Teaching objective: 1. Learn to recognize symmetrical figures through the process of observation, operation and comparison.
2. Through the participation of various senses and forms, we can perceive the characteristics of symmetrical figures and find out the axis of symmetry.
3. Experience cutting, spelling and painting, develop the concept of space, cultivate the ability of observation and hands-on operation, and experience the joy of learning.
Emphasis and difficulty in teaching: the characteristics of symmetrical graphics.
Teaching preparation: exercise paper, graphic paper, scissors, courseware, etc.
Teaching process:
First, create a situation
There are many butterflies on the beautiful grass.
2. What do you think of this painting? Where are the butterflies?
Let's study it from the angle of mathematics today! (Courseware demonstration: Butterfly wings folded and unfolded)
Second, understand symmetrical graphics
1, the teacher brought a lot of graphics to see what graphics there are.
2. Fight. Can you choose two of the above pictures to make the following pictures?
First, the student operation, teacher guidance.
Let the students show their works.
C. Besides these figures, can you spell other figures of the same type?
D, student show.
3. Are the children spelling correctly? Let's take a look at the characteristics of these graphics first.
Health: the same; Folding in half will overlap ...
Look at the numbers spelled by our classmates. Are they different? (verification)
Step 5 get a name
Let's give a name to a character like this. (symmetrical figure)
What are the characteristics of symmetrical graphics?
6, contact life to find symmetrical graphics.
Third, hands-on operation, making symmetrical graphics.
Teacher: There are so many symmetrical figures in life. Now let's make a symmetrical figure. We want to be a small pine tree. Is there any good way?
Student: Draw a picture (how? ) draw half a tree/cut it directly.
Teacher: Then let's try!
Show students' works. How did you cut it?
Only by cutting in this way can we be symmetrical. We call this crease the symmetry axis, and the left and right sides of the symmetry axis have the same shape. (Courseware shows symmetry axis)
Can you draw this symmetry axis?
Fourth, judge the symmetrical figure and draw the symmetrical axis.
1. Observe carefully and judge whether these patterns are symmetrical. Talk about the method of verification.
2. Draw the symmetry axis of the symmetrical figure.
3. Draw a symmetry axis of a square and a circle (maneuver)

2. After the above picture is expanded, it is the following picture, which is connected by lines.
3. Facebook appreciation. Show half, let the students imagine the complete face, and then present it.
Expand after class and enrich knowledge.
Symmetric graphics are widely used in our lives, ancient and modern, at home and abroad. We have a hundred math gardens.
