Interest is the best teacher. I don't know what grade your child is in. The topic can start from the most basic and simple, let children get used to success, and parents praise and encourage them appropriately. Spend more time to find some interesting math problems to finish with children, and eliminate the fear of math in a subtle way.

Don't blame the child for failing the exam. But to find the reason with him. As a child, parents should teach him patiently, which is much better than those tutors. There is nothing wrong with parents being their children's first teachers. Family atmosphere has a great influence on children's growth.
