My son is currently in 4th grade and the problem is that all four years he has hardly studied math, so now he doesn't understand it at all. What should I do in this situation?
Perhaps the only sensible option in your situation would be to hire a math tutor, but the problem is that finding a good tutor is incredibly difficult these days. At least I've had a tremendous amount of trouble finding one. Fortunately, I was lucky enough to come across these online math tutors for 4th grade. These guys turned out to be real professionals. My child was delighted with the lessons with them and very soon his grades in math were much better.
