The grade of grade three is really not optimistic. What you need to do is to find out the cause of the problem. Find a math researcher or a primary school psychology teacher. Find the crux of the problem and you can prescribe the right medicine. The US Department of Labor has determined that people have eight skills, and there are eight ways to learn these eight skills. Everyone has the best one, so it will be easy to find the crux.

There are 64 questions to be tested in those eight skills. You will know what kind of child you have after you answer the question.

I suggest you watch an Indian movie: Children from the Stars. It is good for both parents and teachers.
