We have completed level B and are part way through level C. This is an excellent curriculum. Although it is somewhat teacher intensive the lessons are well laid out and build well upon each other. This is a spiral method in that different concepts and introduced and then may be set aside to come back to later. The bset part of this program is the games. There are hundreds of games each of which pertain to a concept taught in the various levels. We did have to slow down on level B, but my dd is getting the ideas and understanding math which is my goal.

I Love it too. It is simply excellent. I just started with it (don't you love people like me - who review something they've just started!)....but I'm really pleased. I had been using Math U See, which is very good, but I really needed more daily direction as a teacher. I'm sure I was much of the problem. But we were not making strong and lasting progress with it. My child is very bright, but she was not retaining the learning. And I felt like I needed more ways to tackle a lessons - different tricks in the bag. Right Start really provides this. Working with the abacus is more straightforward and is clearer to my daughter than anything else I've seen. And it's just fun to use. I've watched my children (4 & 6) have several lightbulb moments where they've said, "OH, I see!" They are understanding this. I do the lessons primarily with her, but I require my son to sit at the table with us and draw so he can learn with "one ear open!" Take a look at it for sure, if you are looking into math programs.
