Answer:
Taken from a mine and then locked up in a wooden case. I am used by students everyday.

What always goes to bed with its shoes on?
Every night I'm told what to do, and each morning I do what I'm told. But I still don't escape your scold. What am I?

Runs over fields and woods all day. Under the bed at night sits not alone, With long tongue hanging out, Resting at your feet until we go for a walk
