In the teaching of division, the key was to understand the theory of arithmetic and master the algorithm. Students should take the initiative to explore methods, exchange and display, and experience the exploration process. Teaching should combine schematics to help students think, respect students 'algorithm choices, and also consider how to guide students to break through the dilemma of thinking, design practical exercises, and closely connect old and new knowledge. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Here are some children's songs about mental arithmetic: 1. ** Sweeping the floor, thunder, finger exercise (direct addition and deduction in abacus)** - The abacus was added directly: one to one, two to two, three to three, four to four, five to five, six to six, seven to seven, eight to eight, nine to nine, and the heart remained. - The abacus was reduced: one to one, two to two, three to three, four to four, five to five, six to six, seven to seven, eight to eight, leaving nine, nine to nine. 2. ** Five plus points ** - When the number of beads reached five, the incantation had to be used. When the lower beads were not enough, the upper beads had to be borrowed. One bead was five to four beads, two beads were five to three beads, three beads were five to two beads, and four beads were five to one bead. 3. ** Less than 5 points ** - When the number of beads reached 5, the formula was needed. When the upper beads receded, the lower beads had to be replaced. One above four to five, two above three to five, three above two to five, four above one to five. 4. ** The breakdown of five ** - Take it apart and divide it into points. You have to pay attention to the decomposition of 5. 5 can be divided into several numbers. Take the beads to learn. Minus 1 is minus 5 plus 4, minus 2 is minus 5 plus 3, minus 3 is minus 5 plus 2, minus 4 is minus 5 plus 1. 5. ** One and Two's Pearl Plucking Method ** - The small beads represent the number. Let's move the beads together. If we move one small bead up, it will represent the number 1. If we move two small beads up, it will represent the number 2. 1 is 1, 2 is 2. Move the beads and remember clearly. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Each lesson would be arranged with cheerful and easy-to-remember children's songs based on the knowledge points. Each lesson would use the daily life stories of kindergarten children such as Harry to explain the addition and addition of mixed operations within 20. While the children watched cartoons, they could understand mathematical calculations. Harry Potter and the Sorcerer's Stone was not enough. Everyone, please click to read the novel!

In the teaching of two-digit minus one-digit abdication, there are the following points worthy of reflection: ** 1. Grasping the student's basic knowledge ** 1. ** Using existing knowledge ** - Before the students learned two-digit minus one-digit abdication, they had already mastered the abdication of less than 20, two-digit plus one-digit, and tens, two-digit minus one-digit non-abdication, and tens. In teaching, we should make full use of this existing knowledge and guide students to learn new content through knowledge transfer. For example, when faced with a question like 36 - 8, the student could recall the situation where 6 - 8 was not enough to reduce the number within 20, and then think about how to solve a similar problem in two-digit numbers. 2. ** The impact of differences in knowledge base on teaching ** - There were differences in the degree of mastery of previous knowledge between students. Some students did not have a solid grasp of abdication within 20, which would lead to difficulties when calculating two-digit minus one-digit abdication. For example, the calculation speed was slow and error-prone. This requires teachers to pay attention to this difference in the teaching process and provide targeted guidance to these students. ** 2. Teaching methods ** 1. ** Diverse algorithms and understanding of arithmetic ** - In teaching, it is important to encourage students to calculate in a variety of ways. For example, for 36 - 8, students might have 36 - 6 - 2 = 28, divide 36 into 20 and 16, calculate 16 - 8 = 8, then 20+8 = 28, or divide 36 into 10 and 26, calculate 10 - 8 = 2, then 26 + 2 = 28, etc. However, in this process, although there were various algorithms, students might not be able to express the algorithm clearly, especially when it came to middle and lower physiological solutions. Teachers needed to guide students to explore various algorithms, but at the same time, they needed to pay more attention to letting students understand the calculations behind each algorithm, such as the meaning of borrowing. 2. ** Operation and Practice Section ** - Placing sticks was an effective way to help students understand arithmetic. However, there might be problems in practice. For example, the teacher did not let the students prepare the learning tools (sticks) in advance, and did not let the students count the sticks in advance, which led to the waste of time in the classroom. Moreover, when the students placed the sticks, some teachers only asked the students to talk about the process of placing the sticks, but ignored the practical process of letting the students go to the stage to show how to take 8 sticks out of 36 sticks. This was not conducive to the students 'in-depth understanding of mathematics. 3. ** Teaching Quick Calculation Skills ** - Subtracting a two-digit number from a one-digit number had a quick calculation trick, such as adding 1 when minus 9, adding 2 when minus 8, and so on. However, if one only focused on imparting quick calculation skills in teaching, and the students did not understand its essence (the essence was to break the ten methods), it might cause the students to memorize it mechanically and not be able to use it flexibly. The teacher should emphasize the connection between speed calculation and arithmetic while explaining the skill. ** 3. Cultivating students 'abilities ** 1. ** Cultivation of the ability to express oneself ** - In the teaching process, we should pay attention to cultivating students 'ability to express themselves. Students could only clearly describe the calculation method and process after they understood the calculation theory. For example, in the calculation process of 36 - 8, students should be allowed to explain the calculation process more often. This would help them think clearly and allow teachers to better understand the students 'mastery. 2. ** Cultivating Awareness of Independent Exploration and optimization of algorithms ** - It was necessary to guide students to carry out independent and exploratory learning and cultivate their good learning habits. After the students explored a variety of algorithms, the teacher should organize the students to compare these algorithms, guide the students to optimize the calculation method, and enhance the awareness of the optimization algorithm. For example, students could compare the difference in calculation speed and accuracy of different algorithms to choose the algorithm that was more suitable for them. ** 4. Pay attention to students of different levels ** - In classroom teaching, not only should we pay attention to cultivating students 'creative expression ability, but we should also pay attention to the learning mastery of the backward students. Teachers could not only focus on some of the positive students, but should focus on every student, discover and correct the students 'mistakes in time, so that every student could experience the joy of success, and ensure that all students could better master the mental arithmetic method of two-digit minus one-digit abdication. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The following is a case study of a sixth-grade primary school student's mental arithmetic ability: ** I. Problem and Cause Analysis ** 1. ** Problem Presented ** - In the investigation of the mental arithmetic ability of 82 sixth grade students, only 30 of them were tested correctly. There were 25 people who got one question wrong, 14 people who got two questions wrong, 5 people who got three questions wrong, 3 people who got five questions wrong, and 4 people who got 10 questions or more wrong. 2. ** Cause Analysis ** - [Temporary Memory Loss: Primary school students are prone to making various mistakes when doing mental arithmetic. There are many reasons.] During the process of mental calculation, there might be a temporary memory loss that would affect the results of the calculation. ** II. Modification measures ** 1. ** From basics to specifics ** - ** Sorting out the idea of mixed fraction operations **: For mixed fraction multiplication and division operations without parenthesis, you can calculate them step by step from left to right, or you can directly convert the scores into continuous multiplication and calculate the scores at the same time. At the same time, you should review the number pairs that are easy to forget the common factor, such as 14 and 21, 28 and 35 (the common factor is 7), 13 and 26, 26 and 39 (the common factor is 13), etc., to deepen the student's impression of these numbers. 2. ** Pay attention to forming good habits ** - [Writing must be correct: Teachers must set an example by writing on the blackboard and marking symbols.] Demonstrate during the board performance, seriously guide the students 'practice, train repeatedly, and persist for a long time. - ** Carefully examine the question **: Students should examine the question carefully. Before calculating, they should first find the characteristics of the numbers and symbols in the question, clarify the relationship between them, and then choose a reasonable calculation method to calculate. Through these teaching improvement measures, the sixth grade students 'mental arithmetic ability could be improved in many ways, reducing the error rate of mental arithmetic, and improving the accuracy and speed of mental arithmetic. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
