On the way to school this morning, we saw a truck that looks like the one our neighbors have. I mentioned to him that they have two trucks like that – he upped the ante and said they had three: two blue trucks (demonstrated on one hand) and one white truck (on the other hand). Then he looked at his fingers and said “that’s three trucks. One, two, three.”

I thought I’d see if we could move up a number, so I asked him how many they’d have if they got another white truck. I showed him the two blue trucks on one hand and the two white trucks on the other. I asked him “How many is that?”

“5”

“Nope, but close.”

“6” (Giggling, which makes me think he knew the real answer.)

“You’re just being silly now.”

“A triangle!”
