Let the students review the derivation process of the area of a hexagon and clarify the derivation of the formula for the area of a hexagon. 2. Guide the students to deduce the area formula of other hexagons from the area formula of a certain hexagon, and understand the mutual transformation relationship between the areas of the graphs. 3. To let the students understand the application of the transformation method in daily life, and to experience the joy of mathematics in daily life. ##2. Difficulties in Teaching 1. ** Main point ** - Through the revision, the students could clearly grasp the derivation process of the formula for the area of a hexagon. - With the help of the team, they could explore the principles behind the formula derivation. 2. ** Difficulty ** - Through the real-life examples of area calculation, students could deeply understand the practical significance of mathematics in life. ##3. Prepare the teaching materials Pre-class review sheet, exploration sheet, tablet, tangram, exercise sheet. ##4. Teaching process ###(1) Review 1. introduce a topic - "Students," the teacher said."Today, let's review the area of a hexagon." "We've learned about area before. What's the use of area?" He guided the students to answer that the area was used to represent the size of the figure. - "Then, which shapes have we studied?" he asked. Ask the students to recall and answer the questions of a rectangular shape, a square shape, a quadrilateral shape, a triangle shape, a echelon shape, a combination shape, etc. 2. A Review of the Derivation of the Rectangle Area Formula - The teacher asked,"Who still remembers the area formula of a rectangular shape?" After the students answered that the area of a rectangular shape = length x width, they played a small video to show the derivation process of the rectangular area formula, emphasizing the idea of simple calculation with the help of multiplication. 3. A Review of the Derivation of the Square Area Formula - Show a square with a side length a and ask the area formula. To guide the students to understand the area formula of a square (the area of a square = the length of a side x the length of a side) was derived by converting the area of a square into the area of a rectangular shape with equal length and width. 4. A Review of Derivation of Area Formula for Parallel Quadrangle, Triangle and Trapezoid - Please report according to the pre-class review sheet. As for the quadrilateral, the students were guided to say that the area formula could be derived by transforming the quadrilateral into a rectangular shape; as for the triangle, the area formula could be derived by transforming it into a quadrilateral; and the area formula could be derived by transforming a echelon into a quadrilateral, similar to a triangle. During the student's report, the teacher would paste the corresponding picture name on the blackboard to strengthen the memory. ###(2) New Knowledge 1. He guided the students to think,"We found that the area of a triangle and a echelon is usually converted into the area of a quadrilateral. Can it be converted into the area of a rectangular?" To stimulate the students 'interest in exploring the conversion relationship between the formulas for the area of a hexagon. 2. Teaching the Area of Combined Figures - He asked,"For example, when calculating the area of the living room (composite graphics), what methods can you use to help with the calculation?" He guided the students to open the corresponding page of the book to read the contents of the textbook and supplement the pre-reading questions. - Organizing group communication: Let the students share their calculation methods in the group. The group leader is responsible for organizing the sharing and complementing. - Group representative report: Please invite a group representative to come on stage to exchange the group's calculation method. The rest of the students will listen carefully, think actively, and make additional speeches. This paper summarized the area calculation method of the composite graph, including estimation, division, addition, cutting and other methods to transform the composite graph into a regular graph. The area of the regular graph was calculated separately, and then the area of the original composite graph was obtained through addition and addition. In this process, the students could experience the transformation thought. - Finally, let the students use the methods they have learned to complete the corresponding exercises, such as the practice on page 89 of the book. ###(3) Class summary 1. Ask the students: "Today, we have reviewed the area of a hexagon. What did you learn?" The students were guided to review the derivation process of the area formula of the hexagon, the conversion relationship between the area formulas of different figures, and the calculation method of the area of the combined figures. 2. It emphasized the application of mathematical knowledge in life and the importance of transforming ideas. Students were encouraged to flexibly use the knowledge they learned to solve practical problems in their future studies. Read more exciting novels for free

Here are some ways to take portraits in Dream Garden: 1. * * In terms of composition ** - [Using a frame to compose a picture: There are many frame objects in the garden that can be used, such as door frames, window frames, or using flowers to create a natural frame. Placing the characters in the frame can make the primary and secondary clear, allowing the viewer to naturally focus on the characters.] - * * Horizontal Screen and Three-Divided Method **: If you want to capture the image of the MV, you can use the horizontal screen to shoot the bust of the character. He turned on the cell phone's grid function and arranged the characters on the three-point line of the screen. He handled the relationship between the characters and the environment to create a dreamy and beautiful atmosphere. - * * The characters are arranged below the flowers **: If you want to highlight the spectacular momentum of the garden, you can use a large scene to shoot, so that the flower sea element takes up one-fifth or one-fourth of the picture, and it is arranged at the top of the picture. The audience's line of sight will move down to the main body of the character along with the position of the flowers. - * * White space in front of the line of sight **: When shooting a garden portrait, it is necessary to leave white space in front of the person's line of sight. This can extend the meaning of the picture, arouse the audience's curiosity about the direction of the model's gaze, and also add imagination to the photo story. 2. * * In terms of shooting angle ** - [Upper-view shot: When there are too many people in the garden and it is not easy to take a shot, the person can stand on the garden bridge and the photographer can take a low-angle up-view shot from below. In this way, only the sea of flowers and the person are in the picture, which is simple and the main body is prominent.] - * * High camera angle **: You can raise the camera angle to shoot from above, such as the character picking up petals, the character propping up the ground with his hands and lifting his hair, etc. You can also use the flower branch as the background to increase the atmosphere. 3. * * Character Postures ** - * * Leaning on the body curve **: In 2D portrait photography, in order to enhance the three-dimensional effect of the portrait, you can rely on the movement of the limbs or leaning on the body. For example, leaning against the car in the garden with the feet placed in front and back to show the body curve. - * * Standing sideways to shoot the whole body **: When shooting a big scene, the character will stand sideways on the flower path to shoot, using the extension and guidance of the path to guide the audience's attention to the character. - * * Walk on the stairs while taking photos **: If there are stairs in the garden, when taking full-body photos, let the character walk on the stairs while taking photos. The line of sight should avoid looking at the camera and pay more attention to the surrounding garden scenery to make it look casual. 4. * * Picture effects ** - * * Foreground Blur **: Choose a few flowers as the image's background, and use a long focal length or large aperture to blur the background, making the image appear dreamy and illusory, making the overall picture more romantic and atmospheric. - * * Multiple exposure (Canon camera)**: Canon camera's multiple exposure function can be automatically synthesized in the camera. For example, in an open area, one could take a selfie from the front and then take a scene (such as a building). The two would be combined to produce a multi-exposure photo. The number of shots could be set according to the needs (up to nine). 5. * * Other aspects ** - * * Using Scene Elements **: Use a hanging flower branch as the front. The flower branch is placed in the upper right corner of the picture, and the character is in the lower left corner. It can balance the picture and highlight the character's emotions. He could also make use of the fallen petals in the garden, such as squatting down to pick up the petals and putting them in his mouth. - * * Color adjustment (post-production)**: If the camera allows color adjustment, color adjustment settings such as brightness +8, contrast +4, hue +7, sharpness +8, saturation +10, highlight + blue can make the photo more dreamy. - * * Lighting Equipment (Night Scene)**: When shooting portraits at Dream Garden at night, you can use a 100-Watt high-power lighting device like the Zhiyun CX100 to improve the image effect while ensuring its maneuverability. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
To identify the anamorphosis of English words, one could start from the following aspects: ** 1. Judging by the meaning of the words ** 1. ** Denying the meaning, transforming ** - Many words became negative by adding a specific precondition, such as dis -, im -, in -, ir -, is-, non -, un -, and so on. For example, agree becomes disagree, patient becomes impatient, active becomes inactive, and so on. 2. ** Part of speech conversion and word meaning association ** - Some words could change their word form by changing the ending of the word, and the meaning of the word would be related accordingly. For example, beauty became beautiful; the verb was followed by a- ment, - tion, - sion, etc., which became a formal. Admit became admission;apply became application. ** 2. According to the pronunciation rules ** 1. ** Distortion of regular pronunciation ** - In some regular word transformations, the pronunciation would follow certain rules. For example, when an adjective ending in "y" becomes an adverb,"y" becomes "i" and then- ly, just as "easy" becomes "easily". 2. ** Vowel pronunciation changes ** - The pronunciation of the syllable may change in different variations of the word. For example, man (singular), men (plurals), the syllable "a" became "e", and the pronunciation also changed. ** 3. Judging from the Spelling Rules of Words ** 1. ** Tense Distortion of Regular Verbs ** - For regular verb forms, the past tense and past tense followed certain rules. For example, adding- ed to the original form of a common verb meant the past tense and past tense, such as work, worked. 2. ** Memories of special transformations ** - There were also some special word transformations that needed to be memorized separately. For example, the transformation of lie was lied (past tense), lied (past verb); the transformation of lie was lay (past tense), lain (past verb); and the transformation of lay (lay eggs) was laid (past tense), laid (past verb). He could remember these special transformations through chants and other methods. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
