Teaching plan of triangle puzzle

As a people's teacher who specializes in teaching others and solving doubts, he often has to write an excellent teaching plan, which is helpful to carry out teaching activities smoothly and effectively. How should we write lesson plans? The following is the teaching plan of "Triangle Puzzle" I compiled for you, hoping to help you. The teaching plan of "Triangle Puzzle" 1

Activity Design 1. The requirements of the middle class for the development of children's mathematical graphics last semester are: to further understand the characteristics of triangle, square, rectangle and trapezoid, and to discover the relationship between the graphics. After children's initial study of graphics in small classes, middle classes gradually became interested in graphics.

2. It is pointed out in the Guiding Outline of Kindergarten Education (Trial) that a relaxed environment is provided for children's inquiry activities, so that every child has the opportunity to try, support and encourage them to boldly ask questions, express different opinions and respect other people's opinions. Provide a wealth of operational materials, and provide conditions for each child to explore in a variety of senses and ways. By guiding children to actively participate in group discussion and exploration, we can cultivate children's awareness and ability of cooperative learning and learn to express, communicate and share the process and results of exploration in various ways.

3. In regional activities and daily games, children like to use different graphic combinations to piece together new graphics and shapes. This lesson focuses on trying and spelling isosceles right triangle with the same size. How to make it interesting? Therefore, taking the children's favorite animated stories as the situation, we designed a game to break through the barrier from easy to difficult, step by step, and from concentration to divergence. Children can stimulate their interest by going through rounds of barriers. By getting a small red flag as a reward, they can experience the sense of accomplishment brought by success and improve their observation ability, thinking ability and hands-on operation ability.

moving target

1. Try to spell out rectangles, squares, large triangles and trapeziums with isosceles right triangles.

2. Understand the relationship between parts and the whole by trying and spelling.

3. Experience the sense of accomplishment and the happiness brought by the jigsaw puzzle.

4. Promote the whole body movement through dance activities.

5. Experience the pleasure brought by singing activities.

Activity preparation

Material preparation:

1. Teaching AIDS: There are several magnetic triangles, one entry map, and 12 triangles of the same size.

2. Learning tools: several triangles of the same size, several flags (with toothpicks on them), each with a bottom plate.

Experience preparation:

1. Understand the meaning of the game, and play the game.

2. Know and understand the characteristics of triangle, square, rectangle, trapezoid and diamond.

3. Try to spell another figure with two triangles or spell different shapes with three or more triangles in regional and other game activities.

activity process

first, the scene is introduced to arouse interest.

teacher: do you know? Last night, the beautiful sheep was taken away by the big wolf again, and she felt particularly sad.

jubilant: children, would you like to help me get through the customs and rescue Meiyangyang?

2. Go deeper and deeper, and the puzzle will break through

1. Teacher: What kind of obstacles did Big Wolf set for us? Let's have a look together. Please look at the first level! (Show the first clearance figure)

① Observe the first clearance figure to understand the requirements of the puzzle.

what is this figure? How many triangles are there? What figure do these three triangles make up? It turns out that Big Wolf wants children to make a trapezoid with three triangles. Can you finish the task?

② Break through the puzzle according to the diagram.

③ the method of communication summary jigsaw puzzle: first, put two triangles with the same length together and close together to form a square, and then add a small ladder to the sides to form a trapezoid.

2. What problem did Big Wolf give us in the second pass? (Show the figure of the second customs clearance)

① Understand the requirements of the third customs clearance. What figure is it? How many triangles are there? Big Wolf wants the children to put together a new figure with four triangles. Every child has to complete three different spellings to be successful! Let's start!

② Complete the puzzle independently.

③ communication: what figure did you spell? How do you spell it? Summary: Four triangles can be spelled into rectangle, square, big triangle, trapezoid and parallelogram.

④ children who haven't finished the three spellings try again!

3. Is the third level more difficult? Come on for yourself! (showing the figure of crossing the border)

① What figure is this? Is it made up of several small triangles? How about counting it? Big Wolf wants children to make a big triangle with eight small triangles!

② try to break through the puzzle.

③ communication presentation: what figure did you spell?

third, the activity is over and sorted out.

teacher: what clever hands you have, children! Made all kinds of figures with triangles, successfully defeated Big Wolf and saved Meiyangyang. Big Wolf said, "I will definitely come back!" " Give yourself a round of applause!

activity reflection:

according to the thinking characteristics and lively personality of small class children, I weave the graphic characteristics of triangles into short stories, and then combine them with graphic puzzles to let children do it while playing with middle school and learning. Make children develop good habits of hands, mouth and brain, and cultivate children's innovative consciousness. "Triangle Puzzle" teaching plan 2

Activity objectives:

1. Guide children to spell out rectangles, squares, large triangles and trapezoids with triangles.

2, in the exploration activities, develop children's hands-on ability and thinking ability, and experience the sense of accomplishment in the activities.

3. Let children experience the fun of math activities.

4. Develop children's logical thinking ability.

Activity preparation:

1. Teaching AIDS: 12 magnetic triangles.

2. Learning tools: several triangles of the same size (4 for each child).

Activity process:

1. Group activities.

Teacher: Rabbit likes triangles best. It thinks triangles have great skills and can spell out various figures. The teacher has prepared many triangles for the children. I want to invite the children to pose and spell together to see if what Rabbit said is true.

teacher: who will tell me how you spell it? From: big; Teacher: The teacher has a request that each child take four triangles and use them to make a big rectangle.

2. Operation activities.

teacher: who will spell it? Teacher: Just now, the children spelled a big rectangle with four triangles. What other figures can we spell with four triangles? (Big triangle, square, trapezoid) Teacher: Go and have a try. Let's see who can spell faster and better.

(The child tries again) Teacher: What figure did you spell? Who will spell it for everyone? (Ask three children to spell three different shapes respectively) Teacher: Ask the children to spell the shapes you haven't spelled.

3. Summary.

Teacher: The children's small hands are really capable. They spell out rectangles, squares, big triangles and trapeziums with triangles. Next time, the teacher will ask the children to play jigsaw puzzles with various figures.
