Yesterday when I picked up my 4-year-old from daycare, he looked toward the street.
"Eight sides," he said.
"What has eight sides?" I asked.
"The stop sign," he replied in a tone that suggested I wasn't keeping up with the conversation.
"That's right. Do you remember what shape has eight sides?"
He was quiet for a moment as he tried to remember. Then his eyes brightened as he finally remembered.
