That's my plan too...and I have a 4th grade AS son as well. We started FLL3 last year, but took it slow. DS doesn't love it, but tolerates it. I have ordered the WWE level 2 workbook...definately taking the easy-laid-out-ready-to-go plan here. He likes a workbook so he can see what's going to be happening as opposed to winging it by the whims of teacher-mom.
