Hi Lori,

It�s interesting that you attribute skip counting and time telling to understanding coins. I don�t remember when my son understood money or analog time, but it was certainly before 1st grade (he never attended K). I do know he could skip count by 5s or 10s into the thousands right after he turned four. Those skills probably do compliment the development of the other. I think they are all 1st-2nd grade skills around here.
