1, according to the observation balance, light and heavy objects can be distinguished and the weight relationship between them can be understood.
2. Be able to express the calculation results in clear language.
First, the activity preparation:
1, fun math p8, pencil.
2. Video display stand and TV set.
Four, the teaching emphasis and difficulty:
According to the observation balance, we can distinguish and compare the weight of objects and understand the weight relationship between them.
V. Teaching methods and means:
Operation method and demonstration method.
Sixth, the teaching process:
Teachers' activities
Early childhood activities
Design intent
First, scene import.
Teacher: Little pig runs a fruit shop. Today, he wants to travel. He wants the children to look after the shop for him. Before leaving, piggy wants to teach the children some skills. Do you want to learn? Then let's learn technology from pigs today.
Listen to the teacher carefully and answer the teacher's questions.
The method of scene introduction can attract children's attention. Give it a preliminary impression of today's content.
Second, show "interesting mathematics" to explain and demonstrate.
1, (1) Teacher: Let's see what the pig asked us. Piggy wants us to compare the weights of two objects when the sky is uneven. Please look at the picture for comparison. Who is lighter or heavier, watermelon or apple? Tell me your reasons. Please tick the heavy fruit and triangle the light fruit.
(2) After the teacher has demonstrated a problem, let a child come up and do a problem.
(3) All the children have completed the first part of "Who is light and who is heavy".
2.( 1) Now pigs make it more difficult for us. Please check the balance status at this time. When an apple is as heavy as two bananas, please compare the weights of two objects with the same number. This requires a child's brain. Please think about it and tell me why you think so.
(2) Teachers give explanations and demonstrations under the video display stage. Tick under the heavy fruit.
(3) Guide children to complete interesting mathematical operations.
3, experience extension, compare four kinds of fruits, who is the heaviest and who is the lightest. The hook is the heaviest and the triangle is the lightest.
1, understand the teacher's explanation, listen to the teacher's requirements, and complete the rest of the comparison in the first part. Draw a tick under the heavy fruit and a triangle under the light fruit.
2. Observe the picture. Understand what it's like to compare different fruits with the same weight in the same balance. Complete the unfinished comparison independently.
3. Discuss and communicate, observe the pictures, and then compare them to find out the heaviest and lightest fruit.
1. Observe the state when the balance is unbalanced. Through experiments, we know that the two sides of the balance are uneven, and the sinking side is heavier.
2. Guide children to observe the balance and compare the weights of two different objects. Learn more about the weight relationship between objects.
3. Encourage the full expression of results in language, and then tell the results of mutual comparison.
Third, end the activity.
Teacher: Today, we learned a new skill from the pig. We learned to judge who is light and who is heavy by observing the scales. This method can also be used to measure when playing in the supermarket in the future.
You can listen to the teacher's summary quietly and have a certain impression on what you have learned, which can be used in your later life.
Help children consolidate what they have learned today by summing up.
Who is light and who is heavy on the classroom lesson plan 2 Activity objective:
1. Compare the lightness and heaviness of animals and understand the weight relationship between animals.
2. The result can be completely expressed in words. Initially, the results of mutual comparison will be inferred.
3. Cultivate children's spirit of trying and develop children's agility and logic of thinking.
4. Stimulate children's interest in learning, experience the happiness of mathematics activities and feel the fun of collective activities.
Activity preparation:
Some pictures of cats, dogs and pigs, three seesaw pictures and children's picture books.
Activity flow:
1. Show pictures of animals and lead to activities.
Teacher: "One day, a kitten, a big dog and a fat pig met. The three of them want to play seesaw, but they can't get on the seesaw. Huh? How do you usually play on the seesaw? Summary: It turns out that the seesaw is related to weight. Heavy sink, light rise.
2. Teacher: Do you want to help them and see who is light and who is heavy!
Let's see the cat and the big dog playing on the seesaw. Who will sink and who will rise? So who is lighter and who is heavier? Who will complete the sentence: who is lighter than who, who is heavier than who. Let's talk about it together Kittens are lighter than big dogs, and big dogs are heavier than kittens.
4. That's true. Now the big dog and the fat pig are playing on the seesaw. Who sinks and who rises? Why? So who is lighter and who is heavier? Who will complete the sentence: who is lighter than who, who is heavier than who. Big dogs add up to be lighter than fat pigs, and fat pigs are heavier than big dogs.
5. Teacher: "We have compared the weights of fat pig and big dog, big dog and kitten, but we still don't know who is heavier than fat pig and kitten. Do you know, children? " Which child will try it? Did he post it correctly? Yeah, give him a round of applause and praise him. how do you know Guide the children to speak completely: the kitten is lighter than the big dog, and the big dog is lighter than the fat pig, so the kitten is lighter than the fat pig.
6. Teacher: "We have compared the weights of fat pigs, big dogs and kittens. We want to see who is the heaviest and who is the lightest here? "
Second, feel the quantitative relationship between three small animals.
If 1 fat pig = the weight of two big dogs and 1 big dog = the weight of two kittens, then 1 fat pig = how many cats?
Teacher: Let's see 1 How many kittens is Fat Pig? (image)
Third, do "children's picture books" exercises.
1, the teacher sent a Children's Picture Book to introduce the problem-solving method to the children.
2. Let the children circle the heavy objects in the picture with a pen.
3. Look at the picture. Ask children to compare three kinds of objects in children's picture books, draw a check mark behind the heaviest object, draw a circle behind the lightest object, and draw nothing behind the light and heavy objects.
Fourth, summary.
Teacher: "today, we help small animals to compare who is more important, not who is lighter." When we get home, let's find some objects to compare with ourselves, and then come to the kindergarten tomorrow to tell the teacher, ok? "
Five, teaching reflection:
In the activity, I use courseware to make children lighter and heavier, and children can immediately reflect who is lighter and who is heavier when they see something concrete. But when asked why, many children replied that XX is heavier than YY because it is bigger than YY. Then I gave an example of a balloon (large volume) and a key (small volume) to refute their ideas. Most children immediately understood that their original ideas were incorrect. When I ask questions again, I will not judge by size, but can express them in more complete language: cats are lighter than dogs, and dogs are heavier than cats; The fat pig is heavier than the dog, and the dog is lighter than the fat pig, so it is concluded that the cat is lighter than the dog and the dog is lighter than the pig, so the cat is lighter than the pig.
However, in the process of children's own operation, many children can't do it independently, and they need the guidance of teachers to write correct answers, which is easy to confuse the relationship between the three. We need to strengthen this practice in future activities.
Who is light and who is heavy on the classroom teaching plan 3 Teaching intention:
With the growth of age, children in large classes are more and more fond of playing with and operating, carrying out simple activities such as comparison, classification, measurement and judgment, especially interested in the weight of different items in their surrounding lives, and like to try to compare and find their differences. "Who is light and who is heavy" is a math activity of the big class. It is intended to let children know the weight of objects through different natural measurement methods, and record their own calculation results correctly, so as to perceive the weight relationship between objects. Let children operate by themselves, find problems, solve problems and verify problems in exploration. Let children experience the joy of success in constant exploration.
Teaching objectives:
1. Feel the weight of two objects through visual inspection, experience and operation.
2. Guide children to try boldly and feel the relationship between light and heavy.
3. Cultivate children's reasoning ability and interest in learning and exploring.
4, preliminary training observation, comparison and reaction ability.
5. Let children learn simple math problems.
Teaching preparation:
1, all kinds of light and heavy items.
2. Two seesaw teaching AIDS and cartoon images of several small animals. Numbers and light and heavy signs.
3. Organize children to play on the seesaw outdoors before class to experience balance.
Teaching process:
Introduce the story first, and lead to the important questions.
Second, perceptual experience.
By lifting and weighing, guide children to perceive which items are heavy and which items are light.
Third, exchange and discussion:
1. What will happen if children are guided to put different items on the seesaw through their experience of playing on the seesaw? Why? Is there any way to make the inclined side sink? Guide children to imagine freely and express their ideas in words. The heavy ones hang down and the light ones tilt up. "(Learning vocabulary: vertical and vertical)
2. Say, which of the two objects is heavier or lighter?
Compare, who is the heaviest and who is the lightest of the three things? Guide them to classify.
Fourth, complete the exercises in the picture book.
Fifth, expand children's thinking.
How do you know the weight of an object in your life? What other ways to compare the weight of objects in daily life?
Teacher's summary:
Same size, different materials, different weights, same materials, different sizes and different weights.
The expansion of intransitive verbs;
Please play on the seesaw with mom and dad in their children's lives and compare who is the heaviest and who is the lightest among the three. Please rank the children.
Teaching reflection:
Children have a little understanding of the severity, so I will focus on the children's own operation in this activity, and find, solve and verify problems in exploration. Let children experience the joy of success in constant exploration. Experience the fun and success of comparing the weight of objects in different ways.
Who is light and who is heavy on the classroom teaching plan 4 Teaching purpose:
Let children learn to look at the scales and know that the heavy side is heavy.
Learn to compare which objects are heavy and which are light by looking at the pictures.
Key points and difficulties:
Compare the weights of three objects.
Modern teaching methods: scales, weighing dolls and children's picture books.
Teaching process:
First, explain the demonstration.
1, teacher: "children, today the teacher brought you a tool-Libra. What does it do? " The teacher showed the scales to the children and told them that the two ends of the scales were parallel, which proved that both sides were equally heavy.
2. Teacher: "The teacher saw pigs, puppies and kittens yesterday. They asked us to do them a favor. They said they wanted to compare who was heavier and who was lighter.
3, the teacher began to demonstrate, put the pig and dog at both ends of the scale, ask the child which is heavier, and teach the child that the object on the sinking side of the scale is heavy, while the object on the upper side is relatively light.
4. Then put the puppy and the kitten at both ends of the scale for comparison, and let the children tell who is heavier and lighter. Why?
Teacher 5: "We have compared the weights of pigs and puppies, puppies and kittens, but we still don't know who is heavier or lighter." Do you know, children? " In this part of the teaching process, the teacher guides the children to say that pigs are heavier than kittens, because by comparing with puppies, it is concluded that pigs are heavier than dogs and dogs are heavier than cats, so pigs are heavier than cats.
6. Teacher: "We compared the weights of pigs, dogs and kittens. We have to see who is the heaviest and who is the lightest here? " Teachers should let children learn to compare the weights of three kinds of objects and distinguish who is the heaviest and who is the lightest.
Second, do "children's picture books" exercises.
1, the teacher sent a Children's Picture Book to introduce the problem-solving method to the children.
2. Let the children circle the heavy objects in the picture with a pen.
3. Look at the picture. Ask children to compare three kinds of objects in children's picture books, draw a check mark behind the heaviest object, draw a circle behind the lightest object, and draw nothing behind the light and heavy objects.
Third, summarize the teacher: "Today, we helped the small animals compare who is heavier and who is lighter. After we go home, let's find some objects to compare and come to the kindergarten tomorrow to tell the teacher, ok? "
Activity reflection:
1. Libra is intuitive and the import is attractive.
2, can grasp the concept of children's weight, know how to teach them the concept of weight and the corresponding performance of the scale.
3, can do exercises in time, strengthen knowledge, and let children master knowledge better.
4. Some abstract questions are not prepared in advance. Inadequate preparation of teaching AIDS.
5, unfamiliar with children's picture books, did not introduce clear requirements to children.
Who is light and who is heavy on classroom teaching plan 5 teaching objectives:
1, distinguish and compare the weight of animals, and understand the weight relationship between animals.
2. The results can be expressed in words, and the results of mutual comparison are introduced preliminarily.
3. Understand the content of the story, remember the main plot and learn the simple dialogue of the characters.
4. Participate in reading and discussion, experience the strangeness and humor of the story, get a preliminary understanding of the character characteristics of the protagonist in the story, and further stimulate the interest in reading.
Teaching preparation:
1, courseware
2, "Children's Picture Book", pen
Teaching emphases and difficulties:
Understand the relationship between weight and weight.
Teaching methods and means:
Observation comparison method
teaching process
Introduce the topic first.
1. Show pictures of four animals and ask questions: One day, a kitten, a puppy and a fat pig met. They want to play seesaw, but they can't get up. Think about it, children. What is the reason?
2. The teacher concluded: It turns out that their weights are different, so they can't get up. Look at the courseware, observe and think about the reasons why the seesaw looks down on you. By observing the pictures, ask questions, arouse children's thinking and pay attention to the weight of animals.
Second, the scene shows:
Relatively light and heavy
1. The kitten and the puppy are placed on the first seesaw: Who do you think is lighter or heavier?
2. The pig and the dog are placed on the second seesaw: Who do you think is lighter or heavier, the fat pig or the fat dog?
3. Teacher: What will happen if the cat and the fat pig see the seesaw?
1, the children carefully observe the pictures put by the teacher and compare the quantitative relationship of the three animals. Baby theory: cats are lighter than dogs, and dogs are heavier than cats. Fat pigs are heavier than dogs, and dogs are lighter than fat pigs.
2. Children put cats and pigs together and express them in words: cats are lighter than dogs and dogs are lighter than pigs, so cats are lighter than pigs. The teacher guides the children to observe the pictures and think about judging the severity of the animals.
Third, homework and counseling:
The teacher used pictures to show the relationship between the weights of three animals:
1, Teacher: If 1 pig = the weight of two dogs, 1 dog = the weight of two cats, then 1 pig = how many cats?
2. Let the children do relevant exercises.
Children's operation, teachers' tour guidance.
1. Children observe the relationship between the weights of three animals.
2, children open the Children's Picture Book, according to the requirements, circle the weights in each group with a pen.
3. According to the weight relationship between the two animals, the balance method of seesaw is deduced. After children have been able to distinguish the light and heavy relationship between two small animals, guide children to feel the quantitative relationship between three small animals.
Fourth, summary:
Evaluate children's homework. Check and communicate with each other. Cultivate children's attitude of finishing homework seriously.
Teaching reflection:
In the activity, I use courseware to make children lighter and heavier, and children can immediately reflect who is lighter and who is heavier when they see something concrete. But when asked why, many children replied that XX is heavier than YY because it is bigger than YY. Then I gave an example of a balloon (large volume) and a key (small volume) to refute their ideas. Most children immediately understood that their original ideas were incorrect. When I ask questions again, I will not judge by size, but can express them in more complete language: cats are lighter than dogs, and dogs are heavier than cats; The fat pig is heavier than the dog, and the dog is lighter than the fat pig, so it is concluded that the cat is lighter than the dog and the dog is lighter than the pig, so the cat is lighter than the pig.
However, in the process of children's own operation, many children can't do it independently, and they need the guidance of teachers to write correct answers, which is easy to confuse the relationship between the three. We need to strengthen this practice in future activities.
Encyclopedia: Light is a Chinese character, pronounced qοng, which means light weight, shallow degree, small strength, relaxed and casual. Zhou Li
Who is light and who is heavy on the classroom teaching plan 6 Activity objectives:
1, explore the method of comparing the weights of objects in the problem situation, and clearly express the relationship between the weights of objects in language.
2. Simple reasoning can be carried out according to the schematic diagram of the light and heavy relationship of three objects on the balance to cultivate children's logical thinking ability.
Activity preparation:
1, apple, orange, black cloth, scissors, rubber, glue, a balance, record sheet, etc.
2. Some business materials.
3、PPT
Activity flow:
First, create a situation to stimulate interest
1, scene introduction: Two guests came to our class today. They are pleasant goat and beautiful goat. Welcome to visit. Pleasant goat is good, beautiful goat is good. But today, they are not happy about one thing. Pleasant goat says it brings weight, and beautiful goat says it brings weight.
2. Question: Show an orange and a piece of black cloth and let the children tell us how to know who is lighter and who is heavier. The big one is heavy and the small one is light. Weigh by hand, weigh by scale. )
Second, compare the weight and understand the relationship.
1, know the balance: the children speak very well, and the teacher has thought of a method that is accurate and convenient. Let's see what the method is, shall we? (Showing scales) Do you know what this instrument is, children? The name of this instrument is balance, which can measure the weight of objects. You can compare the weight of objects.
2. Weighing oranges and blackberries with scales, the conclusion is that oranges are heavy and blackberries are light.
Not convinced, Meiyangyang took out a black cloth and put an apple on the balance.
Question: Let's weigh it again and see which is heavier. We saw the apple sinking, so we weighed it with a scale. So apples are heavier than oranges.
Question: Now, children, which of the three fruits is the heaviest?
5. Summary: Apple is the heaviest and Blackberry is the lightest.
6. Teacher: Just now, Pleasant Goat and American Goat competed whose fruit was heavier. Next, let's see what is heavy and what is light in our classroom and record the results, shall we? Show me some scissors and erasers.
(1) Guess which is heavier and which is lighter, children? Let's weigh it with a balance.
(2) Teacher: According to the balance, scissors are heavier than rubber. (Tick the record after weight)
(3) Teacher: Remove the rubber and then expose the glue. See which is heavier, glue or scissors.
(4) Young: Glue is heavier than scissors. (Tick the record after weight)
(5) Teacher: Which is the heaviest, scissors, rubber or glue? (Tick the record after weight)
7. Summary: When comparing the weights of three objects, compare the weights between them first, and then compare the heavy object with another object. Do you remember, children?
8. Discussion: The teacher is here to test everyone. The teacher prepared some building blocks and iron. Would you please help me weigh which one is heavier and which one is lighter?
9. Ask a child to demonstrate in front. First, put a building block and iron at both ends of the balance. It is found that one end of iron is heavier. How does the teacher guide the two ends to be equally heavy? Add blocks at one end of the block until the two ends are balanced.
10, summary: after reading the weighing of building blocks and iron, it is found that large objects are not necessarily heavy and small objects are not necessarily light.
Third, homework exercises, summary comments
1, explaining the requirements of homework practice.
2. Organize children to do homework exercises.
3. Job evaluation
There are many serious examples in life, which we can compare by watching, weighing and weighing again. On Sunday, I will find some favorite objects around us with my parents and record them, ok?
Teaching reflection:
Children have a little understanding of the severity, so I will focus on the children's own operation in this activity, and find, solve and verify problems in exploration. Let children experience the joy of success in constant exploration. Experience the fun and success of comparing the weight of objects in different ways.
