"Translation" Axial Symmetry and Translation PPT Download

Part One: Learning Objectives

1. Through observation, operation and other activities, further understand the translation of graphics on graph paper and experience the characteristics of translation motion.

2. Able to translate simple graphics horizontally or vertically on graph paper.

3. In the process of drawing, accumulate the thinking concept of graphic movement and develop the concept of space.

focus

Able to translate simple graphics horizontally or vertically on graph paper.

difficulty

Accumulate the thinking concept of graphic movement and develop the concept of space.

Panning PPT, Part 2: Interpretation of Examples

The movements of the following graphics are all translations.

Please draw the shape obtained by moving the flag 4 spaces to the left, and communicate with your companions. Can you answer Xiaoxiao’s question?

Then start from the translated point and follow the original picture...

Find a point on the flag and move it 4 spaces to the left.

Why is the result after I moved different from the naughty result?

Let me draw a picture.

Xiaoxiao made the mistake of interpreting the translation distance as the distance between the graphics before and after the translation. That is, there is a difference of 4 intervals between the leftmost end of the small flag before the translation and the rightmost end after the translation. In fact, the small flag moved 7 spaces to the left.

Typical examples

Draw the translated shape of the triangle as required. Tell me, what kind of shape did the original parallelogram become?

Panning PPT, the third part: summary

How to translate simple graphics on graph paper

(1) Find the key points of the given graph;

(2) Translate the corresponding number of grids as required and draw each corresponding point (or corresponding line segment);

(3) Connect these corresponding points (or corresponding line segments) according to the shape of the given figure.

Panning PPT, the fourth part: quiz in class

1. Which of the following graphics can overlap with the shadow graphics through translation? Use a pen to paint them out.

2. Draw a picture and tell your partner how you drew it.

Panning PPT, Part 5: Homework

1. Select from the after-class exercises;

2. Complete the exercises in this lesson in the exercise book.
