smarter than a fifth grader?

this job is complete karma. i am pretty sure i used to be a total pain in the ass know-it-all with add in 5th grade. being a competitive person who was somehow blessed with an extreme patience with children, the students challenge me each day. they will ask me a question or show me an answer. if it's wrong, i will tell them so, sometimes rather mundanely, other times i am pretty animated about it. my favorite is when the kids will say "it's right, it's right" as though i don't know the answer. not only do i have the teacher's edition, but i have also done the problem or read the story and i am aware of the answer.

generally, this first part of the discussion is ok. but then they continue to insist. this is where i start to get a little worked up. i want to just tell them that i can assure them i am smarter than they are and the answer they have is wrong. not really a good strategy. the ones that persist will generally get ignored, but that's not really fun because then they just become obnoxious and stop doing work.

in terms of the new seating arrangement, i have no idea why they hate each other so much. it seems to be a very forced animosity that is also fueled by the desire for attention not only from me, but also from classmates.
