Part One: Learning Objectives

Through the practical activity of making three-dimensional models based on three views, experience the process of transforming flat graphics into three-dimensional graphics, and understand the role of using three views to represent three-dimensional graphics;

Further experience the connection between three-dimensional graphics and two-dimensional graphics.

Topic learning to make three-dimensional model PPT, the second part of the content: independent learning

Independent learning tasks:

1. Take advantage of the practical activity of making three-dimensional models based on three views and experience the process of transforming flat graphics into three-dimensional graphics.

2. Feel the connection between three-dimensional graphics and two-dimensional graphics

Independent learning feedback

1. As shown in the figure is a three-dimensional view of a packaging box, the volume of this packaging box is __________.

2. The three views of a triangular prism are as shown in the figure. It is known that the areas of the front view, left view and top view are 12, 4 and 3 respectively, then the length of MN in the left view is ____.

The main stadium of the 2008 Beijing Olympic Games - "Bird's Nest"

National Aquatics Center - "Water Cube"

China Pavilion at Shanghai World Expo 2010

In order to study chemical substances, scientists create three-dimensional models of substance molecules

All kinds of architecture are inseparable from its prototype - three-dimensional model

Activity

1. Using cardboard as the main material, make the three-dimensional models represented by the two sets of views below.

Topic learning to make three-dimensional model PPT, the fourth part: in-class testing

According to the two sets of views given below, make the corresponding physical model using potatoes (or radishes).

Each set of plane figures below is composed of four equilateral triangles.

(1) Point out which of them can be folded into polyhedrons, trace the above figures on paper, cut them out, fold them into a pile, and verify your answer;

(2) Draw a three-dimensional view of the polyhedron that can be folded from the above figure, and point out how the three views reflect "the length is aligned, the height is equal, and the width is equal";

(3) If the side length of the small triangle in the picture above is 1, what are the volume and surface area of ​​the corresponding polyhedron?

Topic learning to make three-dimensional model PPT, Part 5: Class summary

1. Mathematics is a science whose main research objects are quantitative relationships and spatial forms. Quantitative relationships and spatial forms are abstracted from the real world.

It is obvious that knowledge about projections and views arises from practical needs (architecture, manufacturing, etc.) and they are very closely related to the actual model.

2. Perceptual knowledge needs to be upgraded to rational knowledge, and practice under the guidance of theory will be more clear and effective.

3. In terms of skills, understanding the connection between plane graphics and three-dimensional figures will help to realize the mutual transformation between them as needed, that is, learning to draw three views and drawing three-dimensional figures from three views. In terms of ability, understanding the plane The connection between graphics and three-dimensional graphics is very important for cultivating spatial imagination ability.
