1. Guide children to distinguish circles, triangles, rectangles and squares, and classify them according to their marks.
2, through situational games and other activities, let children initially perceive the transformation relationship between graphics, and can find a solution to the problem.
3. Cultivate children's thinking flexibility, develop children's practical ability, and stimulate children's desire to learn mathematics.
Activity preparation:
1, learned the characteristics of various graphics.
2. Self-made \ "path \" with carved figures \ "pits \" of different sizes, and the carved figures are made into \ "stones \" to pave the way. There are as many baskets as children.
3. Graphical symbols of circles, triangles, rectangles and squares, and music.
Activity flow:
First of all, introduce "picking stones" into the scene to stimulate children's interest in activities.
1, \ "It's a beautiful day, son. Let's go to the suburbs to pick up stones! \ "(enters the activity room with music) 2. The teacher asked for the operation: "Look! There are so many colorful stones that everyone can choose what they like. \"3. Guide children to observe the operation and encourage them to communicate while operating.
4. Ask children to boldly introduce their favorite stones (colors and shapes).
5. Game: Hold the "stone" according to the mark.
Second, paving stones:
1, "Everyone has picked up so many beautiful stones. Do you want to use them to pave a gravel road? \"2. Children can operate freely: embed the found "stone" into the corresponding "pit".
3. There is a problem: \ "There are no pebbles, but there are pits that have not been paved. What should I do? "4. The child will operate again.
5. Found the problem: "The teacher found a special stone here, which was put together with two colors of stones." Ask individual children to introduce his method.
6. Guide children to find ways to cooperate and use "stones" to lay "pits" on the ground.
7. Teacher's summary: You can spell out several new figures with different shapes.
Third, step on the stone:
1, \ "The road is paved, let's play the game of stepping on stones! The teacher introduced the game: "As soon as the music rang, the children began to move while reading children's songs. As soon as the music stopped, they immediately stepped on the "stone" and talked about what shape and color they stepped on.
2. The game is repeated 2~3 times.
3. Let the children find out whether there are such pictures and texts in the kindergarten and end the activity.
Activity expansion:
1, children's operation data are put into the activity room to calculate the angle, so that children can continue to operate in free activities.
2. Let the children go home to find and think about what circles, triangles, rectangles and squares are in daily life, tell the teacher after returning to the park, and list the charts.
