I first wrote about the importance of mathematics, and then gave many examples, such as "often asking children to help calculate the price when buying vegetables" and "teaching him to count early", saying that children can find mathematical phenomena that parents can prompt and inspire in their lives. In view of this, I explain that mathematics is everywhere, and then talk about some effective methods to improve children's mathematics level. In short, the theme is that there is mathematics in life, and children have many opportunities to improve their mathematics ability under the guidance of their parents in life.
