The design intention of excellent math teaching plan 1 for kindergarten middle class;
Middle-class children have a superficial concept of geometry. At this stage, children can correctly understand circles, triangles and squares, but they are not recognized from the characteristics of these shapes, but compared with familiar objects in daily life. So I designed the activity "Graphic Kingdom" 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.
Focus of activities:
Know the semicircle.
Little activity:
Use geometric figures to spell out figures.
Activity objectives:
1, consolidate circles, squares, rectangles, triangles, and recognize semicircles.
2. Stimulate children's desire to explore.
3. Spell out figures with different geometric figures.
Activity preparation:
PPT, geometry
Activity flow:
(a) at the beginning:
"Today, the teacher found an envelope. Let me see what it says. "
The teacher read the letter, "dear children, I am the king of the graphics kingdom." I invite you to be the king of our graphic kingdom. I invite you to join our graphic kingdom. There are many beautiful figures here. Would you like to come?
The teacher let the children sit in their seats, and the teacher sat in the front and drove the train to the graphic kingdom.
"Children, let's drive the train to the graphic kingdom." The teacher played the music "Train Fast".
Second, the game: touch the "magic box".
Teacher: "children, the kingdom of graphics has arrived." There is a wonderful box in the graphic kingdom. Look, this is the magic box. (showing the box) Do you want to know what the secret is? Ok, let's see what interesting things this box will change for children.
The teacher reads children's songs: "There are many things in the magic box. Let me touch it first and see what it is? "
Touch the squares and ask, "What shapes are they? (Square) "
Q: What else is square in daily life? (Inspire children to say)
Read the children's song again: "There are many things in the magic box, please let the children touch them."
When children touch it, they are asked to tell what other such things are in their lives. The game is repeated.
The teacher concluded: Some things in the magic box are round, some are triangular and some are square.
How do you know it is a triangle/square/circle/trapezoid?
⑤ Teacher's summary: Round: Round, without horns, rolling around can really run; Triangle: Trilateral triangle, standing like a mountain;
Square: the four sides are equal in length, the four corners are equal in size, and the squareness is good.
Trapezoid: four sides and four corners. The top and bottom are flat and the sides are inclined. The four corners are different in size, just like a slide.
Third, show a semicircle.
"Son, have a look. There are many watermelons in the graphic kingdom. What shape is watermelon? If the teacher cuts them off, what shape will they become? "
"This is a semicircle. The teacher cut it horizontally just now. Now the teacher has to cut it vertically to see if it has become a semicircle. "
"What is the semicircle in life?"
"Children, let's see what graphics the teacher can spell with a windmill."
Show PPT, windmill turn.
Fourth, the game: small animals find homes.
"Kid, there are many interesting things in the graphics kingdom. You see, this is a magic wand, and it will produce many things. Change! Change! Change! Hey! What happened to the wand? (Four kinds of small animals transform) What kind of animal do you think he is, kid?
"Ah! These three little animals seem to be crying. Let's ask them what happened. " Puppy, what's the matter? "
(The teacher imitates the voice of a small animal) "We can't find our home, and we can't see our mother!"
"Children, let's help small animals find their homes! Will you? "
Teacher: "Look, these are the houses of small animals. Now let's help small animals find their homes. "
The teacher asked a child to spell out the house on the blackboard.
The dog said that the main body of the house is square, the roof is triangular, the door is rectangular, and the windows are semicircular and round. "
(5) Game: Who has the greatest skill?
The teacher "changed" a picture composed of circles, triangles, squares and semicircles with a magic wand. Ask the children to find the baby figures and count how many there are in each figure.
Teacher: "children, there are many interesting things in the graphic kingdom." You see, this is a magic wand, and it will produce many things. " Change! Change! Change! Hey! What happened to the wand? (Showing one of the pictures while talking) It turned out to be a beautiful picture. Now, children, let's find out which shapes this picture is made of and count how many there are in each shape.
(2) Teachers use magic wand to "change" other pictures in turn, so that children can find out all kinds of pictures respectively and count how many there are in each picture.
Six, the operation practice
"Children, please go back to your seats now. Children in each group have to spell out different patterns. "
Conclusion: Let students consolidate their understanding of four kinds of geometric figures.
Teacher: "children, today we met many graphic babies in the graphic kingdom." Who are they, children? " Let the children name the picture.
Teacher: "There are many wonderful things in the graphic kingdom. The teacher will take you next time, ok? "
The goal of the excellent math teaching plan "Graphic Kingdom" in Class Two of Kindergarten Junior Middle School;
1, find out their arrangement rules and sort them by graphic comparison operation.
2. Cultivate children's ability of observation, comparison, preliminary judgment and reasoning.
Activity preparation:
Teaching AIDS: wall chart (graphic kingdom), several pieces of paper with various spelling rules.
Learning tools: each person has a blank sheet of paper.
Activity flow:
First, to attract children's interest and lead to topics
1. Teacher: Children. Today, the teacher took the children to play in the graphic kingdom. There are many secrets in the graphic kingdom. The teacher knows that the children in our big class (3) are the cleverest and will definitely break through. Are you willing to accept the challenge? Then let's go! !
2. Before coming to the gate of the graphic kingdom, teacher: Let's open the gate of the kingdom first. What do we see? (three steps)
Teacher: Every floor has a little secret. If the child can't find it, he can't pass. Let's go to the first floor first.
Show the first floor:
(1) What do you see? Yes, there are so many graphic babies. They lined up neatly to welcome our children. )
(2) Please read it carefully. How are the babies arranged in this row of images? Did you find any little secrets?
(3) The teacher's summary reveals that there are certain rules in the arrangement of these graphic babies. Every time it is a group of three, and the group of three repeats in this order. Then we can say that it is regular. (Children follow)
(4) think about it: what should I do next?
Find a pattern
Teacher: Just now, all the children discovered so many little secrets with their big bright eyes and passed the first level. Do you want to continue?
Show the second floor:
(1) What pattern did you find? If you can't find it, you can let your child read it. )
(2) How many people are there in a group?
(3) Teacher's summary: These graphic babies are repeated in the order of red, yellow and blue.
(4) think about it: if you continue, how should you arrange it?
put right
Teacher: Just now, the children studied so hard that the graphic baby was a little unconvinced. It says it's no big deal, I have more difficulties here! Can you find it?
Show the third floor:
(1) What did you find?
(2) What do you want to tell the teacher?
(3) Teacher's summary
Second, children's operation exercises
Teacher: Just now, the children broke through three levels with their intelligence. Look, the kingdom of graphics has arrived. Do you want to play the kingdom of graphics again?
Please look at the children. On every table, there is a small gift prepared for you by the king of the graphic kingdom. You each take one, but there is one requirement: first find out the rule on the note, and then continue to add graphics according to this rule.
(1) One for each child.
(2) Teachers demonstrate the explanation methods.
(3) Children's collective operation
(4) communication between children.
Third, create
There are many roads to the kingdom of graphics. Do you want to design a regular road for children in other classes to test, so that they can get through?
Children's collective operation, design rules, exchange and display.
