Last week I read to my class a book about dinosaurs. At the end of the book, it talks about how the dinosaurs don't exist anymore. The following conversation occurred:
Me: "So, can anyone tell me what the word 'extinct' means?"
Kid #1: "It means you don't live anymore."
Me: "That's right, good job! Can anyone think of other animals that are extinct."
Kid #2: (raises hand) "Um yes, unicorns."
Funny, I thought I saw one on the highway just yesterday. :)
