I introduction (composition of review 5)
Teacher: The king of the animal kingdom invited us to visit his country. Would you like to?
But we can't go until the code is unlocked. How does five break down into two and several?
Second, situational awareness-being a guest: the addition of picture learning 5.
1. Teacher: Children, the animal kingdom has arrived. Let's go to the small animal museum. Be careful not to be bitten by animals.
Look at the picture and count the additions within 5. If you count animals as gifts for children, if you count them wrong, you will detain the children.
If you are quick, you can go to the homes of some small animals. Write your answer clearly.
ask questions
(1) Teacher: What problem did you encounter just now? (4 sentences and 4 pictures)
What's your answer? (Formula for Children's Column)
Teacher record
(2) Teacher: Let the children observe these formulas. "They have a little secret, so who can find it first? summary
Teacher: The numbers of these formulas are all 5 at www. 163ed.com, and they are all addition, so these four formulas are all addition formulas of 5.
Like 1+4=5, 4+ 1=5, the number of these two formulas is the same, but the position is different, but the number remains the same.
So when we see 1+4=5, we immediately think of 4+ 1=5. We call it the friend problem. Similarly, when we see 2+3=5, what do we think of?
Third, consolidate and deepen.
1. Teacher: Small animals all praise us for being smart. We all have toy tickets given to us by animals to show the price.
You have 5 yuan money. You can buy those two toys. What will you buy and why? Can I still buy those two?
2. Pediatric surgery
3. Summary:
(1) There are several methods. What do you buy?
(2) What if I buy three kinds for five dollars?
Fourth, summary.
We learn the formula on the blackboard:1+4 = 5,4+1= 5,2+3 = 5,3+2 = 5.

Teaching reflection:
Through this teaching activity, I learned that children's mathematics is very weak. In order to make them interested in math, I'm going to add more games in future math activities, so that children can have fun and learn from each other while playing. Really let children become the masters of learning and constantly improve their independent inquiry ability.
Junior high school mathematics "5 addition" teaching plan 3 activity goal

Activity process
First, import.
Children, let's go to a fun place today. Let's go! Birds are chirping and rabbits are jumping. It's really lively in the Woods today, huh! Who is here? 1 oriole singing in the trees. Four orioles are dancing. The children told me that a * * * is five birds.
Birds are chirping and rabbits are jumping. It's really lively in the Woods today. Four orioles are chirping in the tree, 1 orioles are dancing. The children told me that a * * * is five birds.
prologue
Birds are chirping and rabbits are jumping. It's really lively in the Woods today. who is it? Two white rabbits are eating grass and three white rabbits are dancing. The children told me that a * * * is just a few rabbits.
Birds are chirping and rabbits are jumping. It's really lively in the Woods today. Three rabbits are eating grass and two rabbits are dancing. The children told me that one rabbit is five rabbits.
Second, study.
Oh, here we are. Where is this? Dwarf's home. How many dwarfs are there here? Show me the number 1. Dwarfs are really naughty and like to play hide and seek. The dwarf will come out soon, and some children will come to play with you. Oh, the dwarfs are out. Look how many dwarfs have come out. Show me the number 4. How many dwarfs are there? Show me the number 5. What symbols shall we use together? Show me the symbol+,a * * * useful =. Read together: 1+4=5.
There are trees in the yard of the dwarf's house. There are 1 big leaves here and 4 small leaves here. There are five leaves in all. What formula is used to express it? 1+4=5。 That's great!
Look! The flowers in the dwarf's house are blooming. They are really beautiful. Tell me how many? 1 flower is hidden here! Four big flowers, 1 small flower, add up to five. What's that look? XXX, please come and help me. 4+ 1=5。 Let's read it together: 4+ 1=5. Now, please look at these two formulas carefully and tell me what you find. You really read it carefully. The original position has been exchanged, and the result is still the same. Children say together, the position is exchanged, and the result remains the same.
Smell it. What smells so good? Let me go to the dwarf's kitchen. Oh, it's the dried fish made by the dwarf. Smell it. It's very fragrant. The children will smell it, and I will smell it for the dwarfs. The dwarf told me that it really smells good. Look at these dried fish. There are two big fish. Show me number two, three small fish and number three. There are five fish together, which can be expressed by formula 2+3=5. Let's read together. In fact, this formula can be changed, can it? Who will help me? Let's read 3+2=5 together, I see, that is, switch places, and the result remains the same.
Third, operation.
In fact, dwarfs still have delicious food. Look, this is the orange salad made by the dwarf. It looks delicious. Do you want to eat? The dwarf said, only one plate is not enough, but we can make our own fruit salad. Look, what kind of salad do I want to make, apple salad, and how, can I do it? Apple salad needs five apples to make. How many big apples and how many small apples do you want to use? Two big apples and three small apples, we can stick the apples on the plate. First, tear off the double-sided tape on the plate with your little hand and stick two big apples and three small apples, making five apples in all. What is the formula? Ok, let's write the formula 2+3=5. What else can I do with this salad? What is the formula? Your salad is great! What else can I do? What is the formula? Your salad is different from others'. You are so clever. How else can I make this salad? You're amazing! Next, we are going to make salad together. Remember that everyone can make four different salads in four different ways, and don't forget to use expressions. Come on, let's make salad together.
Teaching reflection:
Some teaching objectives of this open class have not been fully considered, and they have not started from the actual situation of the class. The attendance rate of children in the class is not very good. Some children have learned the addition of 5, while others have not yet learned it. If your goal is to add less than 5, I will give you a good review class. In addition, your psychological quality needs to be strengthened. You are a little nervous during class, and you forget to talk about the pre-arranged content because of nervousness.
Teaching plan of "addition of 5" in junior high school mathematics IV. Activity objectives
1, deepen the understanding of numbers in operation and improve the ability of calculating and writing application problems.
2. Understand the meaning of addition and subtraction by operating the "addition and subtraction board".
3. Take an active part in games, use your brains to think and experience the fun of math activities.
Second, the activity preparation
1, teaching aid preparation: addition and subtraction board; A box; PPT courseware for addition and subtraction within 5; Music.
2. Preparation of learning tools: addition and subtraction board; Add and subtract the number of envelopes within 5; There are several animal headdresses with formula questions written on them.
Third, the activity process
1, at the beginning. Game: touch the ball game. (Review the decomposition of numbers within 5) The teacher shows a treasure chest and lets the children guess what's in it. There are number plates 2-5 in it. ) The teacher reached in and touched one, and then asked the child how much it was. After the child answered, the teacher said, "Let's play a game of touching the ball, a total of five." Kid, let me ask you, how many balls did my two balls touch? Miss Tingting, I tell you, your two balls hit three balls. Draw cards twice in a row and play three times.
2. Basic part.
(1) Breakthrough game. The teacher plays PPT to let the children break through some topics. A total of 5 levels, each level is successful, and the teacher rewards the children with big smiling faces. Until the end.
(2) Challenge the game. Complete the formula problem of the envelope. Ask the children to help the teacher figure out the number of formula questions on the envelope. Two children work together. One child operates the addition and subtraction board, and the other child is responsible for recording numbers. Which group of children can finish it fastest will get the teacher's reward smiling face.
3. The last part. Game: small animals find homes. Let children help small animals find their own homes. Every small animal has a recipe problem. Find the corresponding house number after counting the numbers. The teacher drew five numbered circles in the classroom in advance, and the children began to find a home while listening to music. When they hear the music of wolves, if they don't find a home, they will be eaten by wolves. Children exchange headdresses, and the game can be played twice, depending on the time.
The teacher concluded: "Today we reviewed the addition and subtraction within 5. Children behave well and can test their parents when they go home. That's all for today's class. Please put the headdress gently in the basket. "
Activity reflection:
In order for children to calculate their mouth correctly and quickly, they must also be trained regularly through various forms of practice. I actively advocate the diversification of algorithms and provide opportunities for children to communicate in mathematics. The purpose is to promote children's mathematical thinking activities and improve their mathematical thinking ability. Because of the diversity of algorithms, different children have different problem-solving strategies. They will use their own methods to solve problems and have a deep understanding of solving mathematical problems, thus gaining experience in learning mathematics. These algorithms are the result of children's thinking according to their own basic knowledge and life experience. Each different algorithm represents a sense of innovation, thus effectively training divergent thinking.

According to three children watering flowers and two children carrying water, the teacher wants to ask a math question. (How many children does * * * have? )
2, lead to the topic:
The teacher asked: ① Three children are watering the flowers and two children are carrying water. How many children are there? That is to say, three children and two children are together. We will use addition to calculate, (blackboard title: addition) Reading: addition. In addition to calculation, we also need to use a new symbol: "+",which is called the plus sign (blackboard writing: 3+2). Repeat after the teacher: plus sign.
Teacher: Can you tell me what the plus sign means?
The plus sign means to combine the two parts and find out what * * * is.
(2) three children plus two children, a * * * how many children? (5) The teacher writes on the blackboard: = 5
How did you get five? (Children may have the following algorithms. Children can't speak, and teachers and children count together. )
A Let's count them together (referring to the drawing number 1, 2, 3, 4, 5,)-* * There are five.

Teacher: Then let's begin! (Computer courseware demonstration: Beautiful Swan Lake)
Blue sky and clear water, how beautiful the scenery here is. Look, there are some beautiful swans in the lake. Please carefully observe the changes in the picture, and then tell the children what you see and think, ok? (Courseware dynamic demonstration: Another swan flies over the beautiful Swan Lake and slowly falls (Figure 2) to join the ranks of swans. )
Health: There were four swans in the lake, 1 swan flew in.
Teacher: You really use your head. Please think about it, how can we find out how many swans are in a * * *?
Teacher: The children in Class 2 are so smart. Do the animals want to study with you? Would you like to? (willing).
Courseware 2: Look at the picture carefully. Let's see who is the cleverest. Who can express the meaning of the chart with a formula?
Teacher: Click to summarize the children's answers.
Fourth, children's hands-on activities.
Small animals say that children are really smart! They want to compete with the children to see who has the best hands-on ability and who has the best skills. Now, children take out your digital card bags, put the four numbers 1, 2, 3, 4 given by the teacher, arrange several addition formulas with cards, and record the results on the exercise paper.
Game: Help Xiaoye find the mother tree.
How did the leaves on Guo Hua Mountain float here? It turns out that the baby leaves are separated from the mother tree, and the baby leaves must be very scared. Do something, children. Help Baby Ye, will you? Let's see what's on Baby Ye. There is a telephone number, which is an addition formula. Children can help Ye Baobao find the tree mother by counting numbers.
Children operate to hang leaves on a corresponding number of trees.
Six, the game: driving a train
Who's calling? Oh, Wukong called and invited us to visit water curtain cave. Are you happy? Shall we go by train? The teacher gave each child a train ticket, and the children worked out their own car numbers, got on the same car according to the numbers, and lined up behind the children wearing headdresses in an orderly manner. (You can't get on the train if you make a mistake), and you can also drive the train out of the classroom to the music of driving the train.
