We have both EFTTC and EG. They are completely different. EFTTC has some picture study, writing assignments, etc., EG is just grammar. I have EG for my oldest who also uses JAG (just wanted something a bit different) but my 9yo can definitely use some of it now, but he’s still finishing up EFTTC. He (9yo) has played Bingo and unscrambled the words on the “unscramble the words” worksheet (not all, but some) and has enjoyed it. My 9yo is not quite ready to only do EG, so we’ll probably use EFTTC Vol. 2, then use EG later. Don’t know if he can handle JAG, EG may be a better fit for him. Okay, nevermind, he looked at EG and said,”No.” He is more into stories and fairy tales, maybe Grammarland would be something he would like.
Hope this made sense.
