Two-digit minus two-digit teaching plan and reflection
#1. Teaching objectives 1. Let the children in the middle class understand the concept of two-digit minus two-digit in the game or in specific situations. 2. Through the operation of visual teaching aids, the children's mathematical thinking and hands-on ability were cultivated. #2. Difficulties in Teaching 1. ** Main point ** - Help children understand the calculation process of two-digit minus two-digit. - To guide children to master simple calculation methods. 2. ** Difficulty ** - Let the child understand the concept of borrowing (if it involves abdication and substitution). - How to present abstract mathematical operations in an easy-to-understand way according to the child's cognitive level. #3. Teaching Method 1. Game Teaching Method: Use games to stimulate children's interest in learning. 2. Visual demonstration method: use teaching aids to perform visual demonstration, which is easy for children to understand. #4. Teaching process ##(I) Introduction 1. create situations - You could set up a "Ministores" scenario and display some products with price tags. The price was in two digits, such as a toy car for 35 yuan, a doll for 23 yuan, and so on. 2. raise a question - Ask the child,"If we use the money of a 35-yuan toy car to buy a 23-yuan doll, how much money is left?" This led to the topic of two-digit minus two-digit. ##(2) Teaching 1. visual demonstration - Using the stick as a teaching aid. For example, to calculate 35 - 23, first take out 3 bundles (10 sticks per bundle) and 5 small sticks to represent 35, then take 2 bundles and 3 small sticks from inside. Let the child see the number of sticks left and guide the child to count the remaining 12 sticks, which is 35 - 23 = 12. - If it involved abdication, such as 42 - 35. Similarly, he took out 4 bundles and 2 small sticks to represent 42. When reducing, 2 sticks minus 5 sticks was not enough. At this time, he needed to borrow 1 bundle from the 4 bundles and split it into 10 sticks, which added up to 12 sticks. Then, he would deduct 5 sticks, leaving 7 sticks. Then, he would deduct 3 bundles, leaving 7 sticks, which was 42 - 35 = 7. In this process, the focus was on explaining the concept of borrowing. For example, to break a bundle of sticks apart was to borrow a ten from ten to become ten ones. 2. Game Consolidating - The game of buying and selling began. Divide the children into small groups. Each group has some simulated currency (marked with a two-digit amount) and goods (marked with a price). Let the children trade with each other and calculate the change (two digits minus two digits). The teacher observed and guided the children, encouraging them to use sticks or their own methods to calculate. ##(3) Teaching summary 1. Review Knowledge Points - Review the calculation of two-digit minus two-digit with the child today and let the child tell how he calculated it. 2. Praise and encourage - Praise and encourage children's positive performance and correct calculations in class to enhance their self-confidence. #V. Reflection on Teaching 1. ** Success ** - Through the game and visual demonstration, the participation of the children was high, and they had a preliminary understanding of the concept and calculation of two-digit minus two-digit. For example, in the "Ministores" situation and the "buying and selling game", the children showed great interest and actively calculated. - The use of the stick teaching aid was very effective. It could transform abstract mathematical operations into intuitive operations and help children better understand difficult concepts such as borrowing. 2. ** Inadequacies ** - In the process of teaching, some children might have some difficulty understanding the concept of borrowing due to differences in cognitive level. In the future teaching, more exercises and more detailed explanations should be designed for these children. - In the game segment, some children might pay too much attention to the game itself and ignore the learning purpose of calculation. Next time, he could adjust the rules of the game to emphasize the importance of calculation. 3. ** Modification measures ** - For children who had difficulty understanding, they could design some special practice cards with simple two-digit minus two-digit questions on them. They could also be accompanied by small stick diagrams for children to practice and understand repeatedly. - Adding more guidance and questioning in the game, such as in the "business game", when the child is calculating, the teacher can ask the child at the right time,"Why do you calculate like this?" He guided the child to think about the calculation process, not just the result. Read more exciting novels for free

Is it easy for junior high school students to take the geography and biology exam?
For junior high school students, the learning situation of geography and biology was somewhat related to the situation of high school exams, but there were also many differences. In junior high school, geography and biology were relatively basic, and the emphasis was on imparting basic knowledge and simple application. If the results of geography and biology in junior high school were good, it meant that they had a certain advantage in mastering basic knowledge, memory ability, and basic understanding of these two subjects. However, the difficulty of high school geography and biology had increased significantly. The geography knowledge system in high school was even more extensive, including natural geography, human geography, regional geography, and many other aspects. This required stronger logical thinking ability, practical ability, and comprehensive application of knowledge. For example, high school geography emphasized the combination of theory and practice. It required theoretical knowledge to be applied to real-life scenarios, such as analyzing urban planning and industrial layout of a certain area. The knowledge involved was broader and deeper. High school biology was a deeper level of learning on the basis of junior high school. The content of the study included cell biology, genetics, ecology, and many other complex fields. High school biology required strong logical thinking and experimental operation skills. It was more difficult to understand some abstract concepts, such as gene expression and regulation. Moreover, the links between the knowledge points of high school biology were more closely and complicated, and the systematic mastery of knowledge was more demanding. Therefore, even if the results of geography and biology in junior high school were good, it could not be directly inferred that these two subjects would be easy to test in high school. High school students needed to put in more effort and master the methods suitable for high school to obtain good results in the exam. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Ministry of War, Kyokuke, anime plot introduction
In the anime " The Unlimited Kyusuke of the Ministry of War," the main character was the leader of Pandora, a superpower criminal organization. The tone of the story seemed to be stable, but there was a hidden mystery. Kyusuke was born to an esper researcher's father and an esper's mother. His mother died because of his father's experiments, and his father later died of illness. He was entrusted to Baron Reiki's family for adoption. He had once joined the Army's Superhuman Special Forces, and was betrayed and shot by someone he trusted at the end of the war. When he was dying, his superpowers went berserk and he survived as a compound ability user. After that, he hated ordinary people and took revenge. In terms of the plot, the beginning was more exciting. The main character's ability value was extremely high, and the battle scene was overwhelming. After various characters appeared in the middle, the creativity of the plot quickly disappeared. Other than chatting and fighting similar to Sakamoto style, there was no new content. The introduction of the story and the discussion of revenge lowered the quality of the work. The main character in the story was powerful, and the battle scene was cool. Not only did he know how to fight, but he also knew how to scheme. The plot of his recruitment of partners was puzzling. The importance of partners in the play was low and their abilities were not fully displayed. The protagonist would sometimes be given an unreasonable " halo " when facing difficulties, and the way the protagonist chose to take revenge at the end of the story was rather abrupt, which was inconsistent with the concept of " kill " that he had been shouting before. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
