I finally figured out what to do about the fact that Saxon 8/7 lessons took my son far far too long to complete (3 hours???? sometimes) if we did the entire lesson including Facts Drills etc. But by the time I'd figured it out, he was already in Algebra I. So this is for the parent or child still struggling. If I had it to do over again, I would do time4mathfacts style gaming to memorize math facts. I would do any kind of video/fun style memorization tool or card games like in Singapore Math instead of the daily trudge through the wretched math facts. There's already going to be a sufficient trudge through the lesson and the Mixed Practice. It's not like the rest of the lesson isn't hard enough to build his character/ concentration/ focus. Now that we are in A1, I have him do odds or evens each day for the mixed practice (odds for odd numbered lessons, evens for even numbered lessons). For those of you who are already shocked and offended by this idea, just hold your horses a second. If he gets only 1 (or 2)wrong, we move on to the next lesson. If he gets more than a couple wrong, then the following day we do the alternate problems for that same lesson and see if his accuracy improves. If it doesn't improve, we go to the Lesson for the main problems he's missed (he usually only misses one kind of problem) and we rework that lesson and do the alternate problem set from this lesson. I feel like this solution has worked. After all, if he's making 100s, I'm not sure he needs to do all 30 because that does take a long...long...long time to do all 30 problems. Some might even say...two times as long.
