So I obviously have those 2 or 3 kids in my classroom that if they were gone, things would run a lot more swimingly.  So I have devised a master plan.  I sit those kids with the students who are sick on a regular basis in hopes they would spread the wealth...Its a shame they dont teach you this in college, because it actually works!  Things will get better, im not sure what life is like in 4th grade but i can definately relate to what your saying, ive thought about switching to almost every profession available, and ive only been in school a month!!!  Your problem is universal, im sure every first year teacher feels the same...and so many teachers stick around for so many years so it obviously will get more rewarding as you go.
