Think about examples. Basically, all the exam questions are from examples or similar questions.
If children can understand the normal problem-solving ideas of examples of various knowledge points, it will be much easier to do other problems. Usually, children can look at the stem of the example first, write their own ideas on the draft paper first, and then check the correct method to solve the problem when they are sure that their answers are correct or they can't continue to do it, and see where their ideas are wrong, and then correct them.
Practice properly. Admittedly, it takes practice to master mathematics, but that doesn't mean you have to use the tactics of asking questions. For weak knowledge points, children can do about 5 exercises every day (simple exercises such as basic exercises can be around 10), and the best practice time is within 40 minutes. So as not to affect the active thinking or produce resistance because of brain fatigue. In addition, when the child finishes exercises and homework and understands a wrong question, you need to give her timely affirmation, give her a sense of accomplishment and enhance her self-confidence in learning.
