Just sent u a link. Seems like Super Why was a huge hit at that age. They take sentences & change them to change their meaning. For example The Big Bad Wolf they change the words big and bad to make him a small nice wolf. Turns out he's mean because he's never had anybody to play with. He likes being nice, but he'd prefer to be big. So they change the right word in the sentence- now he's the big nice wolf.
My boy was apparently just picking up sight words (like his dad's name) at that age and not sounding anything out, although I was teaching him letter sounds and sounding out to get him ready for phonics. We were using hooked on phonics word families where you use a deck of alphabet cards and write cat, say "now give me the c and put this r there and and sound out r-at". Teaching gifted kids schooly-style doesn't seem to be the recommended best practice, but I wanted him to learn how to learn the style that most people are likely to teach more than I wanted to let him learn how to read. I thought by teaching him how to follow lessons he can learn whatever he wants in a minute. I might have over thought it somewhat.
Ps, that pic on that page was my boy content and exhausted. We bought that shirt at Six Flags and that was at the end of a long day at the amusement park.
