A good lesson plan can also reflect the teacher's degree of care. The following is a lesson plan about the first lesson of eighth grade mathematics, which I collected and arranged for you. Welcome to read!
1 class, the first lesson of eighth grade mathematics, we will walk into the wonderful world of junior high school mathematics together, where there is a brand-new "algebraic" world-expanding number field, wonderful letters representing numbers, powerful equations, inequalities and moving functions; There is a world of "graphics"-we will cut, fold, translate and rotate together, and discover the properties of graphics in the operation experiment. Here, we will also swim in the world of "data" together, learn to get information from graphics, and use the learned probability and statistical knowledge to solve practical problems in life ... Here, mathematics will continuously broaden our horizons, change our way of thinking, let our mind's eyes cross infinite time, and let our mind's hands reach endless space.
Philosopher Bacon said, "Reading poetry makes one witty, reading history makes one wise, learning logic makes one careful, learning philosophy makes one eloquent, and learning mathematics makes one wise ..."
1. Why do you study math?
Mathematics is a tool subject. ※
Mathematics is the foundation of physics, chemistry and other disciplines. It has been said that physicists must be mathematicians, and mathematicians are not necessarily physicists. This shows the value of mathematics.
Life is inseparable from mathematics. ※
Everything from market shopping to rocket launching satellites is inseparable from mathematics. Another example is why wheels are round.
Marx: "Only when a science successfully applies mathematics can it be considered as a truly perfect step." .
Mathematics makes people smart. ※
Some people vividly call mathematics gymnastics of thinking. Specific examples are given to test some mathematical thinking methods and ways. Story 1: It is said that chess was invented by a prime minister in ancient India. The king admired his invention and asked his prime minister what reward he wanted. The clever Zaixiang said, "What I want is to start with a millet (yes, it is 1 grain, not 1 two, nor 1 catty). On this chessboard with 64 squares, the first square puts 1 grain, the second square puts 2 grains, the third square puts 4 grains, that is, every next square puts twice as many grains, … and so on until the 64 squares on the chessboard are filled. This is what I want in return. " The king felt that the Prime Minister didn't want much, so he asked for a reward according to the Prime Minister's request. But later, it was found that even if all the millet in the country was smashed, it would not be enough.
Story 2: There was a king in ancient Greece who tried to execute a group of prisoners. At that time, there were two ways to execute prisoners: one was beheading, and the other was hanging by a rope. In order to show his cleverness, he made a rule: you can say whatever you want, and if it is true, you will be hanged; If it's a lie, kill your head. Among these prisoners, there is a very clever man. When it was his turn to speak, he cleverly said to the king, "I'm going to be beheaded!" " The king was embarrassed: if his head was really cut off, then he was telling the truth, and if he told the truth, he would be hanged; But if you want to hang him, then what he said about "beheading me" will become a lie, and the lie will be beheaded. What he said is neither true nor false, so he can neither be hanged nor beheaded. The king had to wave and say, "Then he has to live. "The prisoner saved himself by his own ingenuity.
2. How to learn math well?
The most important thing in learning mathematics is to be good at thinking. Learning the working methods of bees can not only collect honey, but also make honey. ※. Learning mathematics should be serious, patient and confident. You should have good habits and stick to them in learning mathematics. ※. ※.
Habit 1: preview before class and stick to it.
Preview before class can not only cultivate our self-study ability, but also make our learning progress ahead of the teacher, so that we can focus on our unclear problems in class. It should be noted here: after previewing the textbook, you need to do some related exercises, so that you can not only test the effect of your preview, but also find your own problems. PS: The biggest obstacle to preview before class is that you can't stick to it for a long time.
Habit 2: Prepare well before class.
There are only 40 minutes in the classroom now. If you are not careful, time will run away without a trace. Therefore, we should cherish 40 minutes in class. In order to get more benefits in the 40 minutes in class, you must be prepared for math before class.
1, prepare books and stationery.
2. Prepare the relevant materials required by the teacher.
3. Adjust your state of mind, eliminate external interference, and welcome the study of mathematics classroom with a pleasant mood.
Habit 3: Classroom learning should be efficient.
The efficiency of classroom learning is very important. If we lose the main array of learning, then the efficiency of learning is out of the question. How to improve our classroom efficiency: first, we should concentrate in class; The second is to start work. Only when you start writing and calculating can you motivate yourself to use your brain and find your own problems. Thirdly, in the study of classroom discussion, we should actively express our opinions and communicate with our classmates constantly, which is very beneficial to the cultivation of our thinking ability.
PS: Don't gossip with classmates at the next table or you won't rule out interference.
Habit 4: Take notes skillfully and work hard.
First understand what the teacher said in class, and then write down several key steps in the process of answering complex or difficult questions, leaving blank. After class, you will have careful time to finish your notes. If your notes are difficult to complete, it means that you didn't understand in class, so you must seize this opportunity to understand. Some simple notes can be written directly in the book. Remember never to take notes in class and ignore the teacher's explanation and analysis.
PS: Taking notes without reviewing equals not taking notes!
Habit 5: Finish homework with high quality.
Homework is closely related to the learning content of the day, so you should set high demands on yourself and strive for the correct rate of 100%. At the same time, strive to write neatly and standardize, and the mistakes in the homework should not be underestimated and corrected in time. Finish your homework by yourself, don't ask your classmates, parents and teachers easily, but use your brain more and cultivate your good habit of using your brain! When writing homework, you should achieve the effect of consolidating the learning content of the day.
Habit 6: Review and consolidate constant memory.
"Learning from time to time" and "reviewing the old and learning the new" remind us to take the initiative to review and consolidate frequently. To sum up what you have learned, we should connect the relevant knowledge into a line and form a system. Summarize the common laws and methods of solving problems, draw inferences from others and remember some common conclusions.
Habit 7: Independent expansion platform is high.
"There is no end to learning". We should constantly expand our learning, and the progress of self-study is always in school.
In front of the degree, grasp the initiative of learning, and deepen learning after learning the knowledge.
Insist on 1: Insist on proper exercises. Mathematics learning is inseparable from practice, which should be targeted and targeted at places that are easy to make mistakes or do not understand. After practice, we should sum up, summarize and reflect, and we should not engage in naval battles.
Persistence 2: Persist in correcting homework. After handing out homework every day, first look at the mistakes in the homework. Before you finish your homework, you must correct the mistakes in the last homework and understand this type of problem, so that you won't make mistakes again. Persistence 3: Persist in consciously cultivating your good thinking habits. Learning mathematics is actually learning thinking, and the learning method of mathematics lies in diligent thinking and hands-on. When encountering problems, we should have the spirit of never giving up, sum up what we have learned in time, and analyze and improve the weak links.
Learning mathematics requires exploring spirit. When I saw Wang Yang, I thought there were no mainlanders, but poor explorers. ※. bacon
Practice is the magic weapon to get good grades. ※.
Make good use of three "books": homework book in class, homework notebook/correction book, use two-color pen well and learn to ask questions.
Dear students, it is difficult to learn math, but it is also very interesting! As long as you build up confidence, be good at thinking, and work hard in your study, I believe that your math learning ability will become stronger and stronger, and you will gain more and more confidence and the joy of success!
Teaching plan two, the first lesson of eighth grade mathematics;
1, to understand the campus security risks.
2. Master safety knowledge and cultivate students' awareness of "cherishing life and putting safety first".
3, disaster prevention and emergency prevention education.
Teaching emphasis: master safety knowledge and cultivate students' consciousness of "cherishing life and putting safety first".
Teaching process:
First, there are security risks on campus. (Ask students to list some phenomena)
1. Safety hazards of student assemblies, group activities and recess activities.
2. The hidden dangers of students eating and dining.
3. Students' traffic safety hazards.
4. Hidden dangers of hidden injuries on campus.
Second, the safety issues that should be paid attention to in student gatherings, group activities and recess activities.
1. What should I pay attention to when going up and down stairs?
Don't run away because you are in a hurry. (2) The railings must be held in crowded places. ③ When the whole team goes downstairs, keep a certain distance from their classmates. (4) Don't put your hands in your pockets when going upstairs and downstairs. ⑤ Don't bend over to pick things up in the corridor, and tie your shoelaces. ⑥ Go upstairs and downstairs and turn right.
2. In collective activities, all actions should be observed, punctuality, discipline, order and civilized language.
3. What should I pay attention to during recess activities?
The outdoor air is fresh, and the activities between classes should be outdoors as far as possible, but don't stay away from the classroom, so as not to delay the later classes.
(2) The intensity of activities should be appropriate. Don't do strenuous activities to ensure that you are not tired, focused and energetic when you continue to attend class.
③ Activities should be simple, such as doing exercises.
(4) Activities should pay attention to safety, avoid fierce chasing, avoid sprains, bumps and other dangers.
Third, the safety precautions for students' eating and drinking.
Don't eat expired and rotten food, and put toxic drugs (such as pesticides and rodenticides) in a safe place.
It is forbidden to buy food made of bamboo sticks: oil is reused, bamboo sticks are easy to hurt people, food hygiene is not guaranteed, and fried food has carcinogens.
Fourth, traffic safety precautions.
1. Pedestrians should walk on the right. When crossing the road, they should take the zebra crossing. Pay attention to traffic, stop at the red light and follow the traffic rules.
2. Precautions for taking the bus:
(1) After the car stops, you can get on and off. Pay attention to order when getting on and off, and don't be crowded.
(2) When riding a bus, stand firm, don't put any part of your body out of the window, there are many people, pay attention to take care of your belongings and beware of pickpockets.
(3) Pay attention to the etiquette in public places, keep quiet, keep the environment clean and tidy, and offer your seat to the old, the weak, the sick and the disabled.
