I don't dread school. My high school experience was actually fun. I think it shows. If teachers create a "learning is never over" environment rather than "stress the test" environment then they can pull knowledge (and great lessons) out of kids.
I have fun teaching. Work shouldn't be a place you have to go, you should choose to go. I live by that code. Math ( and all subjects) shouldn't be something you have to do but you should want to tackle. If you get the fun (or Positive energy) you get the want. If you get the want, you don't have to worry if the students will ask you a pivotal question taht will make the lesson so much better than if you just give away the knowledge. They just will.
They will want to.
