"What are these doing here?" a student asks.
"Yeah, they're slates. You've used them, correct?"
"But this is a pencil classroom. We have paper. What are we doing with individual slates?"
I explain to my students that there are times when students will use paper and times for pencils and times for slates.
"But slates are so old school!" the student explains.
"True, but so is the human voice. Don't we still discuss things in class?"
"I thought you believed in the twentieth century classroom?" the student points out.
"I believe in learning. Ultimately, that's what it's all about."
