We initially were attracted to RightStart’s approach, but chose another option because of cost. However, after 2-1/2 years in 2 different programs, we switched our son to RightStart level D and started our daughter in level A. I can say that the upfront cost of the manipulative set is worth it. My kids are developing a conceptual understanding of math, learning math facts, seeing visually how concepts work, discovering patterns in math for themselves, and having fun playing games. It is very teacher involved until mid-late elementary, but worth the effort. My son’s attitude toward math has improved greatly since starting RightStart, and my daughter is starting out enjoying math. We plan to continue using RightStart through all levels.
