He made need a bit of assitance to crack the code, although not necessarily with direct instruction that looks traditional.
Does he like to do art at all? Would he think making funny posters is interesting. Wanted signs and such? Would he like to make lables with you for his lego bins (or whatnot). What about a family word wall? A giant white board where you leave notes to each other, plans for the day, and make marketing lists etc? WOuld he like to help you make 'to do' lists or a shopping list...not in a osund it out way, but you just tell him how to spell stuff. "We are need apples..A P P L E S". etc My kids also like making books-- lots of paper staples together, and they would dictate the stories to me. We'd read them often and eventually they started writing short words on pages themselves.
I agree about comic books too, reading Callvin & Hobbes, Garfield, Peanuts etc together (even if you do all the reding right now) can be helpful
I would also point out to him that he can read. Knowing Logos is a type of reading, fi.
Magnetic letters or stickers can be fun for some kids. I dont mean the big colorful ones for littles, but more like those larger sized poetry ones.
