Design background of kindergarten lesson plan "Compare the size" 1 activity
Every time the fruit is divided, the children shout, "Teacher, I want a big one. Every time I take advantage of the situation, I take out two fruits, one big and one small, to compare with my children. Through observation and comparison, they can quickly tell which is big and which is small, but when I show two fruits of the same size to the children for comparison. They don't know how to describe "two fruits are as big" in words, so I specially designed this activity in the teaching and research class last semester, aiming at cultivating children's observation and comparison ability and learning to describe the size characteristics of objects.
moving target
1, preliminary training observation, comparison and reaction ability.
2. Compare the sizes of objects and learn to describe their size characteristics.
3. Develop visual perception and judgment.
4. Cultivate children's comparative judgment ability.
5. Interested in participating in math activities.
Teaching emphases and difficulties
Teaching emphasis: cultivate the ability of observation, comparison and reaction.
Teaching difficulties: through observation and comparison, find out the projects with the same size and learn to describe their characteristics.
Activities to be prepared
1, red and blue basin, some round pieces of paper.
2. A photo of a big bear and a photo of a little bear.
3. Some big clothes and small clothes
4. Some bowls
5. Some fruits, large and small.
6. A game box made of cardboard boxes. The game box has a big ball and two small balls.
Activity process
First, compare "big", "small" and "equally big"
1, the teacher showed the child a big basin and a small basin and said, What's the difference? Distinguish their sizes and say: the red basin is big and the blue basin is small.
2. The teacher showed several pots of different sizes, and asked one child to take out a pot at will, and the other child took out a pot as big as it. Repeatedly asked some children to come up and get pots.
Second, business activities
(1) Show the pictures of the big bear and the little bear, and let the children tell which one is bigger and which one is smaller.
1, the teacher took out clothes and asked individual children to find big clothes for bear and small clothes for bear.
2. The teacher took out the fruit and asked individual children to give the big fruit to the big bear and the small fruit to the little bear.
3. The teacher showed some bowls and asked individual children to come up and find the same bowl.
(b) group action exercises
Listen to the instructions and take pictures. The teacher shows several pieces of two kinds of graphic paper with different sizes, and gives instructions to ask the children to take a big circle, a small circle or a circle with the same size. The children immediately take out the corresponding circular paper from the table and lift it. Teachers' guidance can be diversified. For example, the teacher will say "big watermelon" and "small apple" when describing various objects, and the children will take out the corresponding circular pieces of paper.
Third, extend the game "Wonderful Box"
How to play: Please put your hand into the carton and feel what's inside. Guide the children to describe the shape of the touched object-is it the same or different? Then according to the teacher's instructions, take out the big ball or two balls of the same size correctly.
Teaching reflection
In this class, I can complete my teaching task according to my teaching goal. I make children the same size through a lot of objects. In the first stage, when I showed the pots to make the children the same size, most children could find out the big pots, small pots and pots of the same size through observation and comparison. In group exercise, it is a breakthrough in teaching and learning. I prepared a big green circle, a small yellow circle and two big blue circles for the children. During the operation, I clearly observed the development level and ability of each child. Most children can actively participate, but some children have unclear operational purposes. This may be because I have prepared so many circles for them that some children don't know how to hold them. In the third part of the game, I made some adjustments, and the child's interest was the highest. Through the extension of activities, children's understanding of size has been consolidated, but after touching the object, the child's description of the object is still not good. It is necessary to strengthen the training of language expression ability in the future.
"Compare the Size" Kindergarten Teaching Plan 2 Activity Preparation
1, 5 large blue tapestry disks, 6 small red disks and 7 small orange disks.
2. Paste the numbers 5, 6, 7 and the physical card.
Activity process
First, group activities.
1, show pictures one by one.
Please read the card carefully. What's on the card?
2. Correctly judge the quantity within 7.
Show me the picture 1.
(1) What is on the blackboard? Which color has the most discs? Which color has the fewest discs? how do you know
(2) Why do I think there are the most red plates and the least orange plates?
(3) Who can think of a way to change the arrangement so that we can see at a glance who has the largest number and who has the least number.
(4) Inspire children to line up the patches of each color. Now let's see who has the most and who has the least. Where did you see it? Guide children to compare three rows of discs one by one. Please tell the children how many disks there are in each row. Who sends digital friends to every row of discs?
3. summary. Want to know who is more and who is less, you can't look at the size of the object or the length of the queue. But to count how many there are in each row, in order to compare who has more and who has less.
Second, group activities.
1, the idea that prints the most numbers.
2, look at the tag sticker.
3. Fill in the blanks in order.
4. Add and delete comments.
5. Print less than 6 or 7 ideas.
The design background of "comparing the size" kindergarten teaching plan 3;
Children in small classes don't fully understand the characteristics of things, so I want to let children have a more comprehensive understanding of things through this activity.
Activity objectives:
1. Compare the sizes of objects and sort them according to the law of size.
2. Learn to describe the characteristics of objects by comparison.
3. Interested in participating in math activities.
4. Experience the fun of math group games.
Key points and difficulties:
Know the concepts of big and small.
Activity preparation:
PPT courseware, balls of different sizes (shoes, clothes, bottles, etc. ).
Activity flow:
First of all, know the big and the small
1. Show two balls of different colors and sizes, and let the children observe the difference between the two balls.
2. Which ball is bigger? Which ball is smaller?
3. Let children observe things around them or think about what they see, what is big and what is small?
Second, learn how to compare sizes.
Show two balls of similar size. Is there any way to know which ball is bigger and which ball is smaller?
Teacher's summary:
Teaching plan and reflection of small class mathematics with PPT courseware "comparing size"
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.
"Compare the size" kindergarten teaching plan 4 activity goal
1. Sort by size characteristics and match accordingly.
2. Experience the fun of math group games.
Activities to be prepared
The size of each ball is 1, and there is a picture and a sub-operation material.
Activity process
I. Introduction (Showing Big Bear and Little Bear)
Teacher: The teacher invited two guests today. Look! Who are they? Show me the picture (Bear). What's the difference between these two bears? Can you guess who is the big bear and who is the little bear? Why? (Big bear should be big, little bear should be small)
Teacher: You all know these two guests. How do you greet them? (Big bear is good, little bear is good)
Second, the intuitive proportion of physical objects
Teacher: Bear and bear want to do sports. Bring a ball (show a big ball). Who do you think this ball should be given to?
Do you think this ball is a big ball or a small ball? Why?
I'll bring another ball. Now please compare. Which ball is bigger and which ball is smaller? How do you compare it?
(Summary): It turns out that we can compare sizes with our eyes. One thing cannot be compared with size. Only by finding a good friend to compare with it can we know who is older and who is younger. (Visual method)
Third, children's physical exploration.
Teacher: Two bears, we brought a lot of things today. Shall we go and have a look together? What's there? Please find a big one and stick it on it with the sticker on your hand. Teachers talk and test with children.
Fourth, the order from big to small.
Teacher: Your little eyes are really smart. Now I'm going to make it harder to test you, huh? Here comes another ball. Now, of the three balls, please tell me which is the biggest and which is the smallest. Let one child line up from small to large, and then let another child line up from small to large.
Fifth, distinguish the size of the picture.
Teacher: Two bears are very happy. Here comes another bear. Now, please tell the children which bear is the biggest and which bear is the smallest. Please sort the children from small to large. Three bears are going to the zoo to find friends to play games. Look at what animal it is. Can you find the corresponding good friends for the three bears? Why?
Summary: Bears should make friends with big animals, bears should make friends with small animals, and the rest of the animals can make friends with the bears in the middle.
Six, children's operation and inspection
Teacher: There are many other animals in the zoo that are put under your stool. Please take it out and have a look Please raise your hand to shake the big animal, and then raise the smallest animal to shake it (children can paste it up). Now please help them find friends.
Teacher: You see, among bears, bears and bears have so many friends. Let's see if these animals are their good friends. (compare sizes. If you find any mistakes, please point them out and correct them. )
Seven. Promotional activities
Teacher: I'm tired of playing. I have two square biscuits. When you can't see big and small with your eyes, is there any other good way to know who is big and who is small?
At this moment, I had a good idea. We can overlap two biscuits and align them to see which one has more sides, so which one is bigger.
Now, please ask the children to take a biscuit in the back and pile it with friends of different colors to see who is older and younger.
Eight, dance game: three bears (with body movements to indicate size)
Teacher: Today, everyone is very happy. Let's learn the dancing movements of big bear and little bear. We use our bodies to represent the big bear and our contractions to represent the little bear. Let's dance together.
