This is the first time she's ever taught elementary kids. That is one thing I should say!
What?!?! Is that the norm? That seems insane, how can you be the principal of an elementary school without ever teaching elementary students?
My SIL was aMS teacher and then an elementary school principal. You have to have your MS in administration...
Now, maybe she'll let you do your job...the right way. I can understand giving your emplyees the tools and opportunities to do their job better, but trying to show them up is rude, and apparently backfired. Hope she realizes how ridiculous she made herself look.
