Design concept

This semester, we organically integrate mathematical thinking activities with kindergarten theme activities, and actively explore the game-based teaching strategy of entertaining and entertaining, so that children can actively think, learn happily and grow independently in activities. This activity is based on the theme activity "The more friends, the happier".

Teaching objectives

1. Perceive the characteristics of the shadow in the game and know that the shadow is the same as the physical appearance.

2. Learn to observe and compare carefully from top to bottom, from the whole to the tiny part, and judge and find out the shadow of the real thing on this basis.

3. Cultivate children's meticulous observation ability.

Teaching preparation

1. projector;

2. The child should have an operation card (the content on the operation card is progressive in difficulty) and a pen;

3. Two teacher's teaching model drawings, a paper stick, two slightly different plush bear toys, a red pen or chalk are pasted on both sides of the blackboard;

4. Preparation of shadow knowledge.

teaching process

1. Language arouses interest and leads to movie friends.

Teacher: Children, I really want to be friends with you. Would you like to be friends with me? (willing! ) Nice to make friends with you! I also brought a good friend of mine today. Where is my good friend? The teacher looked around a little. ) 1, 2,3 My good friend, please come out! At this time, the projection is bright, the teacher stands in the light and poses beautifully, and the wall immediately presents a shadow shape. Who is my good friend? Your shadow. ) right! My good friend is my shadow (as shown in figure 1).

comment

The teacher's interesting language and appropriate body language suddenly aroused the children's interest. When the movie friend suddenly appeared in front of the children, many children cried and were so excited. In the children's happy laughter, the activity is naturally introduced to the next link.

2. Play, say and perceive the relationship between shadows and objects.

(1) I feel different shapes and shadows when playing.

Teacher: Who wants to come up and invite their shadow friends? Please come up with four children at a time and repeat twice. )

After the children came up, the teacher read children's songs: 1, 2, 3, please come out! After reading "Please come out", turn on the projection lamp and a child's shadow appears on the wall. )

Teacher: Whose shadow friend is this? How did you know?

Yang: Because that shadow is the same as him. ...

After an exchange, the teacher summed up that the shadow friend's appearance is the same as that of a child; Children look different, and so do their shadow friends (Figure 2).

(2) Observe the subtle changes of shadows while playing.

Teacher: Who is here? (Two little bears. ) Look carefully! Where is Huang Xiong's shadow friend? Where is the shadow friend of White Bear? How did you know?

Children: the yellow bear is bigger and the white bear is smaller; The yellow bear has a small flower on its head, but there is no flower on the white bear's head. The white bear took a small cup, but the yellow bear didn't. ...

Teacher: Children's small eyes are really bright! When we are looking for movie friends, we can look at their overall shape first, and then look at their differences from top to bottom, so that you can find out who is whose movie friend (as shown in Figure 3).

comment

Games are children's favorite activities. Interesting shadow games fully arouse children's emotions, and children unconsciously learn the method of observation in happy games.

3. By observing, * * * is looking for a shadow friend.

(1) Teacher: Little friend, there is a little fox who can't find his shadow friend. What a hurry! Do you want to ask children for help? (willing! ) Look! A little fox and many similar shadows appeared. Please come and observe carefully.

(2) Wait a minute: "Who is Fox's movie friend?"

The teacher pointed to the shadow of children's unanimous disagreement and said, why not? (Different shape: forelegs backward ...) And take this shadow aside.

The teacher pointed to the agreed shadow of the two children (slightly different) and said, "The child said that this is his shadow friend, and this is also his shadow friend. First compare these two shadows (put them under the fox for children to compare and observe) and see if it is the fox's shadow friend. Contrast and look carefully from beginning to end. (After the child says "no") Q: Why not be the fox's friend?

Teacher: Oh! Fox has a long beard, but this shadow doesn't, so he is not his friend. Who is the fox's shadow friend? The children are pointing at each other. ) Yes, this is its shadow friend. (The teacher circled it with a pen. )

Teacher: It turns out that these two shadows are just slightly different in beards, which is really hard to find. It seems that it is necessary to observe carefully (Figure 4).

comment

Using the method of fox seeking help not only inspires children's strong inner pride, but also fully mobilizes their enthusiasm for learning and improves their concentration on observation. In order to help the fox find his shadow friend as soon as possible, the children soon used the observation method they had just learned.

4. Using observation, children can think independently.

(1) Teacher: Little Fox is so happy that the children helped him! But there are still many things here where they can't find their movie friends and want to ask children for help. Would you like to? (willing. )

(2) Put forward operation requirements.

Teacher: Look! Who can't find a shadow friend? Bicycles, ants, gourds, mice. Before looking for a shadow friend, the teacher made a request: please observe carefully from top to bottom, and look at them one by one, keep quiet and think for yourself, so as to find their shadow friend. After finding their shadow friends, draw their circle with a pen. Don't look for germanium Otherwise they won't be happy! Now take out your operation card and start!

(3) Children operate independently. Teachers should pay attention to observation, suggest that children think independently, and remind fast-moving children to pay attention to inspection. )

comment

When the children are still immersed in the enthusiasm of helping the little fox, the teacher provides them with an operation card, so that they can continue to exert their enthusiasm for helping others and operate and think independently by observation. Because children have the task of entrusting help, they are very serious when operating independently, and they can make full use of the existing observation methods to look around and think quietly.

(4) Evaluation communication

Teacher: Have you noticed, children? Let's tell them together!

Say the first one: Teacher: Come and tell it, which is its shadow friend? (1) Do you agree? (circle) Why not this? This one has no cushion, and the position of the bell is different from it. )

Say the second one: Teacher: Who is its movie friend? (2) What a careful observation! It is the shadow friend of the little ant. (Draw a circle) Why not? A hand is missing. )

Third: Teacher: Who is its shadow friend? (First and second) Now there are two views. Let's look at this first. Is it the same as the gourd doll? What is the difference? (The headscarf is different. This small place is different, and all the children found are great!

Fourth: Teacher: Who is its shadow friend? (There are many answers) Shall we look at the first one first? No, there are many tails and different ears. Draw a cross. ) Let's have a look at the second one, shall we? No, the beard is different. )

Which is the shadow friend of the little mouse? (the third one. )

Teacher: It's really hard to find the shadow friend of the mouse. You should find one of these three. But many children found out, you are great! In the future, we will put some more difficult ones in this area. Please find their shadow friends from the four shadows. You can have a try and see who is the cleverest.

(5) Revise the homework, and the teacher will make a comprehensive inspection.

Teacher: Do you think everything is all right, little friend? If you make a mistake, you can put a cross on the original one and find a new film friend. Suitable children can play games with their shadow friends.

comment

Adopt the way of children's collective evaluation, so that children can gradually learn to master the ability to judge their own operations independently in interaction. In interactive evaluation, children have a strong desire to express themselves, and especially want to be the first to tell you who their shadow friend is.

5. Extension: Children can freely play games with their own shadows.

The finished children can play shadow games freely under the light.

Chapter 2: Wonderful pomegranate receptacle

Teaching objectives

1. Review the counting method of pomegranate receptacle in closed arrangement.

2. Try to record the classification results by statistical methods, and be willing to introduce your own calculation results in concise language.

Teaching preparation

Have preliminary contact with the closed number; One sorting box, one statistical table and one pen; Pomegranate flower trays picked up by children, one for each group. "Pomegranate grows up quickly" operation diagram: a small pomegranate, a green pomegranate and a mature pomegranate are held as pomegranate flowers in turn.

teaching process

1. Review the counting method of closed arrangement.

(1) Count the petals of pomegranate flower Tori.

Teacher: Please ask each child to take a pomegranate receptacle from the plate and carefully count how many petals it has. How did you figure it out?

Summary: When counting petals, you should first determine a starting place, you can mark it, and then count one petal at a time, so that you can know where the counting can end without missing or repeating the counting.

(2) Check each other and re-determine the number of petals of pomegranate receptacle.

Summary: The number of pomegranate petals is different.

2. According to the number of petals of receptacle.

(1) Use the classic dialogue of the story "Three Butterflies" to illustrate the operation requirements. For example, "Room 4 said,' Please come in with four pomegranate flowers, not others. """No.5 said,' Please bring five pomegranate petals and nothing else.' "

Category box:

(2) Children's operation: Send five pomegranate flowers to the corresponding digital sorting boxes according to the number of petals in the receptacle.

(3) Show the children to each other, introduce their classification results, and talk about how many pomegranate flower trays were invited in Room 4, Room 5, Room 6 and Room 7 respectively.

3. Try to use statistical methods to record the classification results.

(1) Teachers and children discuss ways to establish recording.

Show me the statistics: let the children carefully observe what they see on the recording paper. Guess what they mean respectively?

(2) Children's operation, using dot symbols to record the number of pomegranate receptacles with different petals in the sorting box.

Teachers' itinerant guidance: pay attention to the methods and steps recorded by each child and understand the children's problem-solving strategies.

(3) Guide the children who finished first to observe their own recording paper and find out the most pomegranate flower holders and the least pomegranate flower holders.

4. The game "Pomegranate grows up quickly".

(1) Teachers and children establish the rules of the game: briefly state the number of pomegranate receptacles with different petals, and the pomegranate receptacles will grow up slowly after correct statement. (Children express the number of pomegranate receptacle recorded by themselves in complete language. For example, there are 65,438+0 5-petal pomegranate flower receptacles and 3 6-petal pomegranate flower receptacles ... After children tell stories correctly, they demonstrate the growth process of pomegranate with drawing teaching AIDS. )

(2) Communicate with each other and learn to express their calculation results in correct language.

(3) Play the game "Pomegranate grows fast", and children will tell it in turn, and show the process of pomegranate receptacle growing slowly through pulling.

Chapter three: outing

Design intent

We designed a mathematical game activity with children's spring outing as the main line. Through various forms of exploration, we guided children to truly perceive the concepts of quantity within 8 and sorting by quantity.

Teaching objectives

1. Correctly perceive the numbers within 8, and try to sort them by numbers.

2. Willing to participate in mathematical operations, able to observe and distinguish carefully while operating.

Teaching preparation

Preparation of teaching AIDS: two sets of physical cards, quantity1~ 8; Lamb headdress; Wisdom stick.

Preparation of learning tools: group 1: 6 sets of fruit cards, quantity1~ 8; The second group: 6 sets of ladybug sorting materials; The third group: 6 sets of digital solitaire materials.

teaching process

1. Teachers and students * * * enter with the music of "Outing".

Teacher: Do you know what season it is, children? The scenery in spring is beautiful. Shall we go for an outing today?

2. Perceive the number within 8 collectively and rank it.

(1) Teacher: Let's line up and start! Look, what is this? (There is a red, yellow and green flag on each side) Please look at the color code on your hand. Please stand behind the flag of the same color and start!

Please count the children. How many ideas are there on your card? (Guide children to observe carefully and feel the number of ideas on the card) Tell me which team you are on. (Line up in sequence)

(3) Please look at the ideas in your hands and line up in the order from less to more.

3. Set the stage and help the lamb.

(1) Teacher: Lamb, why are you crying?

Lamb: The wolf lined up for me to ask questions and said that if I can't do it, he would come and eat me. Can you help me?

(2) Show the operation sheet to help the lambs solve the problem collectively.

Teacher: Let's have a look. What fruit is there on it? How are they arranged? How many fruits are there behind a pineapple? Why? Let the children talk and arrange the fruits.

(3) Say goodbye to the lamb and move on.

4. Come to the smart house.

Teacher: Hey, there is a smart house. Let's go and have a look!

(1) Sister Wisdom receives children and introduces the names and requirements of group activities:

The first group: the fruit babies line up (first look at the place where the red flag is inserted in the box, and then line up the fruit babies according to the number). )

The second group: line up the ladybug babies (first look at some ideas on the ladybug, and then line up the ladybug babies in order from the five-pointed star. )

The third group: queuing digital baby (look at the position of the locomotive first, and then queue up in numerical order on the carriage. )

(2) Children's operation and exploration. (Teachers tour to guide and help children with weak abilities. )

(3) Teacher's summary: Today, the children are great. They played three kinds of queuing games in the smart room, and many children lined up in the order from less to more. Think about it, children. What else can we do? If you think of other good ways, please tell us again, ok?

(4) Wisdom elder sister gives gifts.

The outing is over.
