Thanks for all of your input ladies! It seems like he probably will be ready for it, I'll just have to take the $7 jump to get the 1st workbook and see if he likes it. He really enjoys all the X-ing out, and drawing lines to matching letters, etc, hopefully they'll be enough of that element in the regular series as well.
B&W's no problem for him, I've been letting him to the primers in colored marker but I think I make make him switch to pencil after the primers, if we do end up buying all EIGHT of the regular books I'd like to be able to erase and re-use the series instead of re buying. And if It doesn't work out then we'll look into something else.
Thanks again, you're all awesome :laugh:
