Robin was so excited today that his math sheet (I've been giving him the beginning of Wolfy's 1st grade math book that Wolfy didn't use) had "real" addition problems on it, like "2 + 2 = ?" etc. He was able to do them, by putting up the right number of fingers on each hand and then counting them. He was also able to fill in missing numbers on a grid from 1 - 20.
However, it is clear to me that he isn't fundamentally understanding at least some of this. I think we will go ahead and go through Saxon K math next year, at least to start with, so he can really grasp how to write all the numbers, etc.
I think my other favorite thing Robin's been doing is giving and getting lots of hugs and kisses from his little sister!
