I hadn't thought about his vision. Yes on the denser books. His father read everything I could find published by Louis Sachar last year. He read Wayside school stories by himself and part of Someday Angeline. Then he stopped trying to read the larger books. I thought that maybe he had hit his limit.
I hadn't thought but all the books he likes have almost annotated formatting and his favorites (that he reads for fun) have larger print.
I hadn't made the connection about distraction and underplacement until after the conference. He had talked (actually drawn a cartoon) about being distracted. I was thinking that maybe it was a noise overexcitability.
His cousin who is 2 months older and home schooled is doing 3rd grade math and 4th grade language arts. DS started EPGY at the 3rd grade level 3 weeks ago (he had been working 3a Singapore math workbook, but he had never done drills).
