Who is the teacher here ?

This morning we were grouping like items. One group was a turtle,a hair brush,a cup, and a comb. I asked Dylan which ones were in the same group. He colored the comb,then he said the brush, he colored the brush. I said good job! I thought he had it,but then he said cup and went to color the cup.I said no don't color that, it doesn't belong. He said yes my mommy puts that and that in my hair (pointing to the comb and brush )Then he put his hand over his head and said Mommy puts water on my hair with a cup. How smart!
One page was drawing lines to match, then we went to the grouping page.The page is divided into 4 sections. One has a big bird, a nest and a spoon. Colton put a X on the spoon.I said you got them all right. I was getting ready to pick it up when he went to draw a line I said don't mess it up. when I looked at his paper he had drawn a line from the spoon to a plate in another group!
They were both right I guess they did understand. Pretty good eh
