First, the game: find a graphic doll in the "wonderful box"

Teacher: Today, the teacher brought a wonderful box. Do you want to know what secrets are hidden in it?
2. The teacher reads children's songs: There are many things in the wonderful pocket. Let me touch it first and see what it is.
Take out the rectangle
Q: What is this? Why do you say she is rectangular?
In our daily life, what things are rectangular?
(Guide the children to discuss)
3. Read children's songs again: There are many beautiful things in your pocket. Please touch so-and-so children.
When children touch a graphic, they are required to tell the name and characteristics of the graphic. What other such items are there in life?
The game is repeated.
4. Teacher's summary: There are circles, triangles, squares, rectangles, trapezoids and ellipses in the wonderful box.
(1) A triangle has three angles and three sides;
(2) A square has four sides and four corners, the four corners are equal in size and the four sides are equal in length;
(3) A rectangle also has four corners and four sides, the four corners are equal in size and the two opposite sides are equal in length;
(4) A trapezoid also has four sides, two opposite sides are parallel sides, and two oblique sides are beside it;
(5) Both a circle and an ellipse are round and have no corners. The edges are smooth to the touch, but the ellipse is flat.
Second, collage
1, Teacher: Children are really capable, so the graphic doll wants to play a game with us.
There are many graphic babies on the plate. Please choose your favorite graphics later and add a few strokes to them to turn them into other interesting items.
You can also use several graphics to make various other items. Let me see which child is the cleverest and changes things differently from others.
2. Inspire children to imagine boldly and add another object to the geometric figure.
3, the game-graphic card game.

1, please tell some children: What graphic baby did you use to change it? Into what?
2. How many things have you changed with the round one? Who has changed the most (the most obvious performance)
3. Triangle, square, rectangle, trapezoid and ellipse are arranged in sequence.
