"Translation" graphic motion PPT download

Part One: Learning Objectives

1. Through observation and operation, further understand the translation of graphics, master the characteristics of translational motion, and develop spatial concepts.

2. Experience the process of translating simple figures in the square horizontally or vertically, accumulate experience in graphic movement, and penetrate and transform ideas.

3. Flexibly use translation knowledge to transform irregular graphics into regular graphics to solve problems, and further understand the application of the movement of graphics in solving problems.

Panning PPT, part 2: introduction of new lessons

What are the characteristics of the translation phenomenon?

In the second grade, we already knew the translation phenomenon in life. What other translation phenomena have you seen?

The size and shape of the graphic remain unchanged, only the position of the graphic changes.

Panning PPT, the third part: interpretation of examples

What has not changed about the graphics before and after the translation? What has changed?

The shape and size remain unchanged

location changed

What is the area of ​​the figure below?

This figure has two sides that are curves. How do you calculate the area?

Give it a try using the knowledge you have learned about graphic motion.

Panning PPT, Part 4: Summary

Method for determining the direction and distance of translation of graphics in a square grid

(1) Determine the direction of translation according to the direction of the arrow;

(2) Find a set of corresponding points of the two figures before and after the translation;

(3) Connect the symmetry points in sequence to complete the figure.

How to draw simple graphics in a grid after translation

(1) Select points on the original graphic that can basically determine the shape and size of the graphic;

(2) Translate the selected point to the specified direction by the specified number of grids as required;

(3) Connect the translated points to form a line.

Panning PPT, the fifth part: quiz in class

1. Color the result obtained after moving 4 spaces to the right.

2. Draw the graphics obtained by moving 3 spaces upward and 8 spaces to the left.

3. First complete the axially symmetrical figure below according to the axis of symmetry, and then draw the axially symmetrical figure translated 10 blocks to the right.

What knowledge of graphic motion is used here?

Both axial symmetry and translation knowledge are used.

Panning PPT, Part 6: Homework

1. Choose from the after-school exercises.
