This is one subject that does not go away once graduation is over. It is a subject that everyone is faced with on a daily basis. One may not realize it, but everyday math is out there, whether it is at the local grocery store or in the classroom. Keep the subject fresh in the mind, and the person will succeed in life.
If you find that your child is still really struggling after a number of efforts at home, there is one final thing you can do. The option of hiring a personal tutor is becoming more popular throughout the States. Personal tutors can help your child get to grips with things they never used to understand and provide a more personal form of education. The personal tutor will become more of a friend to your child, than a teacher, meaning the teaching style will be vastly different to that of their school. It's one of the best ways of helping a struggling child.
