Description

"Understanding of Cones" Cylinder and Cone PPT Courseware

teaching objectives

1. Through observation, discussion and hands-on operation, students can understand cones, master the characteristics of cones, and learn to measure the height of cones.

2. Let students learn to recognize cones through observation and hands-on operation.

3. Cultivate students’ self-exploration and innovative spirit.

Default self-exploration

1. Understand the cone. How many parts does it consist of? And know the names and characteristics of its parts.

2. What is the height of a cone? How to measure its height?

3. According to the drawing on Appendix 2, two people at the same table work together to make a cone out of cardboard. Think about how to measure its base diameter and height? And try to measure it.

Mark “√” if correct and “×” if incorrect

①The side surface of a cone is a curved surface. ( )

②The sides of a cylinder are rectangular when unfolded, and the sides of a cone are also rectangular when unfolded. ( )

③The line connecting the vertex of the cone to any point on the bottom is called the height of the cone. ( )

④The base of the cone is circular. ( )

The distance between the apex of a cone and the center of the base is the height of the cone.

The cone has only one height.

The base of a cone is round.

The side of a cone is a curved surface, and the side expansion is a fan shape.
