1. Math courseware for kindergarten middle class: My friends and I are taller than each other.
Activity objectives:
1, learn to compare the heights of objects intuitively and perceive the relativity of heights.
2. Learn to arrange 2-5 objects from high to low or from short to high.
3. Be able to actively participate in activities and feel the pleasure of growing taller.
4. Cultivate children's ability to observe, judge and operate.
5. Guide children to actively interact with materials and experience the fun of mathematics activities.
Activity preparation:
Three pictures of roosters, five pictures of puppies with different heights, and five pictures of mushroom dolls with different heights, each with a sorting column.
Activity flow:
First, guide children to find that height should be compared at the same level.
1, teacher: (showing pictures of three cocks with different colors) Children, today the teacher invited three cocks to play games with the children, but they were quarreling and said yes.
Let the children help them find a way to tell who is tall and who is short, ok? (Children think) Please tell the cocks what you think and see if you can help them. (The child answers)
Er: All three cocks are standing on the same line. By comparison, we can know who is tall and who is short.
2. Sort from short to long.
Teacher: Can you arrange them from short to high? Put it on the sorting board. (Display the sorting board)
3. Compare the teacher with the child, then compare the teacher with the tall teacher, and guide the child to discover the existence of height through comparison.
Summary: I want to know who is tall and who is short, depending on who he is compared with. When he is compared with a tall man, he is short, and when he is compared with a short man, he is tall.
4. Ask the children to go on stage and operate in order: from high to short.
Show five puppies and let the children arrange them from high to low or from short to high.
Summary: According to the order from short to high, first choose the front one, then find the shortest one from the rest, and then proceed with the rest in turn. The method from high to low is as above.
Children observe that from short to high: like climbing stairs. From high to short: like going down stairs.
Third, collective operation activities: mushroom dolls are taller than their height.
Teacher: Children, we have lined up roosters and puppies. Now let's line up these mushroom dolls. Please help them line up from high to low and then from short to high.
Fourthly, through the game of "Find a friend by height", we can further understand the relativity between height and height.
Teachers' self-evaluation:
In the activity, I learned how to compare the heights of objects, so that children can correctly distinguish the heights of objects. In the first part, I can design to let children look for objects that can be higher than their height, so that children can be more interested and active. The second part is to learn some relatively high and low methods. I will focus on teaching children to learn direct comparison, and children should be allowed to find out for themselves. In the activity, the teacher talked too much and asked too much of the children, which did not fully reflect the role of the teacher as a guide. Teachers need to further improve their language in future activities.
Activity evaluation:
1, there is little difference in the height of teaching AIDS, so the interference of size should be considered when preparing for the exam. 5. The operation of internal objects should be from easy to difficult.
2. The activity process should be more interesting.
When it comes to "who is taller than who, who is shorter than who", it needs to be said separately, and it is difficult for children to say.
Activity reflection:
This activity is based on the real life of children. In the whole process, the process is smooth, but there are also shortcomings: when children compare the heights of tall buildings at different levels, there is not enough discussion. Children don't understand the concept that objects need to stand upright on the same level only by instilling concepts in the teacher's concluding language. In future regional activities, we will continue to design special games for this problem, so that children can further experience and understand this concept through games.
2. Kindergarten middle class math courseware: crows drink water.
Activity objectives:
1. By measuring and comparing operation activities, the volume of the object is initially perceived.
2. Cultivate children's estimation ability and spatial perception reasoning ability.
3. Cultivate children's comparative judgment ability.
4. Develop children's logical thinking ability.
5. Cultivate the ability to observe, identify and bring to justice.
Activity preparation:
1, transparent small measuring cup (jelly shell), watercolor pen, recording paper. Everyone has it.
2. Operating materials:
① Black dates, broad beans, peanuts, cherry tomatoes and longan.
② Three physical drawings.
3. A bottle of green tea, two glasses of orange juice and green tea, a crow and two numbers flop.
Activity flow:
First, measure it.
(1) Introduction.
1, winter is coming. Crows have prepared a lot of food for winter. Let's have a look!
2. Let the children say their names and show the corresponding cards on the blackboard.
3. (Showing the measuring cup) Look, what is this? (Small measuring cup) Guess how many black dates do you need to fill this small measuring cup? (Children estimate, guess) How many beans do you need to put if necessary? Will it be as much?
Please measure your hands to see which food contains more and which food contains less. Think about why and record the results.
(2) Young children can freely choose two materials to measure and learn to record.
Teacher guidance:
1, count the same kind of grain and put it into a measuring cup.
2. Record in your own way.
3. boldly introduce your measurement results to your good friends.
(3) Summary:
Children show records and comment on measurement results.
Ask questions:
1. What grain did you put in the measuring cup? How much can you hold? The teacher recorded the results on the picture of the grain.
2. Who measured the peanuts? How did you measure it?
Conclusion: When measuring, the lines should be pressed tightly, and the results will be accurate.
Why can only one or two black dates and a dozen peanuts be put in the same large cup? (Guide children to infer the inverse relationship between food quantity and food size)
Summary: In the same measuring cup, the bigger the particles, the less the smaller the particles.
4. Let the children arrange the food pictures from big to small according to the results of reasoning.
Black dates, broad beans, peanuts
Second, the competition game: crows drink water
1) How can crows drink?
1, show the crow: Now, the crow is thirsty and wants to find water to drink. Wow, here is a bottle of green tea. The crow is so happy! (Showing a bottle of green tea) But the bottle is too high and there are too few drinks for crows. Children, help the crow! Guide children to find ways to throw food into the water to make the water surface rise.
2. Think about it. What food can make crows drink green tea the fastest? Why black dates? Yes, just a few grains can make the water level rise fastest. (Demonstration: Putting Jujube in a Bottle)
2) Compare the size of cherry tomatoes and longan.
1, the little crow drank green tea and felt a little hungry. It found two kinds of snacks, one is cherry tomato and the other is longan, but it can't tell who is older and who is younger. Who knows?
2. "Who will help crows distinguish the size of cherry tomatoes from longan?" Let the children find a way to provide two large cups of the same size.
We can't measure their size by cups, so can we compare cherry tomatoes and longan by drinking crow's water? We are divided into two pairs in the relay race, one is the cherry blossom team and the other is the longan team. You think the cherry tomatoes are big enough for crows to drink first, so you move the chair to the cherry tomatoes team. If you think longan is big, join the longan team.
4. Children's competition.
The teacher explained the rules: put one fruit in the bottle at a time, and then turn over a digital card of your team. The next child must clap his hands before he can start. Let's see which team has the least bottles of fruit.
5. Announce the comparison results of cherry tomatoes and longan and the winning group.
Who can say which group of children guessed right, and what is the bigger one? How do you know that?
Summary: It turns out that some things look big, but they are not necessarily big. This requires us to think more and compare in a smart way.
Activity reflection:
Mathematics can create a scene for children to participate in learning activities with hands, mouths, brains and multiple senses, stimulate children's interest in learning, arouse students' enthusiasm, give full play to students' physical and mental potential, save time, complete learning tasks efficiently, infiltrate ideological and moral education, cultivate good learning habits and psychological quality, and make intellectual quality and non-intellectual quality develop harmoniously. Guide students to "play" middle school, practice in "fun", increase their talents in "fun" and increase their courage in "competition". Improve learning efficiency and cultivate students' good study habits and organizational discipline.
3. Mathematics courseware for kindergarten middle class: 10.
Design background
In the usual math teaching activities, I found that the children in the class can't fully master the same number of hands and mouths. I want them to feel the process of abstracting concrete quantities into numbers, so I specially chose this teaching content.
moving target
1. Cultivate children's consistent number of hands and mouths, and review the number 1- 10.
2. Let children count the number of balls, draw the corresponding numbers in the picture below, and circle the correct number process, so that children can learn the corresponding numbers and feel the process of abstracting specific quantities into numbers.
3. Help children understand the practical meaning of numbers and cultivate the ability of abstract generalization.
4. Cultivate children's comparative judgment ability.
5. Develop children's logical thinking ability.
Important and difficult
Key point: let the children count their hands and mouths together.
Difficulty: Perceiving the process of abstracting concrete quantities into numbers.
Activities to be prepared
Digital cards, various commodities, food cards.
Activity process
First, import from clapping songs.
Review the digital baby 1- 10, and randomly select digital cards for children to read.
Second, in order
Let the children go to the blackboard and arrange the digital cards from 1 to 10.
Third, count.
Let the children count the number of items (pencils, butterflies, ducklings, etc.). ) and represented by numbers.
Fourth point
Colour the corresponding number of circles and circle the numbers.
1. Invite children to play at DuDu Niu's house. Dudu Niu took out many delicious things, such as corn, watermelon and candy.
2. Counting: Let the children reach the blackboard with the same number of points.
Dudu Niu forgot the number of these delicious foods. Please mark them with a circle and circle the numbers. Please count, color and circle the numbers on the blackboard.
Please turn the textbook to P 1 1 and the teacher will explain it in detail.
5. Teachers' itinerant guidance.
Teaching reflection
The teaching structure of this class is reasonable, and the children are very interested in it. Children count their hands and mouths consistently. Review the numbers 1- 10. Let children count the number of balls, draw the corresponding numbers, and circle the correct numbers in the picture below, so that children can learn the corresponding relationship of numbers and feel the process of abstracting specific quantities into numbers. Children are very active in doing problems. But one thing is that some children can't count yet, so they should strengthen their counting ability.
4. Mathematics courseware for kindergarten middle class: ordinal number and reciprocal.
Activity design background
There are many interesting maths in life. If children can gain experience from these daily lives and review and apply them to life, it will bring them not only knowledge, but also habits and fun. So in this math activity, I designed a math life experience that children usually come into contact with: ordinal number and reciprocal number, and learned this concept. I believe that when children take the elevator again, they will turn unintentional attention into intentional attention, which is more conducive to their learning and internalization of knowledge.
moving target
1. Emotion: Cultivate the consciousness of careful observation in daily life and experience the fun of learning mathematics.
2. Cognition: Perception of ordinal number and reciprocal law, knowing that the number after ordinal number is larger than before 1, and the number after reciprocal is smaller than before 1.
3. Skills: the ability to count and count down in the range of 10.
4. Cultivate children's comparative judgment ability.
5. Guide children to actively interact with materials and experience the fun of mathematics activities.
Teaching emphases and difficulties
The focus of this activity is to understand the internal laws of ordinal numbers and reciprocal numbers.
The difficulty of the activity lies in learning reciprocal and inverse numbers.
Activities to be prepared
1.1—12 sets of magnetic digital cards,1directional arrow.
2. Frog 10, some lotus leaves.
3. Two pictures of the same locomotive (difference: different license plates)
4. High-rise model 1, 1— 10, and paste number 1.
Activity process
Review the introduction of the activity first to stabilize the children's mood and get into the theme of the activity.
1. The teacher shows a set of digital cards and asks the children to read these numbers.
2. Simply compare the sizes of numbers, and initially perceive the size order of numbers. (Take advantage of the age gap between children and known siblings)
Second, perceive the law of ordinal number and reciprocal, and know what ordinal number is and what reciprocal is.
1. Show the train cards arranged in sequence, and guide children to observe the characteristics of the number sequence on the train car (the last number is larger than the previous one 1).
2. Swap the positions of two adjacent numbers on the train and guide children to observe and talk about what is wrong, why it is wrong and how to arrange it.
3. Teacher's summary: The method of arranging numbers according to the way that the last number is larger than the previous number 1 is called ordinal number.
4. Learn the concept of reciprocal in the same way.
Third, consolidate the concepts of ordinal number and reciprocal again.
1. The teacher introduces frogs in a magical tone, finds out the differences between frogs, guides children to find that some frogs have no numbers on their chests, and inspires children to fill in numbers according to the rules.
2. The frog wants to play hide-and-seek with the children, and guide the children to practice counting, counting backwards from any number.
3. By observing the building, guide the children to practice the number of continuous connections and the number of backward connections. For example, a * * who lives on the 5th floor wants to visit the * * home of 1 building, which floor should he take (countdown), and a * * who lives on 1 building wants to visit the * * home of the 5th floor, which floor should he take (ordinal number).
Fourth, the end part: expand children's thinking, guide children to recall where there are ordinal numbers and countdown in life, and enrich children's life experience.
Verb (abbreviation of verb) activity extension: please go home and ask your parents for information. What other uses do ordinal numbers and reciprocal numbers have? Next Monday, everyone will share with you.
Teaching reflection
At the beginning of the activity, the children didn't quite understand the sequence number. I use the quick-witted children in the class to stimulate everyone's thinking, focusing on observing the changes of the numbers on the train, because some children have been on the train and know that the train is divided into different carriages, including 1, 2 and 3 carriages, which speeds up the children's understanding of the serial numbers. After understanding the ordinal number, the child quickly accepted the countdown.
Personally, I think it is difficult to introduce it before the event begins. Later, I felt that a child can make use of his innate experience, like a child who has been on a train, and carrying out thematic activities in the early stage may make the course easier to carry out.
5. Kindergarten junior high school mathematics courseware: the conservation of 7
Activity objectives:
1, which can correctly count the numbers within 7 regardless of the size, shape and arrangement of objects.
2. Experience the interesting phenomenon of digital conservation.
3. Cultivate children's comparative judgment ability.
4. Stimulate children's interest in learning.
5. Develop children's logical thinking ability.
Activity preparation:
All kinds of physical cards, digital cards, food plates, touch boxes, smiling faces, music tapes, tape recorders, etc.
Activity flow:
First, introduce as "Sister Moon" to stimulate children's interest.
Second, open the password of "intellectual paradise" and review the numbers within 7.
Show the numbers 5, 7 and 6, and guide the children to express the corresponding numbers with actions.
Third, visit the "intellectual paradise" and feel the conservation of numbers within 7.
1, the teacher explained the demonstration.
2. Children can operate freely.
(1) Compare the number of physical cards between the two groups.
(2) Compare the number of two groups of objects on the plate.
(3) Compare the physical quantities in the two boxes.
3. Communicate the operation results.
(1) Show physical cards with different sizes, colors, shapes and arrangements to guide children to perceive the number conservation within 7.
Summary: Although the size, color, shape and arrangement position are different, the quantity is the same.
(2) verification.
4, the game "hide and seek".
(1) Introduce the gameplay and rules. (Emphasis on counting before comparing)
(2) Children's games.
Activity reflection:
1, this activity can feel the quantitative relationship of things from life and games, and let children experience the importance and interest of mathematics.
2. The whole teaching takes Sister Moon and children playing games as the main line, connecting all the links in series, which embodies the integrity and theme of mathematics teaching and is convenient for children to master the learning content.
3. Provide a large number of operational materials for children to explore independently, feel the conservation of numbers in pleasant operations, and make boring mathematical activities more interesting.
4. Disadvantages: Teachers try to explain clearly, so the language is a bit cumbersome, and they are afraid that children can't do well, and children have high interest in games, so children play more times.
