It is not enough to cultivate children's interest in mathematics just by attending classes. Or divorced from real life, it is not enough to cultivate children's interest in mathematics only by attending classes. That's just for exams and competitions.

explain
Parents can give money to their children when they go to the supermarket to buy things or go to restaurants to eat, and let them calculate the bills and get change. In this way, arithmetic is no longer a cold and boring number, but the pocket money you may get, which is also your responsibility. In this case, children's enthusiasm for learning mathematics will be aroused unconsciously.
If parents can integrate stories or real family life into mathematics learning, children will feel that mathematics is not just boring numbers, but very important and practical skills, which will stimulate their enthusiasm for learning mathematics.
