Description
"Surface Area of Cuboids and Cubes" PPT courseware for understanding cuboids and cubes
teaching objectives
1. Understand the meaning of the surface area of cuboids and cubes.
2. Understand and master the calculation method of surface area of cuboid and cube.
3. Cultivate and develop students’ spatial concepts.
Research recommendations
Ask the students to use the cuboid in their hands to find the surface area of the cuboid by measuring, cutting, spelling, and arranging it. At the same time, record the discussion results (no limit to the form) and see which group There are many ways to think of it.
In groups of four, start operating, discussing, and calculating the surface area of the cuboid. (This activity lasts about 10 minutes)
The size of a cuboid is as shown in the figure.
(1) The total area of its upper and lower surfaces is——dm2.
(2) The total area of its front and back faces is——dm2.
(3) The total area of its left and right faces is——dm2.
(4) Its surface area is——dm2.
Use 8 cubes with sides of 1 cm to form cuboids or cubes of different shapes.
(1) Guess whether their surface areas will be equal?
(2) Put it aside and do the math.
(3) Is the size of the surface area related to the shape?
Summarize
