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

Dementor Hero Battlefield Skills
Dementors had five skills in Battlefield of Heroes: 1. [Laser Beam]: This is a powerful control skill that has a straight line attack range. Once hit, the enemy will enter a short stun state, unable to perform any operations. At this time, the dementor or its teammates can use high-frequency skills to deal damage. The order of priority was: damage> tank> warrior. Before using it, one had to predict the enemy's position to increase the hit rate and maximize the skill's damage. 2. [Recharge: A support skill.] When this skill is activated, the dementor's movement speed will be increased by 100% for 5 seconds. It could be used to chase down enemies with low health to prevent them from escaping, and it could also be used to hurry. It had special significance in actual combat. 3. [Retractable Light Claw]: A control skill. Its function is to extend the light claw to pull the enemy from afar to its side. Common uses included pulling the enemy's fragile heroes to their own camp to focus fire and destroy them, or as a chasing skill. It could also form a small combo with the laser beam. When the enemy was stunned by the laser beam, it could quickly use the retracting claw to pull the enemy to its side (the connection speed needed was fast enough). 4. [Mechanical Whirlwind]: This is a close-range attack skill. After activation, the dementor will spin on its own, causing continuous damage to surrounding enemies. Before using it, one had to ensure the surrounding situation. Generally, it was activated after the enemy members were controlled by the camp. Although the damage was high, it was also dangerous. 5. [Death Leap] was a skill that could both support and deal damage. It could be called a group control skill and was also a dementor's ultimate skill. After using it, it can deal huge damage to surrounding enemies and slow them down. The location of the skill is more particular. It is usually used in a team battle to maximize its power. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Do I need to fill in the data for the biology operation experiment in the middle school entrance examination? Why?
In the biological operation experiment of the middle school entrance examination, data may need to be filled in for the following reasons: The recording and processing of experimental data is one of the assessment contents. For example, in some experiments, it might involve the quantitative recording of experimental phenomena, such as the number and size of cells in an experiment to observe cell structure, or the data changes of relevant biological indicators in an experiment to explore the effects of certain factors on organisms.

Life Koi composition 800 words
Life Koi In the long river of life, we all yearn to be the lucky koi, to leap over many difficulties and reach the other side of our dreams. In traditional culture, koi symbolized good luck and good fortune. In the context of life, it represented our yearning and relentless pursuit for a better life. A koi in life must first have the blessing of dreams. Just like how the little carp Bubbles dreamed of jumping over the Dragon Gate, the Dragon Gate was the ideal holy land in its heart. Each of us also has our own "dragon gate". It may be a favorite job, a happy marriage, or a noble ideal pursuit. Dreams give us direction, so that we won't get lost in the vast sea of life. However, the road to dreams was never smooth sailing, just like how a carp had to face a turbulent waterfall and many difficulties when it jumped over the dragon gate. In the process of pursuing our dreams, we will encounter doubts from the outside world, face the limitations of our own abilities, and even encounter some unpredictable setbacks. In the face of difficulties, we need to have the courage and perseverance of a koi fish. While the carp was going against the current and rushing towards the Dragon Gate, many of its companions were knocked down by the waterfall and smashed into pieces by the rocks, but there were always some who could hold on. They did not retreat because of the danger ahead. Instead, they charged at their target again and again. We should do the same in our lives. When we are denied by the world, when we encounter seemingly insurmountable obstacles, we cannot give up easily. Juexin in Ba Jin's " Home " was struck from the bright dream by Grandpa Gao's words, but he should have risen from the predicament like a koi fish, instead of retreating. We need to move forward courageously towards the dragon gate of our dreams with firm faith and tenacious perseverance. Becoming a koi fish in life also required a positive attitude. The koi in real life were colorful. They swam elegantly in the water, giving people a positive feeling. In the journey of life, we should also maintain an optimistic and positive attitude. Even if they encountered setbacks, even if there were voices of opposition around them, they had to be like those koi swimming against the current, filled with hope. If the "Buddhist" attitude of life is treated correctly, it can allow us to be calm in the face of setbacks, but it is definitely not a passive retreat. We should take a positive view of the gains and losses in life, not be defeated by a moment of failure, but treat every experience as an opportunity to grow. Moreover, the koi fish did not walk alone. During the process of the carp school rushing to the Dragon Gate, they were a whole, encouraging and supporting each other. In our lives, family and friends are our companions. They helped us when we were in trouble and gave us advice when we were confused. We must also learn to cherish the people around us, grow with them, and pursue our dreams together. Life was like a carp. If one wanted to become a carp that leaped over the dragon gate, one needed to have a dream, rely on courage and perseverance, maintain a positive attitude, and work hand in hand with the people around them. Only in this way can we swim in the long river of life and finally leap over our own dragon gate to reap success and happiness.
