Whether it is necessary for children to study and sign up for tutoring depends on their mastery of first-grade mathematics and whether their parents have the ability to tutor independently. If the children's math scores are already excellent, or parents have enough time to educate and coach their children, there is no need to spend extra money on extra tutoring. On the other hand, if children's autonomous learning ability is poor and their foundation is weak, parents don't have much time for counseling, so taking part in counseling is also an option.
