Three teachers answer questions submitted by Slate readers.  Today's big question: "How do teachers respond when they don't know the answer to a student's question?" Hosted by Matt Collette of the Teacher Project at the Columbia University Graduate School of Journalism.

Our teachers: 

- Valerie Lake, an eighth-grade English teacher and literacy coach at Lower Manhattan Community Middle School in New York. 

- Matt Dicks, a fifth-grade teacher at Wolcott School in West Hartford, Conn. He’s also an author, storyteller and a 17-time Moth StorySLAM champion and two-time GrandSLAM champion. You can read his blog at matthewdicks.com

- Erin Huber, a third-grade teacher at Harriet Bishop Elementary School in Savage, Minn., a Twin Cities suburb.
