Summary of the seventh grade real number mind map
The application of mind mapping in mathematics 1. What does mind mapping in mathematics learn?
1, what is it? First of all, remember the basic concepts of mathematics, make clear the definition of each concept, then turn the concepts into symbols you understand and make images in the mind map.
2. How to do it: Each problem has its solution method and ideas, which can be written in the mathematical thinking map step by step.
3. What's the use: remember the conditions of knowledge with a mathematical mind map, and then remember when to use it and what's the use.
Have a good memory of mathematics;
Mathematical mind map is the best way to remember mathematics, which is mainly divided into the following three steps:
The first step, after reading the knowledge in the book with your brain, draw a mathematical structure diagram in your mind through memory.
The second step is to draw a mathematical mind map, study some keywords, routes and other attributes, and draw a map in mindmanager.
The third step is to connect the mathematical mind map with the brain, that is, every time I see this knowledge, I will draw a mind map of this knowledge in my brain, which becomes the link between them.
Mathematical mind map learning mode
1, preview: before class, know what the learning content is, what the focus is, and what to distinguish.
2. Listening to the class: In the process of listening to the class, constantly check the mathematical mind map made in the preview, fill in the missing ones, and summarize the knowledge content that the teacher said.
3. Do your homework: Before you do it, look at your mind map after you make it up in class, then solve the problem, and then learn the corresponding mind map when you can't.
4. Review: Reorganize the mind map that has been drawn, and then form a bigger mind map. It is best to put books, reference books, good topics and knowledge on the mind map.
Seventh grade real number knowledge points summary main knowledge points:
1. Related concepts of real numbers (real number, number axis, reciprocal, reciprocal, absolute value, divisor, scientific notation, etc. )
2. The roots of numbers (square root, arithmetic square root, cube root and n root)
3. Real number operation
4. Power of fractional exponent
Senior high school entrance examination results:
Generally choose one question to fill in the blanks (4 points for each question); 19 may be a real number calculation problem (10 points).
In addition, real number calculation is also the basis of all topics related to calculation.
Key points and difficulties:
1. There are many concepts about real numbers, which are difficult to sort out.
2. Accurate understanding and correct expression of square root, arithmetic square root, cubic root and n-th square root.
3. The significance of fractional exponential power and negative integer exponential power
Importance: (The point is not the difficulty, but its importance; It is the cornerstone of the whole mathematics and must be consolidated.
This is the last time to learn numbers, and it is a systematic combing and summary of all previous concepts about numbers; At the same time, it is also a solid concept and calculation basis for learning algebra well.
