We currently use Math U See for our older children and The Good & The Beautiful for our younger children. In the past we have used many other curriculums, like Saxon, Alpha Omega Lifepacs, Abeka, and a few online curriculums, some of which our children did very well with some not so much. It really depends on how your child learns. We are really enjoying the videos that accompany the Math U See textbooks. The teacher does an amazing job explaining each lesson. The math curriculum from The Good & The Beautiful is a thorough and complete curriculum.
