Learn to observe objects and geometric figures from different angles. The main contents include identifying the shapes of geometric assemblies observed from different positions and different geometric assemblies observed from the same position. These contents are the basis of further study and play an important role in cultivating students' spatial imagination and reasoning ability.
Teaching objectives:
1. Cultivate students' ability to observe and analyze things from different angles, and cultivate students' ability to construct simple space imagination.
2. Let the students know that when they stand in different positions to observe objects, they see different shapes, and they can see up to three faces in one position.
3, can identify the front, side and top of the object.
4. Learn to recognize the shapes of objects observed from different positions.
