Those reading worksheets look perfect! Thank you.

He seems to have skip counting down already and can do a lot of simple-ish math in his head (things like 26 + 7 are no problem). I didn't teach it to him. I'm not sure how unusual this is. DD has taught him the concept of multiplication, and he seems to get it, but is only able to calculate so far. I just asked him some double-digit addition and he wasn't able to do that in his head. I don't know if he can really do it without a scribe, since his writing is iffy.
