Since writing my original post, I've done a lot of praying and thinking. I've also talked with my 10 yo. He expressed that even though Preparing was hard for him when we tried it last year, that he really did like it. I took out my manual, and realized that we had only completed 3 units. I was surprised at how much he remembers from that short amount of time.
Here's what I'm considering. Let me know what you think

ds10 Preparing Half Speed and DITHOR with 2/3 workbook. We may pick up to full speed as he progresses. If he is struggling after a few weeks, I will probably order Bigger.
dd7 Beyond Half speed until we get a routine down, then we'll move to full speed. Also scheduled Emerging Readers
ds4 LHTH...will add this after we get a routine going with the other two.
I know that this puts me doing three programs, but I feel that easing into it at half speed will ease that adjustment.
If by any means you think that this is a stretch...please let me know. In the end, if you think that this will not work, I'll probably just put them both in Bigger . After reading your last post, I realize that I would have to do way too much tweaking for ds10 with Beyond.
Thanks so much for helping me to work this all out. I wish that there was a HUG smilie because I'd give one to you, Julie, and ALL of the ladies on this board


Blessings,
