Senior one mathematics knowledge points
Front-back (front-back positional relationship)
1, pay attention to the difference between describing the order of objects and describing the exact position of objects with words like before and after.
2. The deer is in front, who is behind? The answer is no, not only a squirrel, but also rabbits, turtles and snails are behind the deer.
3. Pay attention to let students describe the relative position of objects with words like before and after.
Up and down (positional relationship between up and down)
1. Understand the relativity of "up and down" in specific situations.
2, can use language to express the "up and down" position relationship of objects in actual situations.
Left and right (positional relationship between left and right)
1, you can describe the left-right position relationship of an object in language.
2. Can experience the relativity of left and right positions in the situation. Further understanding: if two people face the same direction, they see the left and right positions in the same order; If they face each other, they see the left and right positions in the opposite order.
Classroom (front and back, up and down, left and right comprehensive application)
Describe the position and order of objects by using the knowledge learned in the first three lessons.
Knowledge points of mathematics in the first grade of primary school
1.
Understand the meaning of up and down: from the position of two objects: up refers to the high object and down refers to the low object.
2. Knowing the past and knowing the future
Understand the meaning of "before and after": Generally speaking, the facing direction is front, and the facing direction is back.
The same object will also change its positional relationship relative to different reference objects.
From this, it is concluded that when determining the front-back position relationship of more than two objects, it is necessary to find the correct reference object, and the relative front-back position relationship will also change with different reference objects.
3. Know the left and right.
Determine the left and right sides according to the positions of your left and right hands. The side where the right hand is located is the right, and the side where the left hand is located is the left.
Math learning methods in the first grade of primary school
First of all, listen to the teacher carefully. This is the main reason why I got good grades. Listen attentively, follow the teacher's thinking, don't be distracted, and don't listen at the same time. Secondly, we should pay attention to every word the teacher says, because mathematics is famous for its rigor, and there are serious differences between words, and there are infinite mysteries hidden between words. Pay attention to taking notes when listening to the lecture. Once the teacher talked about a difficult geometry problem, which I didn't understand at the moment. Fortunately, I wrote down the problem and the solution, thought it over carefully when I got home, and finally understood it thoroughly, so that I easily solved a similar problem in a competition and got a valuable score of 10. Raise your hand to speak actively in class. The benefits of raising your hand are really many! (1) can consolidate the knowledge learned in class. (2) Exercise your eloquence. Those vague ideas and mistakes can be taught by teachers. It's killing three birds with one stone. In short, listening should be done with hands, mouth, eyes, ears and heart.
Second, extracurricular exercises. Confucius said, "Learn from time to time". Homework after class is also an important part of learning and consolidating mathematics. I pay great attention to the accuracy and speed of solving problems. Accuracy means accuracy, concentrate on completing your homework independently, strive to be accurate once, and correct any mistakes in time. And speed is to exercise your concentration and sense of urgency. I often do this. I set the alarm clock at the beginning of my homework and put it out of sight, which helps to improve the speed of my homework. I won't be nervous during the exam, and I won't lose sight of one thing.
Third, review and preview. I plan to review math every night. After finishing my homework that day, I will briefly look at the new knowledge I will learn the next day, and then recall what the teacher said. When I sleep in bed, I will "watch" the teacher's class in my mind like watching a movie. If there is any problem, I will get up and look at it immediately until I understand it. Every Sunday, I will also summarize, review and preview the week's homework. This is good for learning mathematics, and you won't forget it if you master it firmly.
Fourth, improve. After finishing my homework, previewing and reviewing, I will do some rock climbing problems. Doing this kind of problem, thinking independently as much as possible and trying to find out the hidden conditions are the key to solving the problem. If you really can't think of it, you need to look at the reference books and consult your teachers and classmates. In short, seeing more, doing more, asking more questions, being open-minded, diligent and keeping a positive spirit are the key.
