Selected 6 600 word Elementary School Mathematics Lecture Notes

1. On the basis of understanding, write down the main points and mistakes of the teacher;

2. Write down typical example questions, mainly remember the idea of solving the problem, if you can't write it down, refer to other people's notes in class;

3. You can briefly remember the content of the teacher's lecture in class and organize it after class;

4. Regularly sort out the content learned, classify and summarize; In addition, make a note of your weaknesses and pay attention to them;

5. Error correction notes should also be prepared.

Write down the example questions that the teacher said in class! This is very important! Then with an explanation, with a theorem, the theorem that the teacher said, the derivation process of the theorem are written down, the teacher said that the important mark, or marked with a red pen, pointing out which place is easy to make mistakes, which house uses what theorem.

Lecture records are to write down the syllabus of the lecture or some places that are worthy of scrutiny or classics. There should be your own evaluation next to it. If you just want to cope, just borrow the lecturer's textbook and copy it.

Sort out the example questions, exercises, and knowledge points taught by the teacher.

Today we invited Tang Yuqian's mother to tell us about "mathematical black holes".

She told us: "There are many types of math black holes, let's learn the easiest first!" Do you think it's good?

How many even numbers are there in this column of numbers, and then count out how many odd numbers there are in this column, then write these two numbers on paper, and finally calculate the sum of these two numbers, and then arrange a new number in the order of even, odd, and total, and keep following this order, and finally get the three numbers of 123. She continued: "If you don't believe me, you can try!

So, we tried it with great interest, and we really couldn't escape the three ordinary numbers of 123! Then, Auntie asked us to come up with a question to see if we could escape from the 123 black hole, everyone spoke enthusiastically, and when it was Bao Haoyu's turn, he had a problem, and we didn't calculate it with all our efforts. Later, I went home and used the calculator to get the results, but, to my surprise, it still did not escape from the 123 black hole.

At school, my aunt also told us about 495 black holes and 6174 black holes. After we understood the mathematical black hole, my aunt praised us for being on a par with scientists! Maybe in the future, some of the students in our class will become a world-famous scientist!

We all listened to this math lesson with great relish, and let us understand that there are not only black holes in astronomy, but also in mathematics, and black holes in mathematics are still very interesting!
