cathmom Posted November 22, 2011 Share Posted November 22, 2011 For anyone who's done all of them, would you advise this or not? My son turned 8 a couple months ago. He's almost 2/3 through B. Math is effortless for him - I don't think he's had to struggle to understand anything so far. I already have D, but don't have C. I was planning just to buy C, but then I started thinking maybe he could just go right to D. I have the transition lessons, we could do any of them he doesn't know yet. What do you think?
