So I thought DS4 was slowing down in math a little because he's been writing addition sentences and skip counting patterns for quite some time, but he wasn't really moving onto subtraction. He could figure out the answer to a given "subtraction scenario" but he wasn't writing out problems. Not that it matters, but it was just odd to me. It was one of those times where found myself thinking, "Well maybe the gap will close. Maybe it will all even out by third grade."

Then a few days ago we were reading a book about the planets & DS was quite impressed with some of the negative high temperatures listed. The next day he was writing while I was making dinner. When I looked at the paper there were several subtraction problems with negative answers (eg, 20-50=-30). Sooo... Maybe the gap won't close after all.
