As an excellent people's teacher, careful design of teaching plans is conducive to the improvement of teaching level and the development of teaching and research activities. Then the question is coming, how to write the lesson plan? The following is my teaching plan for cutting cakes in kindergarten. Welcome to read the collection.

Kindergarten teaching plan cut cake 1 activity goal:

1. Guide children to learn to divide an object into two or four equal parts.

2. Explore the methods of bisection of various objects to stimulate children's interest in bisection.

3. Experience the diversity of cake cutting methods and the pleasure of success in solving problems.

Activity preparation:

1. Teaching aid: 4 dolls.

2. Learning tools: According to the group preparation, several round, square and rectangular cakes made of oil sludge (you can prepare them with your children the day before). A mason's knife, several square, rectangular and round pieces of paper with cake patterns, several paper clips and a pair of scissors.

Activity flow:

(1) Introducing the theme in the form of magic.

1. Teacher: Today, a clown came to our class. Now, would you please ask the clown to perform magic tricks for us?

2. Teacher: The clown wants to share the cake with the doll. Please watch carefully.

(2) Divide the cake for the birthday doll.

1. The teacher showed a cake and four dolls. Please tell the children how many dolls have birthdays.

Teacher: Four dolls celebrate their birthdays and share a cake. How do clowns share it?

Teacher: Are the four cakes shared by the clown the same? How to prove that four copies are the same?

2. Peer-to-peer communication of their own proof methods.

(3) Teachers show round, square and rectangular cakes, and ask children to help the clown divide the cake into two parts and four parts.

1. The teacher shows cakes of different shapes. The teacher asked the children to take part in the activities.

Teacher: Please help the clown to distribute cakes of different shapes to four dolls. Each doll is the same size. After dividing, try to prove that your four parts are the same size.

Children divide cakes in groups.

4. Encourage children to try to divide cakes of various shapes into equal parts.

Compare whether the segmented parts are the same size, which is larger than the original picture and each segmented part? Which is smaller?

(4) communicate and share, and perceive the relationship between the part and the whole.

1. Ask individual children to demonstrate how to share the cake equally and introduce the operation method.

2.* * * and verify whether it is divided into four equal parts and whether the four parts are the same size are the same.

Teacher: How do you know that four copies are the same size? Which is bigger 1 serving or the whole cake? Why?

Activity expansion:

1. Regional activity: Put cakes of various shapes in the math activity area, and let children explore many different methods of bisecting and quartering rectangles, and divide cakes of the same shape into four parts in different ways.

2. Family education: Please ask parents to provide equal opportunities for their children to practice at home.

Activity objectives:

1. Actively explore, try to divide the circle, square and rectangle into two parts and four parts, and perceive the relationship between the parts and the whole.

2. Try to find out the bisection and quartering of various graphics by talking, folding and cutting.

3. Children use equal knowledge to solve problems in life and experience the joy of success.

Activity preparation:

1. Material paper: round, heart-shaped, tree-shaped, square and rectangle.

2. Courseware production: A New Biography of Stupid Bear, a diagram of the relationship between parts and the whole.

Activity flow:

First, the initial contact bisection.

1. Settings.

A pair of lovely twins live in the forest. (Operation) They are Xiaohe and Xiaohong. Today is their brother's birthday. Look! They received many gifts (operations) (oranges, drinks, cakes, ribbons). Xiaohong and Xiaohei argued, "I want it." "I want it." Mom said, "honey, don't worry." There are requirements for wanting gifts. You have to divide these things into two parts, so there are as many as two parts. " Two little bears are in trouble and don't know what to do. Let's discuss with the children next to us and help their brother.

2. Operation demonstration.

Oranges (operation)

Teacher: If you were asked to help, how would you divide these oranges? Please come up and try it.

The teacher concluded: We can divide these oranges into two equal parts by counting.

3. drinks.

Teacher: How do we divide the drinks?

Look! Here are two identical cups. Now, there are as many drinks in two cups.

4. Cake

Teacher: How to divide the cake? I'll let the children share one.

5. Ribbon

Teacher: Is there any good way to divide ribbons? Please try it. What should I do first? Just cut it like this? )

The teacher concluded: It turned out that a ribbon found the center line, cut it from the middle, and the two sections overlapped to divide the object into two identical parts. This is equal share, and the equal share is smaller than the whole.

Just now, the children divided these gifts into two identical parts and two parts by counting, folding, cutting, pouring, measuring and cutting everything, which also made the bear get the gift smoothly. They are so happy! Thank you, children!

2. Divide the circle, heart, tree, square and rectangle into two parts and four parts in different ways.

The first level is a breakthrough. The teacher explained the operation requirements and explained.

(Operation) Teacher: "What a big gift box. If the gift-giving guests want to test twins and get this gift, we have to go through three levels. Let's look at the first level first. Please divide these materials into two parts. The twin brothers are confused again. How do we divide these figures into two halves?

The teacher concluded: We can fold diagonally, diagonally, and be careful when folding, so that the two faces overlap.

Teacher: Just now, some children split the rectangle in two in different ways. Please come up and introduce your good method (operation).

The teacher concluded: Just now, we used our brains to try to divide these shapes into two parts with the same size. You successfully passed the first level, which is really good! Are we confident to help the twins get into the second level?

(3) the second level

Teacher: "the second level, but it's a bit difficult." Please divide the rectangle into two halves in three ways. Look, there are three rectangles. We will divide three rectangles into two halves in three different ways. (Holding the surgical card) We can fold it first and then cut it. Pay attention to safety when cutting. Children who finish first will see if they can overlap.

Teacher: Come back to your positions and talk about your good methods.

The teacher concluded: There are three ways to divide a rectangle equally. How did the children find that the cut part is better than the original one just now? These two pieces are exactly the same as the original.

(4) the third level

Teacher: With the help of children, the twin brothers finally reached the third level. Do you have the confidence to help them win the final victory? Divide the chart into four parts. Just now, we learned the dichotomy. There are circles, squares and rectangles. Would you like to help us divide these figures into four equal parts? Please select a graphic to try.

Ask individual children to talk about their own methods.

Summary: these divide the graph into four equal parts, that is, four equal parts.

(5) Conclusion.

The third level is also successful. You are really something. How happy you are to see two little bears receive presents!

Activity expansion:

1. Divide other shapes into equal parts in the math area.

2. Help some objects or liquids divide equally.
