Teaching preparation ** 1. Teacher's preparation: Coursewares, object projector. 2. Students prepare: learning tools, discs, homework papers. ** 4. Teaching process ** #(I) Scenery Introduction 1. ** Create a scenario ** - Show the picture in the information window 1 on page 40 of the textbook (for example, the picture of the green ecological park). Ask: Students, have you been to the green ecological park? Today, I'll take you to take a look. 2. ** Introduction ** - He guided the students to observe the blooming flowers and pointed out the mathematical problems in today's class to explore the green ecological garden. This scene could stimulate the students 'interest in exploring. #(II) Exploring new knowledge 1. ** Observe the scene map, find mathematical information, and ask questions ** - The teacher pointed out that there were pink, yellow, red, and other colors of flowers in the picture, and there were equally many flowers of all three colors, and asked what "equally many" meant (the same number and the same arrangement). - The students were guided to carefully observe the hidden mathematical information in the picture. For example, there were five rows of each color and eight pots in each row. - Based on this information, the students were guided to ask mathematical questions, such as "How many pots of flowers are there in total?" The class also showed the complete examples and asked the students to read the questions. 2. ** Independent analysis, problem solving ** - How many pots of flowers are there in total? This question was used as an example for teaching. - ** Intuitional operation, understanding the relationship between numbers ** - In order to facilitate the analysis, the students were asked to replace the flowers with small round pieces. The three groups of small round pieces represented the flowers of three colors. The students were guided to determine what to calculate first and then what to calculate on the basis of hands-on operation. - ** Exchange and discuss, show the algorithm ** - Invite the students who have the answers to come on stage and use the hands-on process to explain their thoughts. - ** Step-by-step answers ** - First, calculate how many pots there are for each color. The formula is: 5×8 = 40 pots. This step was to multiply the number of pots in each row by the number of rows to obtain the number of pots of a color. - Then, he calculated the total number of pots of flowers of the three colors. The formula was: 40×3 = 120 (pots). This was the total number of pots obtained by multiplying the number of pots of flowers of a color by the type of color. - ** Comprehensive Formula ** - The general formula was: 5×8×3 = 40×3 = 120 (pots). Here, the product of 5×8 was calculated from left to right, then multiplied by 3. - Students could also be guided to think from another perspective. First, find out how many pots there were in a row of flowers of three colors. The formula was: 8×3 = 24 (pots). Then, calculate how many pots there were in total. The formula was: 24×5 = 120 (pots). The comprehensive formula was: 8×3×5 = 24×5 = 120 (pots). #(3) Consolidating Practice 1. For example, in the stamp album, there were three rows of stamps on each page, and each row had four stamps. How many stamps were there in total on the three pages? Let the students do it independently and exchange ideas. 2. The students were given information such as 4 yuan for each shuttlecock and 6 shuttlecocks in a box. #(IV) Class summary 1.

Elementary school mathematics second grade second volume corner understanding
In the second volume of the second grade of elementary school mathematics, the understanding of angles included the following contents: 1. ** The definition and composition of an angle ** - An angle was a geometric figure formed by one or more rays intersecting at a common end point. This common end point was the apex of the angle. The rays that formed the angle were called the sides of the angle. The angle was usually represented by the symbol "". For example, ABC represented the angle ABC. A corner had one apex and two sides. 2. ** Horn classification ** - ** Right angle **: An angle equal to 90 degrees is a right angle. One could use the right angle on a triangular ruler to compare to determine whether a corner was a right angle. - ** Sharp angle **: An angle less than 90 degrees is an acute angle. For example, when the hour hand is at 10, 20, 10, or 110, the angle formed by the minute hand and the hour hand is an acute angle. - ** Obtuse angle **: An angle greater than 90 degrees but less than 180 degrees is an obtuse angle. For example, when the hour hand is at 40, 50, 70, or 80 degrees, the angle formed by the minute hand and the hour hand is an obtuse angle. 3. ** Comparing the sizes of the horns ** - The size of the angle depended on the angle between the two rays. The larger the angle, the larger the angle. When comparing the size of an angle, one could use the overlapping method. First, the two vertexes were aligned, and then one side of the two angles overlapped. Looking at the position of the other side, the corner of the other side on the outside was large, the corner of the other side was the same size, and the corner of the other side on the inside was small. 4. ** Angular measurement and tools ** - The most basic unit of measurement for angles was degrees, which divided a circle into 360 degrees. The tool used to measure the angle was a protractor. The protractor had two inner and outer scale rings, corresponding to 0 degrees and 180 degrees respectively. When using a protractor to measure an angle, the center point of the protractor should be coincided with the apex of the angle, and the 0 degree scale line should be coincided with one side of the angle. Eyes should be aimed at the inner scale circle of the protractor, and the corresponding degree of the other side should be found, which is the size of the angle. At the same time, attention should be paid to the accuracy. Try to choose a suitable protractor or measure the average value many times. 5. ** A corner in life ** - On the clock, the minute hand and hour hand formed different angles at different times. For example, at 30 or 90 hours, the angle formed by the minute hand and hour hand was a right angle; at 3:30 in the afternoon, the angle formed by the minute hand and hour hand was a right angle. 6. ** Corner related teaching activities ** - Students could learn how to recognize and compare the sizes of the horns through folding paper. For example, the teacher would ask the students to prepare a square piece of paper before class. After class, the teacher would first use the pictures in the class to find the corner with the child, and then find the corner in the classroom. When the students had an understanding of the corner, the students would fold a corner themselves, and then try to compare whose corner was bigger. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Elementary school first grade handwritten report second volume mathematics
There were many ways to make and content choices for the second volume of the first-grade mathematics handwritten report. In terms of content, it could include the sorting of mathematical knowledge, such as the abdication of numbers within 20 (this was the knowledge content in the first four units of the second volume of the Beijing Normal University edition), or the understanding of numbers within 100. It could also show the methods of mathematics learning, such as the method of orderly thinking. At the same time, he could incorporate famous mathematicians 'sayings. For example, the famous mathematician Gauss once said,"Mathematics is the science of the universe. It can appear by your side at any time." In terms of aesthetics, colored lead could be used to draw illustrations and color the content section. If he chose colored lead, the erasable-colored lead was a good choice. It had a high color saturation, and it was smooth and difficult to break the lead. Moreover, if he made a mistake, he could easily erase it with an ordinary eraser. It could not only ensure the color of the handwritten report, but also make it easy to modify. The overall layout of the handwritten newspaper had to be cleverly conceived. With bright colors, through hands-on, brain-on, and painting, the handwritten newspaper with distinct personalities was created. The art foundation and knowledge were integrated into one, fully demonstrating the creativity of the students. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
