Hi, Ive just been thrown into a Montessori class with no materials or training. I guess Im supposed to figure this all out. It is a 1st , 2nd, 3rd grade combo class. Im all alone. My question is, how do i teach 3 rowdy grades successfully at the same time? And how do I grade in a Montessori class? I havent been given any guidelines. Is it just like make assessments and make up some sort of report card for them? Is this all my own design that I just kind of make up as I wish? Is that how it works in Montessori? Help me please. Thanks.
