Hi SFB - After we had DS4 tested, he of course wanted to know what the dr said. We told DS that he thinks differently than some people, and that some people will need to hear/see something several times before they learn/remember it, whereas he might only need to hear/see something once to learn it. We compared this to his agemates who could do physical things at a higher level than he could.
Your school sounds lovely! I think flexibility is the key for these kids, but it is hard to find.
Finally, i would love to see your grade 3-4 reading list with books appropriate for younger kids.
