*I* really like BJU English. It is something that you will have to sit down with him and "teach" the lesson, then they do one worksheet. You do the front side with them to make sure they are understanding the material then they do the back independently. If further review is need there is a CD ROM in the back of the TM for printing more worksheets. I have tried FLL(dd likes it but I wanted a little more application), Rod and Staff(daughter didn't like all the writing, I didn't want to do it orally), and A Beka. I find this is just the right amount of teaching and written work.
**BJU alternates the units between grammer and writing, just to let you know. We use another writing program and don't do those units but they look gentle in 2nd grade(what we are using).
