Elementary school mathematics abstract teaching planThe following are some elementary school mathematics abstract lesson plans:
** 1. Teaching plan for understanding the rectangular, square and circle **
1. ** Teaching goal **
- Through practical activities, students will have perceptual knowledge of cuboids, cubes, columns, spheres, as well as cuboids, squares, circles, and triangles, and be able to recognize their names. He could feel the connection between the form and the body.
- He applied his knowledge to his daily life and judged the shape of objects in his daily life.
- Cultivate the students 'observation skills, spatial concepts, and hands-on operation skills.
2. ** Teaching Difficulties **
- ** Important point **: Students will be able to intuitively recognize the rectangular, square, and circle in the activity exploration, and be able to abstract the planar figure from the surface of different objects in life.
- [Difficulty: Let the students abstract a planar figure from the surface of an object and feel the connection between the shape and the body.]
3. ** Teaching process **
- For example, let the students touch a bag with cuboids, cubes, columns, balls, and other objects, and then tell them the shape and characteristics of the objects they touched.
- The students were guided to observe the footprints of different shapes, find footprints, draw footprints, divide footprints, recognize footprints, and so on.
- Ask the students to give examples of objects in their daily lives that are rectangular, square, or round in order to enhance their understanding of the shapes.
** 2. Polygon (such as a quadrilateral, triangle, echelon, etc.) teaching plan **
1. ** Teaching goal **
- Let the students grasp the characteristics of the shape of a hexagon (such as a quadrilateral, triangle, echelon, etc.).
- To make students understand the core methods of calculating the area of a hexagon (such as conversion-known-unknown, cut and divide, combination, cut or supplement conversion, etc.).
- Through practical homework, students could improve their core mathematics quality.
2. ** Teaching Difficulties **
- ** Main point **: Teach the shape characteristics of a hexagon and related calculation methods.
- [Difficulty: Guide students to use transformation thinking to calculate the area of a hexagon and understand the relationship between the graphs.]
3. ** Teaching process **
- Divide the teaching modules, such as the knowledge points such as paralleled quadrilateral, triangle, echelon, and hexagon.
- He explained the core calculation methods, such as using methods such as cutting, combining, and so on to transform the unknown figure into a known figure for calculation when calculating the area of a triangle.
- Arrange practical assignments, such as making a graphic mold frame, building a graphic combination tool, calculating and drawing a polygraph, etc., so that students can understand the knowledge of the polygraph in practice.
** 3. Teaching plan for mathematical graphs (related to mathematical graphs)**
1. ** Teaching goal **
- Combining the problem situation, he experienced the process of abstracting real-life problems into mathematical problems of graphs and using a variety of drawing strategies to solve the problem, developing geometric intuition.
- In the process of counting the figures, gradually form a good habit of orderly thinking and develop reasoning ability.
- In the process of discovering the rules, they could think independently and explore independently, enhance their self-confidence in learning, and increase their interest in exploring mathematical problems.
2. ** Teaching Difficulties **
- ** Main point **: Experience the process of abstracting real-life problems into mathematical problems and using a variety of drawing strategies to solve the problem.
- [Difficulties: Gradually form a good habit of thinking in an orderly manner, summarize and discover patterns, and develop reasoning skills.]
3. ** Teaching process **
- Create a situation, such as a "mole drilling hole" or a modified "riding a bullet train" situation. Take the example of "mole burrowing". First, let the students think about how many different paths the little mole can take and guide the students to solve them in different ways. For example, some students might describe it in words, while others might use symbols to express it.
- In the process of counting figures (such as the number of line segments), guide the students from simple to complex. For example, start from 4 points, count the line segments without repeating or missing, and then gradually increase the number of points to 5, 6, etc., so that the students can feel the value of orderly thinking and discover the rules in this process.
- The migration law could solve other similar problems. For example, in the case of "vegetable field travel"(or train ticket problem), the method learned from "mole drilling hole" could be used to solve the problem of the number of line segments (the type of ticket) corresponding to different points.
