Sorry, Neato. Looking back, I think that was the problem with EPGY, too. You have to do all the problems before you can move on. I just saw on homeschool buyers co-op that they have a Destination Math that is tied to the Saxon Math curriculum. Makes me think that they just change the order of what they have and CTY may be a bit different (or more streamlined?). My DS liked it b/c he liked Digit, the colors and the animation. I think we're going to try Singapore so he gets used to writing his answers, and use either HeyMath or Destination Math to supplement/mix it up.
