The process of learning must be gradual, from shallow to deep. Need to follow the learning rules. In view of this situation of children, since parents are not stupid and can give counseling, they need patient counseling. First, we need to find the reason. For example, children's foundation is poor, not to mention elementary arithmetic, even simple addition and subtraction may be difficult to calculate. Secondly, teach children the right way. In fact, mathematics is relatively rigid, and coming over is the definition of problem-solving laws and theorems. For example, what is the operation order of elementary arithmetic! Teach children the ability to solve problems by analogy. Finally, be patient. In the process of learning, you can't always show impatience in front of children, but always complain, which makes children lose interest and confidence in learning.

I hope the above answers can help you and your children. If you agree, please adopt them.
