I've seen so many music teachers just give theory lessons and then have the student practice the ideas on their instrument. I think – with a lot of people want to study music like guitars, pianos these days – seems too... boring.

For example: A classical guitarist student (which age is 10) is getting bored because the teacher is always giving the student theory lessons and practicing a new song every meeting.

So, how can a teacher make them not bored and teach them the theory and technique for their instrument and how would a teacher help their student enjoy what they're learning?
