Explore and discover the characteristics of spheres and cylinders.

Feel and experience the difference between plane graphics and three-dimensional graphics.

Be able to speak your mind boldly.

Activity preparation:

Some objects with different shapes and volumes, such as table tennis, cubic round paper, etc.

Pen, scissors, glue stick, rag, small basket.

Prepare an even number of papers of different sizes and shapes.

Activity flow:

First, explore

-guide children to explore, think and find things that can roll and put them in a small basket.

-Children can freely assemble for collection activities.

Second, discuss

-Children share their findings with each other and show that they can roll.

-Is it the same when guiding children to watch objects roll? What is the difference?

-Let children explore constantly to find the difference between a cylinder and a sphere, so as to initially perceive its characteristics.

Combine daily life and think about which ones are like cylinders and which ones are like spheres.

Third, move your little hands.

-Make cylinders of different sizes according to your own understanding and existing materials.

-Play around and feel the characteristics of the cylinder again.

Mathematical Activity Design-Hiding 3 and 8

Activity objectives:

1, know the number 8, and the relationship between perception number and quantity.

2, can correctly distinguish between 3 and 8.

3. Actively participate in activities.

Activity preparation:

1, digital card: 38 written on it.

2, all kinds of decorative paper and cards, sharp knives, glue.

Activity flow:

First, the meaning of "March 8".

1, the teacher shows the digital card for the children to read repeatedly, and the teacher leads the children to read. Let the children concentrate on learning the number 8. On the basis of reviewing 3 and studying 8, the teacher leads out that March 8 is Women's Day, which is related to the numbers we learned today.

2, 8 not only refers to the eighth, but also what does it mean? (8 toys, 8 kittens) The teacher uses some quantifiers as examples for children to imitate.

2. Hide 3 and 8.

1, since mom's holiday is coming, shall we bless mom with the two numbers we learned today?

2. Children can freely choose materials, decorate cards (choose decorations of 3 and 8), and hide 3 and 8 in the cards.

3. Let the children take the cards home and give them to their mothers, and give their blessings to their mothers.

Mathematical Activity Design ―― Understanding 6

Activity objectives:

1, the number of cognition 6

2. Cultivate children's observation.

Activity preparation:

1, 6 magnetic teaching aids, 6 radishes and 6 cabbages.

2. 6 snowflakes and digital cards per person 1-6.

3, tape recorders, tapes.

Activity flow:

First, integrate singing into activities

The children sang and performed to the music of the song "This Winter".

Teacher: This winter, children have delicious chestnuts, warm sweet potatoes, and children's favorite hot pot. It smells good. Today, I prepared delicious vegetables for the children. Do you know what vegetables they are?

Second, understanding 6

Show the magnetic teaching aid cabbage and radish in turn, and ask the children to have the same number of points in their hands and mouths, and correspond to each other one by one. Let the children say that the number of cabbage and radish is 6.

Teacher: Six cabbages and six radishes can all be represented by "6". Show the word card "6" What does it look like for children to read "6"? Stimulate children's imagination and say "6" like whistling "beep".

Third, children's operation

The teacher beat the drums several times to make the children clap their hands.

Look at the numbers and put snowflakes. The teacher shows the digital card, the children recognize the digital card, and the children recognize the numbers and put out the corresponding number of snowflakes.

Fourth, look for exploration.

The teacher asked the children to find six toys or other items in the classroom and tell the total.

Activity expansion:

Lead the children to the yard to continue looking for 6 items and toys.

Middle School Mathematics Activity —— Activity Design

I. Name of the activity: "Looking for good friends"

Second, the activity objectives:

Stimulate children's interest in learning adjacency numbers.

Further develop children's ability to analyze problems.

Help children understand the relationship between adjacent numbers greater than 1 or less than 1, and can tell the adjacent numbers of 2 and 3.

Third, the activity preparation:

Teaching aid for fish activities: 1 red carp, 2 white carp, 3 golden carp and 4 green carp.

Some 1 digital cards-4.

The music of "Looking for Friends".

Fourth, the activity process:

Beginning part:

Let the children discuss how they were born.

Basic parts:

Let children observe and think: Do you know how small animals are born?

-guess, are there any animals born by dad?

The teacher demonstrated the story once.

-Let me ask you a question, why can the father hippocampus give birth to the baby hippocampus?

-How did the little seahorse get out of dad's body? Learn some basic knowledge about hippocampus.

-What's the breeding method of seahorses? Understand the structure of hippocampus.

At the end:

Please read the story again, so that children can read books and other materials freely and exchange their findings with each other.

■ Activity extension: Let children know more about small animals in the water, and let them raise a small fish or turtle, tadpole, etc. At home, let them observe the growth process of small animals.

Small class science teaching plan in kindergarten: small thermometer

Useful learning experience:

Understand the use of thermometer and thermometer, and master the use of thermometer initially.

Preparation: thermometer

Activities and guidelines:

1, the body temperature of healthy people is around 37 degrees, and it will change when you are sick. Do you know how to know whether the temperature is normal?

You can measure a person's temperature with a thermometer.

3. Take out the thermometer and tell the child that it is a thermometer. Please observe the shape and characteristics of the thermometer carefully.

When you need to measure your temperature, put the thermometer under your arm (also in your mouth). Keep the temperature of the thermometer below 35 degrees, then hold the bright end and insert the metal-free round head under your arm.

5. The teacher demonstrated to the children and focused on the points that need attention.

6. Ask individual children to perform.

7. We will know how to measure our body temperature later.

Small Class Science Teaching Plan in Kindergarten ―― Wonderful Underwater World

Useful learning experience:

Know the common and frequently eaten aquatic products and name them.

Prepare:

Show the children around the aquarium, palace or underwater world. If there is no such place in this area, you can take your children to the aquatic products market.

Activities and guidelines:

1. Take the children to visit the Aquarium Palace or the aquatic products market (if the conditions are not met, you can find some videos or pictures).

2. Introduce the children while watching and tell them the names of these aquatic products, such as fish, shrimp, crab and kelp.

3. Let the children observe carefully and tell the shapes and simple features of these aquatic products.

4. Summary: There are many kinds of aquatic products, including fish, shrimp, crab and kelp. They all grow in the sea or lakes, and these aquatic products can be processed into delicious food. They are our good friends.

Suggestion:

You can choose a place to visit in advance. Please ask the narrator to explain it to the children.
