We all like our teachers - even if they do sometimes give us really boring homework!
But have you ever had a terrible teacher? Like we're talking totally terrible - the kind of teacher who doesn't understand maths and decides what to teach by throwing darts at a dart board?
Well, if that kind of teacher sounds unusual to you, then you haven't met Miss Cooper.
Primary school teacher Miss Cooper was recently named 'Most Unbelievable Teacher of the Year'.
She lets the kids do whatever they want, she can't control them...
But she thinks the award means she's a really good teacher!
