This math curriculum makes math concepts much easier to learn and it doesn't require much time to teach it. Just be sure your child has plenty of chances to review .

I used singapore math for all of my children. The oldest does not enjoy math but still he is doing exceptionally well in it. The younger ones are always looking forward to it.
