2. Ability goal: to cultivate students' practical ability, judgment ability and cooperation and communication ability through learning.
3. Emotional goal: cultivate orderly thinking and good living habits.
Teaching emphasis: learn to classify according to certain standards.
Teaching difficulties: different standards can be used to classify.
Teaching Preparation: Courseware Learning Tool
Teaching process:
First of all, stimulate thinking:
Teacher: Students, do you have your own room? Who tidied it up by themselves? Please raise your hand. Let's look at the effect of students' finishing.
Our good friends Naughty and Xiaoxiao also have their own rooms. Do you want to see it?
This is a naughty room, this is a smiling room, what are you trying to say?
Today we will help naughty clean the room together.
Second, enlightenment.
1, everyone says the room is clean and tidy. Let's see how she arranged it. Learn from her good method and help the naughty boy clean up, will you? Health: Good!
2. What's in Xiaoxiao's room? Why did she put so many things?
Do you know why she put the ball with the teddy bear? Think about it. What are they for? (Introduce three categories: clothing, school supplies and toys)
4. We can see that Xiaoxiao classifies items with the same purpose into toys, school supplies and clothes. This is: classification.
Third, exhibition thinking.
1. Let's look at the naughty house again. It seems that naughty people, like most of you, don't pack their belongings. The teacher brought something from the naughty bag to class today. Let's see what it is. Which category should I put it in? Why do you put it in this category?
For example, this is a pencil for study, so it is placed in the school supplies category.
2. What's this? Which category should I put it in? Why do you put it in this category?
(socks, teddy bears ...)
Teacher: Now you have all the things left in the naughty room. Please think about what kind of items you want to post. Why is it posted in this category? Stand in a row when you are ready and post these items on the blackboard in categories.
Let's look at each kind of items in the naughty bag. (Original reading)
6. After your arrangement, what has become of the naughty house?
7. What kind of pencil should I look for when I am naughty? Where's the toy car?
8. Naughty mother bought story books again. What kind of box do you put them in? Why?
9. When winter came, my mother bought a scarf for Naughty. What kind of container should I put it in? Why?
10, what do you think of the benefits of current classification?
Fourth, promote thinking.
In fact, there are many classifications in our lives. Let's look at (the classification of appreciation in life).
Verb (abbreviation of verb) toth
1, learned classification today, and helped naughty clean up the room. Did you gain a lot? Dare to accept the challenge?
Let's start today's sunshine trip together!
A ray of sunshine:
Can you classify the following animals according to whether they can fly?
(2) the light shines:
Teamwork: Can you classify the following items? Tips:
1, take out the school tools in the study bag and say what items are there in the group?
2. Group discussion. How do you want to classify them? Tell me your reasons.
(3) unlimited potential:
Please classify the following figures. (shape, color, size)
I believe you will benefit a lot from this lesson. Use your smart eyes and flexible brain to discover the classification in life.

Teaching content:
Teaching objectives:
1. In specific cases, explore and master the calculation method of two-digit plus one-digit carry addition, and further understand the diversity and diversification of calculation methods.
2. Understand that when a number adds up to ten, it should be an arithmetic of one to ten, and master the vertical writing format of carry addition pen calculation.
3. Further understand the meaning of addition, feel the close connection between the operation of numbers and life, and improve the ability to solve simple practical problems by using what you have learned.
Explore and master the calculation method of carry addition of two digits plus one digit, and realize the diversity of calculation methods.
Understand the operation of different algorithms, especially the operation rules of all decimals into one.
Teaching preparation:
Teacher: Courseware
Student: Class exercise books, sticks and counters.
Teaching process:
First, create a situation to stimulate the introduction of interest
Courseware shows the photos of Jinjiang Children's Library, introduces the library and leads to the topic.
Second, independent exploration, cooperation and exchanges
1, observe communication and ask questions.
Show the theme map in the courseware, ask students to observe the map, understand the mathematical information, then put forward mathematical questions according to the information and write them in the classroom workbook.
The whole class exchanges questions raised by students.
2. Explore arithmetic and experience diversity.
(1) Solve the problem: How many books are there in the fairy tale world and the jungle world?
List formula: 28+4
(2) Let the students do a calculation in their favorite way, write it in the classroom exercise book, and then exchange their own algorithms with the deskmate, and the teacher will patrol to understand the situation.
(3) the whole class communication algorithm
Method 1: Put a stick.
Method 2: Call the counter.
Method 3: 8+4= 12 20+ 12=32.
Method 4: 28+2=30 30+2=32.
Method 5: column vertical style (what should students pay attention to when they name the column vertical style? )
(4) Compare and discuss the simplicity of the algorithm.
Method one and method two are more intuitive, but they need physical help; The latter three methods are relatively simple.
Third, choose the algorithm to consolidate the application.
1. Solve the problem: How many books are there in fairy tale world and underwater world?
2. Solve the problem: How many books are there in Fairy Tale World and Mimi College?
Ask the students to choose a simpler algorithm, name the students and talk about how they calculate when correcting collectively.
3. Do a longitudinal calculation.
58+7= 5+32= 38+6= 8+27=
Fourth, self-evaluation, class summary
What do you think of your performance in this class? What did you get?

Emphasis and difficulty in teaching
I have experienced the process of abstracting numbers from the scene diagram and then representing them with a dot diagram, and I have a preliminary understanding of the way of sequential counting.
Prepare multimedia courseware as teaching AIDS, etc.
teaching process
First, the creation of situational interest
Dialogue: Children love to play. Where do you want to play most? In this class, the teacher will take the children in our class to the children's playground. Students close their eyes and then open them. At the same time, the courseware shows the situation map of children's paradise. )
It is children's nature to love to play, especially for students who have just entered the first grade. Playing in children's paradise is the introduction to fully stimulate their interest in learning and let them invest in a learning state from the beginning of class.
Second, the maintenance of independent exploration interest.
1, preliminary perception
(1) Question: What did you see in the children's playground?
Send it again and again.
(2) Description: In the bright sunshine, trees are shaded, flowers are in full bloom, birds are singing happily, butterflies are flying happily, and children are so happy. Some of them ride wooden horses, some swing, some fly in small planes, and some slide on slides.
Emotion is the catalyst of classroom teaching. Expressive language can stimulate students' emotions and deeply experience amiable teachers and lovely classrooms.
2. Counting communication
(1) Question: There are many things in the children's playground. Can you count how many there are?
(2) Students count themselves first, and then count them to their deskmates.
(3) Choose a few students as guides and lead the rest of the children to count in order.
3. Summary method
(1) Discussion: How to count correctly and quickly?
Discuss in groups and communicate collectively.
(2) Summarize and emphasize the sequence number one by one. (From left to right, from top to bottom, and so on. )
4. Practice answering questions first
(1) Question: 1 ... Student answer: 1 slide; 2 ... Students pick up two swings ... (Courseware demonstration, extracting 10 fragments from the theme scene one by one)
(2) Look at the picture and say that the picture means: 3 wooden horses. ...
5. Bitmap represents numbers
We can use some of the simplest symbols to represent the number of objects. What do you want to represent? Let's use the concept map, shall we? 1 slide is represented by 1 idea (there are 1 idea in the presentation). How to express the number of swings? Why? How to express the number of wooden horses and planes? What else do you have in mind? (Let the students speak fully)
Inquiry: How many objects do seven points represent? What do the eight concepts mean? How to express the number of balloons? 10 What does the idea mean?
Third, the experience of entertaining.
Transition: Children, the beautiful campus is our paradise. Let's go to the children's playground to play together! (Leading the students out of the classroom and into the campus) Find some dolls. There are many dolls hidden in the beautiful campus. Do you want to find them? Find good friends (including teachers) and communicate with them.
Practice the number of ideas (create a specific scene before class)
1 Snow White, 2 handkerchiefs, 3 mushroom slices, 4 flowers, 5 baskets, 6 apples, 7 dwarfs, 8 teacups, 9 pears and 10 small bowls.
Beautiful fairy tale scenes and students' favorite fairy tale characters are learned vividly and practiced with relish.
Fourth, summarize the extension of increasing interest.
Dialogue: Mathematics is closely related to our life. Every member of the mathematical kingdom is winking at us with intelligent eyes. Do you want to make friends with them? What are you going to do in the future? Students can speak freely.
[The first math class should educate students about the purpose of learning. Take making friends as a metaphor to educate students to love, miss and miss mathematics. Achieve the purpose of extending students' interest in mathematics. ]
