One of the first thing you can do with a young child is to try and incorporate basic math into day_to_day life. Children might find that studying math at school is not the most exciting thing, so it's your job to try and make it more exciting at home. There's a few simple ways you can do this that perhaps you'd never thought of before. One great way of getting your child involved with math at home is to let them help you with the cooking or baking. This is a perfect way to teach them about proportions, as they can help you decide how much of one ingredient needs to be used in comparison to another. Cooking can also help reinforce fraction skills as well a measurement when adding specific amounts of ingredients.
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.
