Triangle spelling teaching plan

As a people's teacher who specializes in teaching people to solve doubts, he often has to write an excellent teaching plan, which is helpful for the smooth and effective development of teaching activities. How to write a lesson plan? The following is the teaching plan of "Triangle Puzzle" I compiled for you. I hope it will help you.

Activity design of triangle puzzle lesson plan 1

1. Last semester, the requirements of the middle class for the development of children's mathematical graphics were: to further understand the characteristics of triangles, squares, rectangles and trapezoid, and to discover the relationship between the graphics. After children first studied graphics in small classes, the middle class gradually became interested in graphics.

2. The Guiding Outline of Kindergarten Education (Trial) points out: provide a relaxed environment for children's inquiry activities, so that every child has the opportunity to try, support and encourage them to ask questions boldly, express different opinions and respect others' opinions. Provide rich operational materials, and provide each child with a variety of senses and ways to explore conditions. 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 to spell isosceles right triangles with the same size. How to make it interesting? Therefore, in the context of children's favorite animated stories, a game is designed, which is from easy to difficult, step by step, and from concentration to divergence. Children can stimulate their interest by crossing rounds of obstacles. By getting a small red flag as a reward, let them experience the sense of accomplishment brought by success and improve their observation ability, thinking ability and hands-on operation ability.

(1) Observe the first level through the diagram to understand the requirements of the puzzle.

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

(2) according to the graphic puzzle.

③ AC summary puzzle method: First, put two triangles of equal length together and lean together to form a square, and then add a small ladder on both sides to form a trapezoid.

2. What problems did the second level of Big Big Wolf give us? (Show the second customs clearance map)

(1) Understand the requirements of the third level. What number is it? How many triangles are there? The wolf wants the children to put together a new figure with four triangles. Every child must complete three different spellings to succeed! Let's start!

2 Complete the puzzle independently.

③ Communication: What number 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 have not completed the three spells will try again!

3. Is the third level more difficult? Cheer for yourself! (Show transit map)

(1) What is this number? Is it made up of several small triangles? How about counting? The wolf wants children to make a big triangle with eight small triangles!

Try to break through the puzzle.

3 communication and presentation: what picture are you spelling?

Third, the activity is over and sorted out.

Teacher: What clever hands you have, children! Make various figures with triangles, successfully defeat the wolf and rescue the beautiful sheep. The wolf said, "I will definitely come back!" " "Give yourself a little applause!

Activity reflection:

According to the thinking characteristics and lively personality of small class children, I weave triangle graphic characteristics into short stories, and then combine graphic puzzles to let children learn while playing. Make children develop good habits of hands, mouth and brain, and cultivate their innovative consciousness.

"Triangle Puzzle" Teaching Plan 2 Activity Objectives:

2. Operational activities.

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

(The child tries again) Teacher: What number are you spelling? Who will spell it for everyone? (Let three children spell out three different shapes) Teacher: Let the children spell out the shapes that you didn't spell out.

3. summary.

Teacher: The children's little hands are really capable. They spell out rectangles, squares, big triangles and trapezoid with triangles. Next time, the teacher will let the children play jigsaw puzzles with various shapes.
