Which lesson plan should be filled in for small class mathematics?

Textbook: The detailed rules of the Outline stipulate that "teachers should take the surrounding things and phenomena that children are interested in as the objects of scientific inquiry." Children in small classes are very interested in graphics and colors. This activity aims to attract children's attention by using the form of body-spelling graphics, so that children can have a further understanding of the graphics they have learned. Furthermore, by appreciating pictures and spelling graphics, children's innovative thinking ability and hands-on operation ability can be promoted, which is more conducive to stimulating children's interest in learning and promoting children's bold thinking and positive creative desire. Second, the activity goal: 1, creatively combine graphics on the basis of understanding circles and triangles. 2. Guide children to try to evolve circles and triangles with their own bodies, and consolidate children's perception of the characteristics of circles and triangles. 3. Stimulate children's desire to explore and cultivate their hands-on ability. Third, activity preparation: 1, PPT courseware; 2. Children's operation materials: a number of small circular and triangular figures and a number of white papers; Some spelling charts and colored pens. Fourth, the focus of the activity is to guide children to evolve into circles and triangles with their own bodies. Solution: Children's perception of circular and triangular features. Activity difficulty: Try to combine figures with circles and triangles. Solution: through a pleasant storyline, 5. Activity flow: 1, introducing the story of "graphic kingdom" to guide children to perceive the characteristics of circles and triangles; (1) Show circles and triangles to guide children to talk about the characteristics of circles and triangles. (2) Teacher's summary: A circle has one side but no angle, and a triangle has three sides and three angles. 2. Guide children to evolve graphics with their bodies: (1) The triangles and circles in the "graphics kingdom" want to play hide-and-seek with children. Ask the children to find the graphic treasure hidden in the teacher and say whether it is a triangle or a circle. (2) Guide children to use their own body evolution graphics to find triangles and circles hidden in children's bodies. 3. Appreciate the combination puzzle of circles and triangles: (1) Show different pictures of circles and triangles in turn to guide children to talk about which ones are circles and which ones are triangles. How many circles and triangles are there? (2) Teacher's summary: Everything in the graphic kingdom is composed of triangles and circles. Triangles and circles can make up fish, chickens, flowers, houses and many other things. 4, children's group operation, teacher guidance: (1) In the first group, the teacher instructed children to spell out graphics with circles and triangles of different sizes and colors. (2) In the second group, find out the circles and triangles in the painting and paint them with different colors according to the prompts. 5.End: Let the children introduce you to what graphics they have spelled or drawn, and let them all join the graphics kingdom.
