When our grandson was here a couple weeks ago, he was exhibiting some facility at identifying circles, rectangles, squares and such. So I showed him this clock one morning at breakfast. I didn't think it made much of an impression. Yesterday, my daughter told me that they had been driving through town, and he kept screaming "ock-a-gon" from his perch in the carseat. She finally figured out he was talking about the stop-signs (which she was probably running, but that's a different story....)
Anyway, I hope all of your clocks are set this morning!
