Apart from mathematics, we should not underestimate reading. Cultivating children's strong interest in reading can not only effectively solve the problem of children's lack of learning ability, but also help children effectively avoid indulging in video games. Children who really love reading scoff at playing video games.

In addition, for some training courses attended by most children, the qualifications of teachers are mixed, and some even have a poor grasp of primary school knowledge, which is naturally unprofessional. Then it leads to children's preconceptions after the first grade, which is difficult to correct after school, affecting the learning progress.
