Teaching plan of kindergarten mathematics comparison 1 activity name: comparison.
Activity goal: 1. Learn to measure the weight of objects with scales.
2. Be aware that the size of an object is not necessarily heavy, and the size of an object is not necessarily light.
Activity preparation: cartons, scales, building blocks, marbles, plastic balls, rubber balls, iron balls and other items.
Activity flow: 1. Let the children compare the weight of the object with their existing experience among many things.
-"Are these objects the same weight?" Encourage children to weigh by hand.
2. Help children find that the weight of objects is relative.
Please compare plastic balls with rubber balls, and then compare rubber balls with iron balls. Help children to establish a relative concept: the ball is heavier than the plastic ball; Ball and iron ball are lighter than ball.
3, inspire children to use their brains: some objects have little difference in weight, and it is difficult to pick them out by hand. What should we do?
Show two items of similar weight: "How do I know which of these two things is heavier and which is lighter?" Inspire children to speak freely and affirm their imagination and speech. )
4. Introduce the measuring tool-balance.
-Children try to measure the weight of an object with a balance and introduce the use of the balance. The sight must be centered and handled with care.
5. "Guess which of these two things is lighter and which is heavier?" Let children measure and verify with scales.
6. Choose items with the same volume and different textures for weight comparison, and understand that the large volume is not heavy, and the small volume is not necessarily light.
-Show two boxes of different sizes, let the children guess which is lighter and which is heavier, and then verify it with the balance. Put the cotton in the big box and the iron in the small box.
7. Ask children to give examples to illustrate what other examples are there in life?
Activity suggestion: put a balance in the class to guide children to become interested in the balance and explore the function of this object.
Extension: 1. Take the children indoors or outdoors to find two comparable objects for light and heavy comparison.
2. Ask parents and children to read children's books and play intellectual games: compare who is lighter and who is heavier.
Kindergarten Mathematics Relative Weight Teaching Plan 2 Activity Target
1. Let children learn more important methods through activities and learn to record initially.

Activity process
First, the teacher shows two eggshell dolls.
1. Teacher: Today, the teacher brought two little dolls to the children. What are they made of? (Eggs)
These two little dolls, one is made of eggs and the other is made of eggshells.
Please try to tell which one is an egg. "
Ask a child to stand up and tell the way.
Summary: Just now this method is called acupuncturing.
Second, show all kinds of toys and materials, let the children group and compare the weights in various ways.
1. Teacher: What method do you use to distinguish its severity?
2. Inspire children to say: connect objects end to end, lift them, hug them and compare their weights.
Third, the teacher shows the homemade scales.
1. Teacher: If you want to compare the weights of objects accurately, you can also use the method of weighing.
2. The teacher put the wooden beads at one end of the balance and the glass beads at the other end, so that the children can observe which side is heavy and which side is light.
3. Summary: Glass beads are heavy, wooden beads are light, heavy ones hang down, and light ones tilt up.
(Learning vocabulary: vertical and vertical)
Fourth, group computing activities-compare the weights of two objects.
1. Let the children take two things from the basket.
2. Let the children communicate the operation results with their peers.
The teacher shows three kinds of fruits.
1. Teacher: Teacher, here are three kinds of fruits, apples, pears and oranges, which is heavier?
2. Let a child use the teacher's balance to make a conclusion, and the teacher will demonstrate the result on the recording paper on the blackboard.
(Learning words: neither light nor heavy)
Sixth, children's second group of operation activities-compare the weight of three objects.

Activity flow:
1, the teacher showed two eggshell dolls: "Today, the teacher brought two little dolls to the children. What are they made of? " These two little dolls, one is made of eggs and the other is made of eggshells. Let the children find a way to tell which is the egg. "Please ask a child to come forward and tell the way. The teacher concluded: "Just now this method is called nudge nudge. "
2. Show all kinds of toys and materials, let the children group and compare their weights in various ways. Teacher: "How can you tell its weight?" Inspire children to say: take one end, mention it, hug it and compare the weight of the object.
The teacher took out a self-made balance and said, "If you want to compare the weight of objects accurately, you can also use the method of weighing." The teacher put the wooden beads at one end of the balance and the glass beads at the other end, so that the children could observe which side was heavy and which side was light. The teacher summed up: "Glass beads are heavy, wooden beads are light, heavy ones hang down, and light ones tilt up." (Learning vocabulary: vertical and vertical)

(2) Ask children to communicate the operation results with their peers.
5. The teacher shows three kinds of fruits: "Teacher, here are three kinds of fruits, apples, pears and oranges. Who is heavy and who is light? " Ask a kindergarten teacher's balance that after * * * draws a conclusion, the teacher demonstrates the result on the recording paper on the blackboard. (Learning words: neither light nor heavy) 6. Children's second group of operation activities-compare the weights of three objects.
(1) Let the children take three things from the small basket.
(2) Let the children record the operation results.
Activity reflection:
This activity comes from children's life and embodies the educational concept of respecting children's development and making children the initiative of learning and the main body of activities. At the beginning of the activity, the teacher introduced the activity in the form of games and chose the life scene of seesaw, which made the children interested in comparison in a relaxed and natural atmosphere. Then, the teacher guides the children to compare familiar objects in daily life. They ask questions from different angles by comparing different objects in different forms, which stimulates children's positive thinking and exerts their creativity. The whole activity is well-designed and closely linked. Children compare the weight of objects in the process of hands-on operation, brain thinking and language expression, and experience the fun of comparing the weight of objects in various ways.
Teaching plan 4 Activity design background of kindergarten mathematics comparison
With the growth of age, children in large classes are more and more interested in activities such as hands-on operation, simple comparison, classification, estimation and judgment, and are interested in the weight and size of different objects in their surrounding lives, and like to try to compare. In view of this feature, therefore, I designed a mathematical activity: compare weights, let children learn to compare the weight of objects through natural estimation, judge the weight of objects through visual inspection, hand holding and other methods, and develop children's perception and judgment ability.
moving target
1. Learn to compare the weight of objects by natural estimation methods such as weighing, trial and comparison.
2. Be able to correctly judge and express the weight of an object in fluent and complete language.
3. Experience the pleasure and success of comparing the weight of objects in various ways.
4. Cultivate children's interest in calculation and the accuracy and agility of thinking through various sensory training.
5. Cultivate children's habit of speaking while operating.
Teaching emphases and difficulties
1, learn the method of estimating and comparing the weight of objects naturally.
2, can correctly judge and use fluent and complete language to express the weight of the object.
Activities to be prepared
1. one plush toy for bear, rabbit and duckling; Seesaw; Computer courseware.
2. Everyone has a study basket, which contains two wooden building blocks of different sizes, two glass balls of the same size, a cotton ball, a small magnet, two identical cups and a proper amount of water.
Activity process
1. scene import.
Use seesaws and plush toys to create an animal park and demonstrate it. Inspire children to compare the weight of small animals through visual judgment, and tell who is the heaviest, the lightest and the neither heavy nor light among several small animals. Judging the severity by visual inspection is vivid, natural and childlike, which not only successfully guides the activities, but also stimulates the children's interest in learning.
2. Explore all kinds of materials.
Guide children to make full use of learning tools to operate, feel the weight of different objects and learn to compare the weight of objects.
(1) Choose two items at random, and feel that some items are light and some items are heavy. Put it in your hand and say how you feel. Some things are heavy and some are light. )
(2) Comparing wooden building blocks of different sizes, we know that big building blocks are heavy and small building blocks are light.
(3) Compare the weight of glass balls with the same size.
(4) It is found that cotton balls of the same size are light and glass balls are heavy.
(5) Comparing the big cotton ball with the small magnet, the child feels strangely that the big cotton ball is light and the small magnet is heavy.
3. Application in life.
Provide children with two identical cups to stimulate their learning initiative and creative thinking.
(1) Compare and judge the weights of the two cups first.
(2) Guide children to explore freely through various ways of thinking and experience changing the weight of objects.
Teachers guide children to compare the weight of two identical cups in life, introduce activities into life and guide children to learn in life. Comparatively speaking, children explore how to change two cups with the same weight into cups with different weights, which stimulates the creativity of children's thinking, and the cultivation of thinking quality is an indispensable and important goal of mathematics activities in large classes.
Through the previous activities, children have a perceptual understanding of weight. In order to further enhance their experience and challenge their thinking, the comparison of different watermelons and pears, candles lit with the same weight, balls in scales and melted ice have created good conditions for children to explore and compare, further activating their thinking and expanding their thinking in the debate.
