I've never bothered to break them - why would you want tiny bits of spaghetti? Also wouldn't noodles be something completely different - like when I think "noodles" I think of an Asian dish, not a plate of spaghetti.
I find breaking in two as a bunch convenient since it makes it slightly easier to manage lengths. I do smaller for my daughter (2yo) since she struggles with scooping up the long ones on her own but is fine with smaller bits.
Take the bundle of spaghetti of spaghetti in one hand, place it vertically in the pot with boiling water, push down on the bundle from the top with your other hand. As the bottom part heats up and moistens the spaghetti will become immediately pliable and start going down and spreading out (in an appealingly geometric fashion), within a matter of seconds. You could cook 10" spaghetti, whole, in a 5" diameter pot with no problems.
And the reason I figured this would be weird is that long pasta is easy to eat with a fork. Probably not worth dwelling on this though as it's offtopic so people are downvoting :D
