Teaching plan of "comparing height" in mathematics for middle class in kindergarten [3 pieces]
# Lesson Plan # Introduction By visually comparing heights, we can know what is high and what is short, and perceive the relativity of heights. I have compiled three teaching plans of "Comparing Height" in kindergarten middle class, hoping to help you! one

Activity target 1. Experience the fun of participating in math activities in comparison activities.

2. Further cultivate children's comparative observation ability and thinking flexibility.

3. Learn to distinguish between height and height, master simple methods to distinguish between height and height, and initially understand the relativity between height and height.

Activity preparation courseware: math card -3-3 comparative concept, 3-4 comparative concept, 3-5 comparative concept.

Activity process

First, import

The teacher organizes children to play opposite games to stimulate interest.

The teacher said "high", the children said "short" and squatted down at the same time;

The teacher said "short", the children said "high" and stood up at the same time.

Second, expand

1. Learn to distinguish between height and height.

(1) Compared with peers,

Ask the children to compare with their partners and say: Who is taller and who loves? Who is as tall as who?

(2) Math Card: 3-3 Comparison Concept

Compare the two buildings, which one is taller? Which one is short?

Two gift boxes, which is taller? Which one is short?

Which of the two chefs is taller? Which one is short?

Two ladders, which is taller? Which one is short?

2. Compare the heights of two objects and master the methods of comparison.

(1) Please invite two children, one tall and one short. The short one stands on the stool and the tall one stands on the ground.

Cover their nakedness with a baffle and let the children judge who is tall and who is short.

(2) A giraffe was lying on the ground and a kitten climbed to the top of the tree. The kitten lowered its head and said to the giraffe, "Look! I am taller than you. "

Question: Is the kitten right? Why?

(3) Explain the correct method of comparing heights.

Summary: When you grow taller, you should stand at the same height.

3. Perceive the relativity of height. (Teachers should pay attention to express clearly)

(1) Math Card: 3-4 Comparative Concepts

Compared with these three buildings:

Building A is taller than building B, and building B is shorter than building A. ..

Building a is shorter than building c, and building c is taller than building a. ..

Compared with three trees:

Guide the children to say: b is higher than c, c is higher than b, and b is shorter than C.

(3) Discussion: Why is B high for the first time? What about the second time B became shorter?

(4) Summary: Whether a person or an object is tall or short depends on who it is compared with.

4. Four people in the group lined up for infiltration ranking. Let the children tell who is taller and shorter than who.

Further perceive the relativity of height and try to queue from short to high.

5. Music game "Find friends"

The teacher played a cheerful children's dance music and the children clapped their hands according to the festival. When they find friends, they shake hands, bow and compare their heights.

After the children found friends, the music stopped and the children told the results of their comparison. Games are repeated, and friends keep communicating.

Third, the end.

Activity evaluation, praise children who actively participate in comparison and careful observation.

two

Design background Because all the students in this class are about four years old, they don't pay enough attention, so I use velvet teaching AIDS to enhance students' attention, attract students and improve their interest in learning.

moving target

1, gradually cultivate children's observation, comparative ability and thinking agility.

2. Learn to distinguish the height and tell the comparison results.

Important and difficult

1, through the visual comparison of height, know what is high and what is short, and perceive the relativity of height.

2. By learning the order of heights, you can find out other objects that are higher (shorter) than something in a group of objects.

Activities to be prepared

1, velvet teaching aid: two trees with different heights; A giraffe, a dog and a duckling; Houses of different heights

2. Teaching AIDS: sticks, building blocks, plastic bottles, cups, etc. of different heights.

Activity process

First of all, visually compare the heights of objects and learn to distinguish between high and low.

1. Show two kinds of trees with different heights to guide children to observe. See which of the two trees is taller and which is shorter.

2. Show two houses with different heights and guide the children to compare.

3. Compare the height of animals. The teacher showed three kinds of animals with different heights: giraffe, dog and duckling. Ask the students to find the animals and the shortest animals.

Second, the height comparison between children and children's group activities

1. Let two children, one tall and one short, come up and see who is taller than who. Who is shorter than who?

Please invite a child of medium height to come up again. All three children are shorter than their height. See who she is taller than. Who is she shorter than?

3. Help animals find homes. Let children help animals find homes according to their height: tall animals enter tall houses and short animals enter short houses.

III. Operation and Practice

1, compare the height of the bottle. Ask the children to compare the three plastic bottles on the table and point out the shortest bottle.

2. Look at the height. Guide children to look for objects with different heights in the activity room, and let them tell the results of the search, such as "the teacher is tall, the children are short", "the table is high, the chair is short", "the cupboard is high, the table is short" and "the children are tall and the dolls are short."

Fourth, practical exercises-sorted by height

1, each child uses the following calculation materials to rank the height:

(1) Sort by bottle height; (2) Stacking stairs from low to high according to building blocks;

(3) classifying according to the height of cups; (4) Sort by stick height.

2. Discussion: Ask individual children to bring the arranged toys to the podium. What toys are these? How many did you count? The teacher pointed to one of them and asked, what are those taller toys? What are the toys shorter than it?

Verb (abbreviation for verb) outdoor activities

It is higher for children to look for objects outdoors.

"Today, we learned how to compare heights. Now let's line up from short to high and see if there is anything outside that can compare with height. "

three

I. Activity objectives:

1, learn to compare heights in the right way and perceive the heights of two or three objects.

2. Understand the relative relationship between "high" and "short".

3. Be able to actively participate in activities and be willing to share happiness with peers.

Second, the activity preparation

1. Environmental preparation: put a small arch at the entrance.

2, children's preparation: use three trees of different heights to draw practice paper.

Third, the guiding points

1, activity focus: how to perceive height and learn height.

2. Activity difficulty: Understand the relative relationship between height and height.

3. Guiding point: Through visual inspection and comparison, guide children to compare their height, and initially understand that comparing height requires reference objects, which is relative.

Fourth, the activity process

1, preliminary perception of height.

(1) Children are allowed in. (The children walk under the small arch at the entrance in turn)

(2) Ask: "Why do some people have to bend over when walking, and some people don't need to bend over when walking?" Children are free to discuss and speak.

(3) Teacher's summary: Some children are tall and have to bend over to cross. Some are short and don't need to bend over.

2. Compare the height, and initially understand the correct method of comparing the height.

(1) Both teachers and children are taller than children.

The teacher stands at attention on the ground and the children stand at attention on the ground. Let's compare who is tall and who is short.

The teacher is taller than the child and the child is shorter than the teacher.

(2) The proportion of children's height.

First, the two children grow at different heights, and then at the same height. Guide children to discuss: which method is more correct than height?

Summary: The correct way to compare height and height is to compare them on the same horizontal line.

3, preliminary understanding of the relative relationship between "high" and "low"

(1) Please compare two children, one is tall and the other is short, and then compare the tall child with the teacher, or compare the short child with the short child. Let children understand that height is relative.

(2) Let the three children line up from high to short, and tell who is tall and who is short.

(3) Children's exercise: Let children draw three trees with different heights in different colors and sort them from high to short and from short to high. Teachers' itinerant guidance and evaluation. ?

(4) Game: Compare with friends.

Children clap their hands and recite nursery rhymes: "Find, find, find, find a friend, find a good friend, stand at attention and compare whether I am tall or short." The game is repeated 2~3 times.

Every time a child finds a different friend, talk about the result of growing taller. Say it out loud; "I am as tall as xx", "I am taller than xx, and xx is shorter than me" and so on.

4. Extended activities:

In the activity room, encourage children to look for any objects or children taller than themselves. And it can be expressed in words, such as: I am taller than the painting, and the painting is shorter than me; I compare with the railing, I am tall, the railing is short and so on. Remind children to stand on the same plane and compare.

Verb (abbreviation for verb) evaluation elements

Whether to master the method of height and find the relativity between height and height.

Suggestions on the activity of intransitive verbs

1. Going home is taller than mom and dad respectively. If children are taller than their parents combined, how should they be compared? Tell everyone the method of comparison.
