"Translation" Axis Symmetry and Translation PPT
Description
"Translation" Axis Symmetry and Translation PPT
Part One: Classroom Introduction
1. Guide students to learn in active situations so that they can have a deeper understanding of translation.
2. Let students experience the geometric characteristics of translation after experiencing the "guess-verify" learning process.
3. Enable students to learn mathematical exploration methods while learning mathematical knowledge.
Panning PPT, part 2: exploration of new knowledge
Look at the motion of the following objects...
Translation - movement along a straight line
Translation characteristics:
The shape and size of the graphics remain unchanged before and after translation, only the position of the graphics changes. Each part of the graph moves the same distance before and after translation.
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?
The distance of translation is the distance between corresponding points, not the distance between two figures.
Panning PPT, Part 3: Classroom Exercises
1. Draw a picture and tell your partner how you drew it.
2.⑴The small house first moved ___ squares to ___, and then moved ___ squares to ___.
⑵The trapezoid first moved ___ squares toward ___, and then moved ___ squares toward ___.
⑶Tell me, how else can these two pictures be moved to their current position?
The small house can also be moved down 3 spaces first, and then 4 spaces to the right; the trapezoid can also be moved up 4 spaces first, and then 9 spaces right. (The translation method is not unique)
3. Put the figure below into an axially symmetrical figure. Let’s talk about it. How to translate when drawing?
The flower on the left first translates 2 spaces to the right, and then translates 2 spaces downward;
The flower on the right first moves 2 squares upwards, then 2 squares to the left.
Panning PPT, Part 4: Class Summary
How to draw a simple figure on graph paper that is translated horizontally and vertically:
When drawing a picture, first find one or several key points, translate them, and then draw the complete figure.
The translation distance is the distance between corresponding points.
The size and shape of the graphic cannot be changed during translation.
Panning PPT, Part 5: Classwork
1. In the square, draw a shape in which the fish first moves 8 blocks to the right and then moves 3 blocks downward.
2. Draw the translated shape of the triangle as required.
The original parallelogram became a rectangle and a square.
3. Move the left graphics 5 spaces to the right, and the right graphics first 6 spaces upward, then 8 spaces to the left, and draw.
