Please Help!! What is the translation for "Debemus in ludo sedeo et magistrum audio

It makes no sense at all.

debemus = we ought

in ludo = in play (or in game)

sedeo = I sit

et = and

magistrum = ? (magister = teacher)

audio = I hear (or I listen to)

The phrase "Debemus in ludo sedeo et magistrum audio" is in Latin. It roughly translates to "We should sit in the classroom and listen to the teacher."
