Find it with the help of a line graph. For some application problems, it is easy to find quantitative relations by using line segment diagram. Especially for the application of fractions, the key to using this method is to find the unit "1".
I have been in contact with many children. Some primary schools seem to have done well in the exam, but the main reason is that the backrest has come out. A child who has tasted the sweetness through his back is afraid to give up this method. The result is the misfortune of senior students, because you can't recite it anymore, and you need to explore, summarize, analyze and judge it yourself, but sadly, many children have not developed this ability.
So, again, parents and friends must not blindly believe in the Olympic math training class. No more than 5% are really suitable for participating in the Olympic Mathematical Competition. Some Olympic math problems can open children's thinking, classic Olympic math problems, improve children's interest and give them a sense of challenge.
However, don't go too far, it's too late! Remember what our ancestors said, throwing our children into the Olympics class too early may destroy their confidence!
Many children are sloppy, but some sloppy are actually caused by students' unclear understanding of knowledge points. Such a topic must be recorded. There are also traps deliberately designed by questioners, which can also be recorded and reviewed regularly. After a long time, many carelessness will naturally be avoided.
Like the wrong question book, it records the questions that children have done. Classification refers to the classification of the questions you have done. One kind is extremely simple and can be seen at a glance. One kind is difficult, which requires thinking to find a breakthrough, and the other kind is difficult, which requires comprehensive application of a lot of knowledge and truth to solve. The latter two should be the focus of the record. In the process of classifying test questions, children.
Almost every training institution is emphasizing the importance of junior high school. Take the fifth grade, where parents shop the most intensely, for example. official website, who is learning to think, said, "As a fifth grade student, there is only one thing to do: become an excellent student faster before the opportunity comes!" Giant Education emphasizes that the 20 18 "Mathematics Garden Exploration" Cup is coming soon, so we should actively prepare for it, because its "difficulty setting" has a relatively high level. It can objectively examine students' knowledge of Olympic mathematics and the flexibility of mathematical thinking to a great extent. This is also one of the reasons why many key middle schools attach great importance to it. "Gaosi Education listed" 2065438+2008 Xiaoshengchu Preparation Raiders ",in which a parent who went ashore posted his own experience, saying that" this is a battle ".
