Description

"Motion of Figures" PPT (Rotation in Lesson 1)

Part One: Learning Objectives

1. Further understand the rotation of graphics, clarify its meaning, understand its characteristics and properties, and be able to use mathematical language to simply describe the process of rotation.

2. Understand rotation changes through observation, imagination, operation, description and other activities.

[Key Points] Communicate and connect through a variety of learning activities, understand the meaning of rotation, and understand the characteristics and properties.

[Difficulty] Use mathematical language to describe the rotation process of graphics.

Graphical motion PPT, part 2: introduction of new knowledge

What is this phenomenon?

rotation phenomenon.

Do you know the names of these two spins?

Example 1 Who can completely describe the rotation process just now in one sentence?

From "12" to "1", the pointer rotates 30° clockwise around point O.

Watch the animation carefully and fill in the blanks.

From "1" to " ", the pointer rotates 60° clockwise around point O.

Watch the animation carefully again, and then fill in the blanks.

From "3" to "6", the pointer rotates ____° clockwise around point O.

Graphical sports PPT, part 3: classroom exercises

1. Look at the picture and fill in the blanks. As shown in the figure below, it is known that the pointer rotates 90° clockwise around point O from this position to "green".

(1) The pointer rotates 180° clockwise around point O from this position to ().

(2) The pointer rotates 90° counterclockwise around point O from this position to ().

Graphical sports PPT, part 4 content: Class summary

What did you gain?

01 There are two directions of rotation: counterclockwise rotation and clockwise rotation

02 Pendulums and swings that do not complete one full revolution are also rotating.

03 Rotation has three elements, rotation center, rotation direction and rotation angle.

04Rotation refers to the phenomenon of an object moving around a certain point or axis.

05After the graphic is rotated, its shape and size do not change, but its position changes.

Graphical motion PPT, part 5: homework

Fill it out.

① Rotate 90° counterclockwise around point O in Figure 1 to reach the position ( ) in Figure 1.

② Rotate clockwise ( ) around point O in Figure 2 to reach the position in Figure 4.

③ Rotate 90° in the ( ) direction around point O in Figure 3 to reach the position in Figure 4.
