Sorry I didn’t see this sooner. We are no longer using Right Start. It did serve its purpose well for us for a season though. We used 1st edition levels B and half of C. I probably should have kept using it through E, but at a slower pace. Since my oldest struggled with math, I always felt pressured to do more instead of going at his pace. I should have used a timer because too often the lessons got too long. When they go too long, it was no longer enjoyable and became less productive. But I thought I had to keep up the pace so we wouldn’t fall further behind. I ended up switching to a more independent math.
Since January 2017, I learned more about CM math lessons from the book and DVD set sold here, by Richele. I highly recommend this set. By adding oral stories with the number problems, math is more enjoyable and my children see the use of it better. I won’t switch curriculum until Algebra I. But, adding the stories to our current math curriculum and adding oral mental story problems from older texts like Strayer Upton has helped. We also learned how to use a timer for our lessons and be satisfied with what progress we made. 🙂

One benefit of the CM method is when I ask “why?” (narration). Then I know their math strategy. This is where I think Right Start helped. They taught mental math strategies well, like adding the tens and then the ones. Or rounding 58 up to 60 and then subtract 2.
However, I am not at all familiar with Abeka math. I don’t like switching between math curriculum though. Please let me know if I can be of any further help.
