Multiplication, problem solving, reflection on teaching, third gradeThe following are some possible aspects of reflection on third-year multiplication problem solving:
** 1. Knowledge and Skills **
1. ** Understanding and application of algorithms **
- When teaching multiplication to solve problems, one had to pay attention to the depth of the student's understanding of the meaning of multiplication. For example, in a two-step multiplication application question, could the student accurately determine the steps of the multiplication operation based on the numerical relationship in the question? For example, each ping pong ball is 2 yuan, and there are 5 ping pong balls in a bag. Please ask for the total price of 6 bags of ping pong balls. Students need to understand that the price of a bag is calculated by "the number of bags x the price of each bag", and then multiplied by the number of bags to get the total price, or the total number of table tennis balls is first calculated and then multiplied by the unit price to get the total price. If students had problems with this, it might reflect a lack of familiarity with the concept of multiplication in practical situations.
- For the calculation of three-digit multiplication by two-digit multiplication, he had to consider whether the students could successfully transfer the calculation theory and algorithm of two-digit multiplication by two-digit. During the teaching process, some students might find that although they could calculate the results mechanically according to the calculation steps, they were not clear about what each result represented and why they were calculated. This would require a stronger explanation of mathematics in the teaching. For example, by letting the students understand it in light of specific situations, such as calculating Uncle Li's train journey (speed x time), so that the students could understand the meaning of each digit multiplication and the principle of carry.
2. ** Calculation accuracy **
- A third year student might make mistakes in multiplication because they were not familiar with the multiplication formula. For example, in some simple multiplication calculations, such as 43×30, if the student memorized the chant wrongly or made a mistake in addition, the result would be wrong. In the reflection of teaching, he had to consider whether he had strengthened the memory of the multiplication formula and the practice of simple mental arithmetic in his daily teaching. At the same time, he had to think about how to better let the students master the error-prone areas in the calculation of multiplication, such as digital alignment, carry, etc.
3. ** Problem solving strategies are diverse **
- Students should be encouraged to use different strategies in solving multiplication problems. For example, in the two-step multiplication problem, some students might start from the relationship between unit price and quantity, while some students might start from the relationship between total quantity and partial quantity. Teachers should reflect on whether they gave students enough space to explore different solution methods in the classroom, and whether they should guide students to compare and analyze different solution strategies so that students could better understand the application of multiplication in different situations.
** 2. Teaching methods and processes **
1. ** The effectiveness of situation creation **
- If you create a situation related to multiplication in the teaching, such as shopping, travel, etc., to lead to multiplication to solve the problem, you have to reflect on whether these situations really help students understand the meaning and application of multiplication. For example, whether the situation was too complicated to distract the student from the multiplication relationship, or whether the situation was out of touch with the student's life, making it difficult for the student to connect what he had learned with the situation.
2. ** Students 'independent learning and cooperative exchange **
- They had to consider whether they should give students enough time to study independently during the teaching process. For example, when exploring the method of solving multiplication problems, did the students have enough time to think about the problem independently and try different ways of solving the problem? At the same time, for the group cooperation and exchange session, they had to reflect on whether the group division was reasonable and whether every student could participate in the discussion. After the group exchange, the whole class exchange session could fully display the results of the students 'thinking, so that different solution methods could be shared and discussed.
3. ** Practice and feedback **
- Whether the practice design in the teaching was reasonable and whether it covered different types of multiplication problems. For example, whether there were enough basic exercises to consolidate the multiplication calculation skills, whether there were extended exercises to develop the students 'ability to solve complex multiplication problems. During the post-practice feedback session, whether or not they could discover the students 'mistakes in time and provide targeted explanations. For example, when displaying students 'wrong homework, could they guide the students to accurately find the cause of the error and correct it, while letting other students learn from it.
** 3. Students 'learning attitudes and habits **
1. ** Learning enthusiasm **
- He had to reflect on the enthusiasm of the students in the process of solving problems by multiplication. If the student participation was not high, it might be because the teaching method was not attractive enough, or the difficulty of the questions was too high or too low. For example, if the questions were too simple, the students would not find them challenging. If the questions were too difficult, the students would feel afraid of the difficulties, which would affect their enthusiasm for learning.
2. ** Cultivating study habits **
- Whether or not they pay attention to cultivating students 'good study habits in teaching, such as the habit of carefully examining questions. In the multiplication problem solving, whether the student could accurately extract the key information from the question and determine whether it was a one-step multiplication or a two-step multiplication. At the same time, when students shared their ideas and methods in class, they were encouraged to express them in a complete mathematical language to cultivate students 'rigorous thinking habits. If the students did not perform well in these areas, they had to think about how to improve them in subsequent teaching.

Celadon cultural relics collectionThe collection of celadon cultural relics had many meanings and values.
From a historical point of view, celadon had a long history of development, and its evolution reflected the level of porcelain making technology in different periods. For example, primitive celadon appeared in the Shang and Zhou Dynasties, mature celadon was successfully produced in the Eastern Han Dynasty, celadon kiln factories increased in the northern and southern dynasties during the Three Kingdoms, Jin and Southern Dynasties, celadon was still mainstream in the prosperous Tang Dynasty, and reached its peak in the Song Dynasty. Although the Yuan, Ming and Qing Dynasties were not as strong as before, they still had a place in the porcelain market.
In terms of collection value, some celadon of the Song Dynasty, such as the Northern Song Ru kiln celadon and the Southern Song Longquan kiln celadon, were regarded as the pinnacle of ceramic history and were deeply loved by collectors. Some rare shapes, unique glaze colors, and exquisite craftsmanship would increase the collection value of celadon relics. For example, the string-patterned plum vase of Longquan Kiln in Southern Song Dynasty, its shape, glaze color and decorative beauty reflected the highest realm of Song porcelain aesthetics; the lotus flower cup of Longquan Kiln in Southern Song Dynasty was rare in the world; Longquan Kiln in Southern Song Dynasty could convey the taste of palace porcelain; Longquan flower plug in Southern Song Dynasty had thick glaze layer and strong jade texture, etc. Among the Longquan kiln porcelain of the Yuan Dynasty, such as the lotus leaf lid jar, which had strong characteristics of the era, also attracted much attention. Its value depended on factors such as glaze color, shape and craftsmanship. For example, plum green glaze color was relatively expensive.
For collectors, it was also important to know about celadon kilns. For example, the Yaozhou kiln was founded in the Tang Dynasty. The Huangbao kiln was innovative and mature in the Five Dynasties. It flourished in the Song Dynasty and continued to develop in the Jin Dynasty. At the end of the Jin Dynasty, the Yuan Dynasty declined day by day and stopped burning in the middle of the Ming Dynasty. The Chenlu kiln was the latest to be founded, but it was the largest and lasted the longest. The Ming and Qing Dynasties were its heyday. Yaozhou kiln in the Northern Song Dynasty carved flowers, picking flowers mature technology, printing technology also rose, its products are diverse.
In addition, the unearthed cultural relics were of great significance to the collection value and research of celadon. For example, the green-glazed porcelain of Yaozhou kiln unearthed from the tomb of the Meng family of the Northern Song Dynasty in Xi'an, Shaanxi Province, provided important material information for the study of the types of Yaozhou kiln ware, the firing process and the development of porcelain industry in the Northern Song Dynasty.
In the collector's market, the price varied according to the specific item. For example, the banana leaf folding bowl of the Ming Dynasty or above would cost about 3680 yuan.
