First of all, follow the law of students learning mathematics. The most important thing in primary school is the ability to calculate. Calculation is a technical activity. If you want to reach a high level, you must do quantitative exercises every day. At the same time, students' personal knowledge, direct experience and the real world should be regarded as important resources in mathematics teaching, and the combination of mathematics and problems that students are interested in in in real life should be strengthened; As for the amount of practice, this actually varies from person to person, depending on your definition of "learning math well". As far as regular in-class learning is concerned, it is generally recommended that children make two synchronized workbooks when learning new lessons, with the best moderate and slightly higher difficulty.

Finally, it is emphasized that home-school education should form a joint force and attach importance to the cultivation of students' study habits. Generally speaking, it takes 2-4 years to form a study habit. Once it is formed, it is difficult to make a big change. If you grasp the key of 2-4 years first, then you don't need to worry a lot about your child's future study; On the contrary, I have nothing to worry about if I miss this time.
