What should be paid attention to in the teaching of solid geometry

1. The teaching goal of defining spatial geometric structure is to understand the structural characteristics of columns, cones, platforms, spheres and their simple combinations, and use these characteristics to describe the structure of simple objects in real life, thus developing the ability of geometric intuition. Guide students to understand space geometry from the structural characteristics of space geometry, drawing three views and straight views, measurement and calculation.

2. Strengthen the teaching of geometric intuition and logical reasoning, conduct appropriate speculative argumentation, and cultivate students' spatial imagination ability from various angles such as geometric intuition and logical reasoning.

3. Pay attention to understanding geometry from different angles.

Geometric classification-application of comparison method;

The method of describing the structural characteristics of geometry-the elements that make up geometry and their positional relations, and the structure of simple geometry is described by using the known structural characteristics;

4. Make full use of cuboid model and attach importance to the application of modern educational technology;

5. Pay attention to the occurrence and development of the concept theorem;

6. Pay attention to the teaching and practice of mathematical problem expression: borrow mathematical symbols instead of Chinese characters.
