down accordingly.
2. Let the children say their home phone numbers and arrange them with digital cards.
The teacher asked individual children to make up corresponding addition and subtraction formulas for each number.
Guide children to think and discuss what is the telephone number of kindergarten? Add the addition and subtraction formula of the corresponding number to each number.
3. Team games? Call? .
(1) The teacher provides each group of children with a phone number sheet. Each child answers a question, writes the number in the blank space of the next line, and passes it on to the next child. The last child gives the complete phone number.
(2) After each game, teachers and students * * * check whether the figures are correct and give encouragement to the completely correct ones.
(3) Then change the number paper and continue the game.
4. Design a test card with your home phone number and exchange oral calculations with your partner to see who can correctly say the phone number of the other person's home.
Teaching Plan Design Part III Addition and subtraction 10 or less

Second, practice
1. Every morning, the teacher drives to work. I found some interesting phenomena in the car. Let's go and see them.
Courseware display: bus map
There are four people in a car, three people get on first, and then two people get on. How many people are there now?
Look how many people have come down. Where did it come from? How many other people have you fucked?
2. Can you tell a complete picture?
Students are really good at thinking. It turns out that there is so much math knowledge in our life. You should observe more and find more mathematical knowledge in the future.
3. Can you make a formula?
Third, consolidate the application
