Trapezoidal middle class lecture script, trapezoidal where is the middle class lesson plan

The lesson plan for the middle class of "Trapezoidal in **" is as follows:

Activity Objectives:1Perceive the basic characteristics of trapezoids and consolidate the knowledge of geometric shapes.

2.You can find trapezoids in various shapes without the interference of other shapes, and learn to use a variety of methods to turn various shapes into trapezoids.

3.Develop children's observation, imagination and hands-on skills.

4.To further enhance children's interest in trapezoidal activities and hands-on skills.

5.Be open to exploring, communicating and sharing.

Key difficulty: Teaching focus: Preliminary understanding of the characteristics of trapezoids. Teaching difficulty: Use a variety of methods to turn various shapes into trapezoids.

Preparation for the activity: 1. Preparation for the creation of the environment: Put some pictures containing trapezoids in the activity room.

2. Teacher's demonstration tools: self-made animal models (round mouth of the little monkey, triangular mouth of the little rabbit, etc.) and several geometric biscuits (triangles, rectangles, squares, circles, etc.) and many more courseware. 3：

Infant learning aids: Contains several pictures with trapezoidal shapes (not colored).

Activity process: 1. Game: Feed cookies to small animals.

2. Observe and understand the trapezoidal features.

1) Show the trapezoidal shape and ask: How many sides are there? How many corners? What does this graphic look like?

2) Summary: This slide-like figure is called a trapezoid.

3) A wide variety of trapezoids. (Show more than ** courseware).

4) Is the figure of the two sides the same length and only one side is a slide?

3. Operation. Find trapezoidal biscuits among the various graphic biscuits and feed them to the small animals. Request? I want to take one piece of the tall and feed the animals with two different trapezoidal biscuits.

4. Find a trapezoid.

1) Look in the classroom, in the yard, and talk about it.

2) Show the courseware: look for the trapezoidal baby.

5. Group activities.

1) Dress the trapezoidal (color).

2) Spell a spell: use rectangles, squares, triangles to spell trapezoids.

6. Summary, end.

Teaching reflection: for the trapezoid, most children have a perceptual understanding of him, this lesson I combined with the children's perceptual understanding design: feed cookies to small animals, find one, paint one, take a look, spell a spell and other links, strengthen this perceptual understanding, and at the same time, through comparison, the teacher's point, the understanding rises to a rational understanding.

A variety of forms of activities, fully considering the individual differences of children, is conducive to the development of children's personality, courseware of ** let children recognize the diversity of trapezoids, so that children unconsciously understand the characteristics of trapezoids.

Of course, in the design of this lesson, I have not done enough to prepare for it, and in the future teaching, I will carefully study the teaching materials, carefully design, and make the children learn more knowledge in the game.

The trapezoidal lesson plan is designed with the following intentions:

Because the trapezoid is a quadrilateral with and only a set of opposite sides parallel, the concept is relatively abstract, and it is the most difficult kind of plane figure that children need to know. Therefore, kindergarten children only need to understand its characteristics and be able to find the corresponding figures, and there is no need to ask children to describe the characteristics of the trapezoid.

Objectives:

1. Stimulate children's interest in understanding plane graphics and their desire to explore.

2. Develop children's keen observation and abstract generalization skills.

3. Let children basically grasp the characteristics of trapezoids and find out the trapezoids.

The main difficulties of the activity:

1. Activity focus: a preliminary understanding of the characteristics of trapezoids.

2. Difficulties in chaotic reed-based activities: recognize different trapezoids in different positions.

Event Preparation:

**, slides, trapezoidal and rectangular hand-sized, graphic stone paths, small envelopes with various graphics.

Activity process:

1. Introduce the situation and lead to the theme

1. Show the slides of the white rabbit and guide the children to observe what the white rabbit's house is made of.

2. Perceive the characteristics of the trapezoid. (4 corners, 4 sides, 2 sides parallel to each other, different lengths).

3. Comparison between rectangular and trapezoidal shapes.

2. Observe and understand the characteristics of trapezoids and deepen their understanding of trapezoids

1. Show the trapezoids in other parts of the White Rabbit's house, so that children can know the reputation and deepen their understanding of the trapezoid.

2. Show the trapezoidal shape of the slide and let the trapezoidal rotate in different directions to deepen your understanding of the trapezoid.

3. The teacher summarizes again.

3. The game "Looking for the Trapezoid".

1. Show the stone road designed by the white rabbit, so that children can know the graphics in the design draft.

2. Ask the children to help complete the design of the trapezoidal stone road.

3. Children and teachers inspect the trapezoidal gravel road together.

4. Put ** and step on the trapezoidal gravel road to go on an outing.

Activity Reflection:

I designed this activity mainly from children's understanding of flat figures, because the concept of trapezoidal is a group of quadrilaterals whose opposite sides are parallel and the other opposite sides are not parallel is called trapezoid. However, due to the age characteristics of kindergarten children, the concept of trapezoidal is not easy to understand, and children are not required to use language to describe trapezoidal characteristics. I will complete this activity through three parts.

First of all, let the children perceive the diversity of the trapezoid, let the children really understand the trapezoidal through the operation activities, and finally use the game to consolidate this activity. In the activity, the children's enthusiasm is very high, they are willing to participate in the activity, and the interaction is also good. I feel that this goal has been accomplished very well.
