unschooling reading

Jack, age 5, is chugging along.  He's up to lesson #20 out of 100.  He has a bit of trouble with reading comprehension but he's doing well with the mechanics.  Remember that I have not taught Elazar, age 7.5, any reading at all.  He only knows what he learned from minecraft and google searches.

Yesterday, he was looking over Jack's shoulder at what Jack was reading and he said, "How come all these words are so easy?"

Jack and I spend about 10 or 20 minutes most days, at his request, doing the reader.  Elazar has never sat down for formal lessons.  Yet Elazar can read all those words.
