Activity flow:
(1) The beginning: The teacher takes the children to do the dance of "driving the train".
Teacher: "Little friend, magic kingdom has arrived. The king of magic kingdom gave me a treasure the other day. Look at this amazing dress I'm wearing. " This magic coat has a magic pocket with many magical things in it. Do you want to know what's in it?
(1), the teacher read a nursery rhyme: "There are many things in the magic pocket. Let me touch it first and see what it is? " He touched the square and asked, "What is this? (Fonka) The children are great! " A square has four sides, which are equal in length. Q: "What rectangular things have we seen in our daily life? (Inspiring the child to say) The child is great! Let's take a look at the pictures found by Teacher Luo.
(2) Read magic again: "Teacher Luo is going to do magic! Let's see what Teacher Luo has changed. The magic has changed into a rectangle. (Square is folded in half) Both sides of the rectangle are equal in length (touch). One side is long and the other side is "short". The child thought about it. What is the rectangle we see? Let's take a look at the pictures found by Teacher Luo.
(3) Read magic again: "Teacher Luo is going to do magic again! Look at what Teacher Luo changed this time. The magic has changed and become a triangle. (Square is folded in half) The triangle stands tall like a hill. Think about it, children. What is the triangle we see? Let's take a look at the pictures found by Teacher Luo.
Teacher: The children are great. They know so many graphic babies, and there are many interesting things in magic kingdom. Look, this is a magic wand, and it will produce many things. Let's see what changes it has. Magic (showing one of the pictures while talking) "Robot" Now, children, let's look for this robot. What graphic babies does it consist of? (like).
"Magic magic, wow, the magic wand is really powerful, and three pictures are drawn at once." The teacher "changed" several other pictures with his wand, and now he wants to invite children to look for them together.
Second, the game: the small animal looks for a mentor: "The wand is really powerful, and there will be small animals!" Children, who are you looking at? "Magic change! Change! Change! ("Change" three small animals) Teacher: "Hey! These three little animals seem unhappy. Let's ask them what happened. "
"Dogs, pigs and rabbits, what's wrong with you?"
(The little animal says:) "We can't find our home!" " "
"Children, let's help small animals find their homes! Will you? "
Yang: Yes.
Teacher: "Look, these are the houses of small animals. Now let's help small animals find their homes. "Teacher:" Small animals say that their houses are all shaped. Let's listen. Piglet said: Our house is square. Have children ever seen a square house? "Let the children raise the diamonds.
Teacher: "the children did a good job and helped the pig find a home." The dog said: Their house is triangular. Have children ever seen a triangular house? Let the children hold up the triangle card.
Teacher: "The puppy has found a home, too. Little Nutbrown hare said: Their house is round. Let's see where the round house is. " Let the children raise the round cards.
Teacher: "The children are really capable and helped the rabbit find a home." Teacher: "The children are so clever. They all help small animals find their homes. The dog, rabbit and pig are so happy. " (Send three kinds of small animals to the corresponding "houses" respectively)
(3) The last part: Let the children consolidate their understanding of the three geometric figures.
Teacher: "Little friend, today we met many baby pictures in magic kingdom. Who are they, children? " Show the cards of three geometric figures in turn and let the children name the figures.
Teacher: "There are many wonderful things in magic kingdom. The teacher will take you next time, ok? " Let's sing and go home! "Drive the train home.
Activity reflection:
The teaching goal of "interesting graphics" is to let children perceive circles, triangles and squares by comparison, and the basic characteristics of squares can distinguish three kinds of graphics. Middle-class children have a superficial concept of graphics. Although children at this stage can correctly understand these three kinds, they do not understand them from the characteristics of these shapes, but compare them with familiar objects in daily life. So I decided on the activity of "Interesting Graphics" to make children interested in graphics in game exploration, and to perceive the different characteristics of different graphics through observation, comparison, imagination and hands-on.
