Activity objectives:
1. Know this circle and use it to create shapes.
2. Develop children's imagination and operational ability.
3. Stimulate children's interest in learning graphics.
4. Guide children to actively interact with materials and experience the fun of mathematics activities.
5. Stimulate children's interest in learning.
Activity preparation:
1. Cut all kinds of colored paper into large and small circles and stick them on the magnet blackboard. Scissors, paste, round stickers, drawing paper, magnets, colors, etc.
2, children's math books
Activity flow:
(1) Tell the story of Bobo, who loves painting, to arouse interest.
Let the children guess what Bobo drew with the story. "Uncle Pig drew many large and small circles. My brother and sister watched them for a long time. I didn't know what Bobo's circle was, so I asked Bobo, "What is the circle you drew? "Bobo said," There are two hands in this circle, one is long and the other is short, and they go around from morning till night. My brother said, "Oh, I see, it's a clock." "My sister said," what is this? "Bobo said:" There is still a long line below, so we should grasp it well and don't run away. My sister said, "Oh, this is a balloon." . "Brother and sister finally know what Bobo painted. Bobo drew many circles, even the' circle' of the navel. Mother said, "Bobo is really a great painter. "
(2) Let children do puzzles by operating methods.
Children are bobo, too. Use round colored paper to put together a collage and see what shape you can put together. When finished, ask the children to appreciate the work and encourage them to tell what they made with the round collage.
(3) Lead children to open the first page of My Mathematics, inspire children to observe the contents of the picture, let children draw circles with their favorite colors, and then talk about what is round in the picture.
(4) Guide children to observe the surrounding environment and think and talk about what is round in life.
Teaching reflection
Through the activities of this lesson, children can distinguish circles from many objects and find the round objects in life through observation.
