"Understanding Triangle" Small Class Excellent Teaching Plan 1 Activity Goal
1. Know the characteristics of a triangle, and know that a triangle consists of three sides and three angles.
2. Can compare triangles with common objects in life and find out objects similar to triangles.
Activities to be prepared
1. A PPT, a big triangle, sticks of different lengths, ice cream sticks, etc.
Activity process
Finger Game: Happy Fish
2. Learn the characteristics of triangles
1, know the triangle
(1) Show Moline Yesterday, Mr. Zhang got a Moline. I brought him here today. Let's shout it out together 123 Please come out.
(A red Moline appears on PPT) Question: What color is it?
(2) The first change, this will change with Moline. Let's shout 123 and see what will happen. . (The children shouted 123 together, and three red lines appeared in PPT) Question: How many lines did the count become? (3) What is the second change (children shout 123 together, and a new triangle appears in PPT)? (triangle)
(4) touch the triangle teacher here also has a big triangle. I let the children touch it. Does it have three sides and three corners?
(5) Once again, a triangle has become many triangles. Although they are different in size, they are all triangles.
2. Consolidate the triangle features.
(1) Guide children to observe figures and find the characteristics of triangles.
Teacher Zhang went on a trip the other day. In a magical country, the Triangle Kingdom, everything here is triangular. The teacher photographed him and shared it with everyone today (continue to watch PPT and show all kinds of triangle items). A watch shop b food shop c hat shop.
(2) Let's see what else in the kingdom is triangular (many flags, roofs, ice cream, signs, etc.). )
(3) Guide children to look for triangular objects in the activity room. 3. The teacher summarizes the characteristics of the triangle, so that the knowledge acquired by the children is complete. (Showing the last PPT) You did a good job today. You found so many triangular objects. Although they look different (different shapes and sizes), they are all triangular. A figure with three sides and three angles is a triangle.
3. Review the characteristics of triangles. Provide sorbet sticks and small wooden sticks for children to spell triangles and consolidate their understanding of triangles.
Activity reflection
The thinking of small class children is the concrete thinking of images. They used magic to attract children's attention. They make triangles through a series of activities such as changing sides, touching, watching, watching and posing, so that each child can deepen his understanding of triangles in the process of spelling and posing in a broad space of activities and cognition, and teachers can also summarize them in time, so that children can gain the integrity of knowledge. Although there are fewer objects belonging to triangles in life, children can actively participate and observe and find many triangles in the environment.

Show the square handkerchief and guide the children to turn it into a triangle.
The child has a handkerchief in his hand. Operate it.
Third, guide the children to focus on the triangle and talk about what it looks like.
Fourth, the game "Happy Fish".
1, children read children's songs and do actions.
2, the teacher read: "swim to the triangle (square, round) pond", children swim to the corresponding area, do the action of small fish.
3. One child is a little teacher, giving instructions, and other children play with the teacher.
5. Enjoy the wall chart. Do you think it looks good?
Guide children to tell what shapes are unpainted. The teacher and a baby came to dress it up.
The children work in groups and color the circles, triangles and squares in the picture with their favorite colors. (soundtrack).
Activity expansion:
Children will show their works to teachers or other children, and talk about what colors they have drawn.
Attachment: Children's song Happy Fish
The fish swam and swam into a small pond.
Catch bugs and spit bubbles. It's really fun.
Excellent teaching plan of mathematics in small class III "Understanding Triangle" activity goal;
1. Guide children to initially perceive triangles, know their names and shape characteristics, and know the diversity of triangles in exploration and operation activities;
2. Triangles can be found without interference from other graphics;
3. Cultivate children's hands-on operation ability and develop the flexibility of thinking.
Activity preparation:
Teaching AIDS:
1, various triangles; Digital card;
2. Stars, diamonds and diamonds 1.
Learning tools:
1, 3 pieces of paper with different lengths (one set for each child);
2. Various graphics: circle, square, rectangle and triangle;
3. Graphic puzzles;
4, rubber pad with one hand.
Activity flow:
First, explore the operation:
1, please take three pieces of paper with different lengths and make a picture. Children's exploration activities, guided by teachers.
2, children show their own graphics, what kind of graphics teachers collectively talk about, with a few sheets of paper, there are several angles.
Second, understand the characteristics of the triangle
1, "Good boy! Now please invite today's graphic guests. " Show the triangle and guide the children to count the angles and sides of the triangle. (The teacher marks the triangle with numbers according to the angles and sides counted by the children. )
2. Show the stars, squares and diamonds to let the children know whether they are triangles.
3, show a variety of graphics, let the children put aside the triangle classification. (The second operation consolidates the understanding of triangle features)
4. Operation: Children are holding a graphic puzzle. Please find out the triangle and color in the picture.
5. Show your pictures to your parents.
Third, the activity is over.
Teaching reflection
My math class is to let children know triangles, and the difficulty is how to distinguish triangles from squares. In this teaching process, I put many sticks with different lengths on the children's desks and asked the children to count three sticks to form a triangle (you can find sticks with the same length or sticks with different lengths). By letting them operate, let the children further realize:
1, a triangle has three angles and three sides;
2. The lengths of the three sides of a triangle can be different, and the sizes of the three angles can also be different.
"Understanding Triangle" Excellent Teaching Plan for Small Class Mathematics 4 Kindergarten Small Class Mathematics Teaching Plan:
Know the moving target of triangle:
1, cultivate children's interest in graphics and math activities.
2. The initial development of children's ability to observe, analyze and summarize.
3. By perceiving and saying the basic features of a triangle, you can find a triangle-like object.
Activity preparation: one multimedia, one courseware and several graphics.
Activity analysis: observation and comparison are the process of children's exploration. It is the focus of this activity to guide children to perceive the basic characteristics of triangles through graphic comparison. In the activity, the courseware is intuitive and vivid, and through various forms of games, children are guided to further master and summarize the basic characteristics of triangles, thus breaking through the difficulties. At the end of the activity, organize children to further look for triangle-like objects from their living environment, as an extension of the activity, and naturally end.
Activity flow:
First, import. Draw a triangle by observing the tone of the graphic baby in the courseware.
